EMF is an acronym for electromagnetic field, which refers to an invisible field that’s created when the combination of electricity and magnetism radiates outward. This occurs in nature in a variety of ways, as a natural byproduct of charged particles interacting with the magnetic field of the Earth. A couple centuries ago, humans figured out how to produce electromagnetic fields and use them for a variety of practical purposes. If you want to find out more about EMFs and learn about the electromagnetic spectrum, check out our article that explains the subject in depth.

The electromagnetic fields that humans produce and utilize are very different in structure than EMFs that nature produces. Manmade EMFs are usually pulsed, repetitive, oscillating frequencies, which can have a totally different effect on biology than nature’s infinitely varied frequency patterns.

As humanity’s use of electronic and wireless devices has increased exponentially over the past few decades, many have wondered if the invisible emissions from these manmade devices are safe for our health. The result of this widespread concern has been a plethora of scientific studies. The majority of the independently-funded studies, and even a surprising percentage of cell phone industry and government funded studies, have shown that manmade electromagnetic fields from a variety of sources can indeed harm human bodies, as well as other living organisms. While the vastly wealthy telecommunications industries (and the government organizations who supposedly regulate them) try to ignore or downplay these studies, they do in fact exist and carry considerable weight.

How Do We Protect Ourselves?

Now that we’ve established that manmade EMFs do harm living biology, what do we do now? How do we protect ourselves from an invisible element that seems to permeate every facet of our modern lives?

As awareness of this issue increases, and more people than ever before are taking responsibility for informing themselves of the potentially harmful side effects of this fairly new element of the human experience, potential EMF protection solutions are popping up right and left. It is wonderful that individuals and companies are creating and offering innovative solutions, so that hopefully we don’t have to sacrifice our health and well-being for this enticing modern opportunity of greatly increased digital connectivity.

We get many questions from people who are confused about all the options out there, wondering which ones are effective and which aren’t worth the hype, and how to get the biggest return on their investment in EMF protection.

We will break down the different types of EMF protection strategies and devices that are out there, so that you can more clearly understand which ones will be right for you, with your unique lifestyle and needs.


The Best Protection Is Minimizing Exposure

Before we even start discussing ways to mitigate the bodily damage caused by the EMFs you’re exposed to, it’s important to understand that the number one way to reduce harm from EMFs is to minimize your exposure to them. In our modern world, this is nearly impossible to do completely, and undesirable to do past a certain point. Almost none of us, even if you’re a huge lover of the wilderness, are going to go live there full time. Even if you somehow manage to do so, the new 5G satellites being launched into space at the current rate of hundreds per month are especially designed to provide service to rural and uninhabited areas.

Most of us need, and want, to live our lives and do our work in moderately to highly population dense areas, around other humans and human activity. We may choose this lifestyle because we enjoy it, or feel that we need to live this way due to our individual life circumstances. It may be a nice thought to live somewhere where there are zero cell towers within several miles of your home, but for most people this is unrealistic. It’s also unrealistic, and undesirable to most people, to never use a cell phone, computer, or drive a car. We shouldn’t have to give those things up to feel good and maintain our health.

That said, there are ways that you can moderately and sensibly reduce your exposure, even without compromising essential or enjoyable aspects of your lifestyle. Here are a few easy and smart ways to reduce exposure that will go a long way in decreasing the stress of EMFs, when cultivated as habits:


  • Never talk with your phone held against your head, especially during long conversations. Instead, use the speakerphone setting, or an AirTube headset when you need to talk on your phone. If you’re making a quick call, even just holding your phone a couple inches further away from your head (so you can still hear the caller and talk into the microphone) will make a big difference in how much radiation is reaching your head.
  • Never carry your phone against your body, unless it’s on airplane mode or turned off. This means keep it out of your pocket or bra when it’s turned on and the signal is active. Airplane mode is your friend! If you’ve never used airplane mode, it’s worth learning how, and it’s an easily accessible setting on all modern phones. If you need to keep your phone on because you’re waiting for a call or text, at least make sure it’s further away from your body, such as on a table next to you, or kept at a safer distance from your body in your purse or bag.
  • Keep your phone out of your bedroom at night, and keep electronics away from your sleeping area. If your phone needs to be in your bedroom at night, keep it on airplane mode (you can still use the alarm) or at a safer distance from your sleeping area. You could even turn off or unplug electrical appliances in your bedroom before you go to sleep, or turn off the breaker that powers your bedroom outlets. Many people have found that these few changes improve their quality of sleep at night!
  • Turn off your Wifi at night or when you aren’t using it. Wifi is usually the closest range and most intense EMF exposure that many people have. If you can eliminate this one electromagnetic stressor more often, you may find that you feel much better.
  • Don’t use “Smart” devices in your home (within reason). This includes wireless doorbells, baby monitors, and “smart” appliances like Wifi enabled ovens, washers/dryers and beds. You may need to use these devices for certain reasons, but we recommend at least thoroughly assessing the use of each device and deciding if it’s worth the extra EMF exposure. If you have a “smart” meter as your electricity meter, contact your electric company and ask if they can replace it with an older digital or analog meter.


Those are just a few suggestions that can immediately improve your quality of life, without compromising connectivity and only slightly decreasing convenience. With this approach, there will be trade-offs, and you will have to decide for yourself which exposures are worth tolerating, and which ones you truly don’t need.


EMF Shielding & Blocking

One popular approach to EMF protection is using shielding materials to block electromagnetic radiation. These items contain certain metals, often in a grid-like pattern, that absorb the measurable EMFs and don’t allow their passage beyond the material. They are commonly referred to as Faraday shields (or Faraday cages), named after Michael Faraday, who invented them in the 1800’s. Often, they will be simply called EMF shielding or blocking materials. They can be made of cloth (with metal strands weaved into the cloth), solid sheets of metal, or grid-like or cage-like structures.

Often people will put these around their bed when they sleep, or wear clothing made of Faraday shielding cloth, hoping to block the EMFs from reaching their body.

This approach can be marginally effective, with certain key limitations. Shielding will attenuate or fully block the conventionally measurable transverse component of the electromagnetic wave, which you can see if you use an EMF measuring device like a Trifield meter. Your cell phones and Wifi won’t work behind a Faraday cage, because the information they transmit is on a transverse carrier signal.

The problem is that shielding will not block the longitudinal (scalar) component of the electromagnetic wave, which is estimated to be 5 times stronger in its biological effects than the transverse component! The EMF measuring devices available today are only designed to measure the transverse component of the EMF. Many people believe that if these devices can’t measure it, then it doesn’t exist.

Every electromagnetic field contains both a transverse and longitudinal component, as theorized by James Clerk Maxwell and proven by Nikola Tesla, and many others since Tesla’s time. A transverse wave cannot exist without an accompanying longitudinal/scalar field, but the opposite is not true: a scalar field can exist without a transverse component, because the scalar field doesn’t depend on the transverse wave. This is what we call “pure scalar”, and is how Blushield devices work. This begins to get somewhat complicated, but to learn more about scalar energy, and longitudinal vs. transverse waves, read these two article we have written to explain the subject in depth:

Scalar Energy, Biology, and Consciousness

Back to shielding, because of the above drawback it’s important to understand that relying too much on shielding as a primary EMF protection strategy can give a false sense of security. You may think you’re more protected than you are, because you are relying more on the numbers displayed on a meter than feedback from your body. This is understandable, since many people are not very sensitive to subtle energies, so may not trust their body’s signals.

Another big downside to shielding is that in this world, you can’t live in a bubble. You can’t just block out harmful frequencies and exist in a vacuum. You still need to participate in life, and along with living comes exposure to many frequencies, including a variety of beneficial and harmful ones. Even if you have a fiber optic or copper internet connection, making it possible to use your computer internet inside your Faraday cage, most people can’t completely cut themselves off from the outside world, nor would they want to.

If you currently use shielding products and have experienced benefits from them, we encourage you to continue using them in the limited way you can, but not to overly rely on them as a primary form of EMF protection. Here’s a more thorough explanation of the scalar component of the EMF, and why you can’t truly block EMFs:

Can You Actually Block EMF?


Passive EMF Protection

The majority of EMF protection devices on the market could be considered “passive” devices. This means they don’t use electricity to amplify a signal, so are more subtle and inert aspects of your environment. These include various stickers, necklaces, pyramids and stones, as well as some larger devices.

Some of these can have neat properties and do seem to exude some kind of beneficial energy. An example are certain types of rocks, like lodestones and shungite. We think these are interesting and worth having around if you like them, and they probably have some minor protective properties. However, there is no way that the energy these stones exude is enough to combat the extremely high levels of pervasive EMF we are exposed to in modern times. They cannot be considered a primary EMF protection strategy.

The same goes for the many stickers and pendants on the market. Some are meant to stick on your phone and supposedly block the radiation from them, or “harmonize” the EMFs so they aren’t damaging your health. Once again, there is no way that a tiny sticker or inert necklace is going to be remotely strong enough to block or render harmless even a tiny bit of the currently obscene levels of EMFs around us. For the ones that claim to block EMFs, if they actually blocked the signal from your phone, you couldn’t make calls from your phone. Our personal experience with these, and those of everyone we know, is that these don’t work at all and are a waste of money.

Pyramids are similar to the above mentioned rocks, in most cases. The pyramid shape naturally has properties that concentrate energy, and the materials the pyramids are made from often have some kind of subtle energetic properties. Many of them are made of a resinous combination of substances that is known as orgonite, and others are simple pyramids made from shungite or other stones. These can be pretty decorative pieces, and often exude some subtly beneficial energy, but most likely do very little to reduce the harm of EMF exposure.

If you start looking into the higher price ranges, you will find some larger devices that are specifically designed for EMF protection, but could also be considered passive devices. They are all designed differently, some using copper coils, mineral solutions, and gemstones or precious metals. Some contain a liquid that releases free electrons, which are supposed to depolarize the EMFs and render them harmless to the body. They may have some positive effect, depending on the person, but once again, a device or contraption that’s passive (not powered) is going to be more subtle and less powerful, and is unlikely to be able to mostly or completely remove the bodily stress caused by EMFs.


Active, Powered EMF Protection

There are only a few devices on the market currently that utilize mains power or a battery to amplify a signal, to become a strong enough positive influence to match or exceed the negative influence of the manmade EMFs. From our research and experience, only powered devices are strong enough to truly negate the overwhelming levels of EMFs we are dealing with in modern times.

Active devices either plug into a wall socket with a power cord, or run from a battery. Comparing the active EMF protection devices that are on the market, that’s about where the similarities end. The actual content of the broadcasted signal is vitally important. Active devices amplify a signal, but what type of information and frequencies are carried by this strong signal, and how does it work to protect your body from the EMFs in the environment? None of these devices remove the harmful EMFs from the environment, because if they did, your communications devices would no longer work. If they don’t remove or modify the EMFs, how do they help?

Active devices can operate through various means. Some use copper coils (aka Tesla coils) to generate a scalar field. These can have some positive effects, but there are downsides to using copper coils. Read more about that in our article on the subject:

Tesla Coils, Copper Toxicity, and Blushield’s Revolutionary Scalar Microprocessors

Some other active devices use precious metals and gemstones along with lights that slowly release the gemstone particles into the surrounding environment. Other active devices generate what’s called a “noise field”, which is random inaudible noise that is meant to combine with the harmful EMFs to deactivate the part of their structure that causes harm, so hopefully they will impact your body in a less harmful way.

Some EMF protection devices emit repetitive frequencies, including supposedly beneficial frequencies like the Schumann resonance, or Solfeggio frequencies. They will repeat one frequency, or one sequence of frequencies, over and over again. Some healing devices, like PEMF machines, will also do this to stimulate healing with a short term use. We don’t recommend exposing your body to repetitive frequencies for too long. You may see benefits at first, but over time, the body can develop a tolerance, resistance, or even an allergy to the repeated frequency. In terms of how it affects your body, the repetition of one frequency is like hitting the same button over and over again, exhausting the body in a certain way, while “under-stimulating” your body in other ways. Think of it like consuming too much of one nutrient or mineral, which eventually creates an imbalance and requires other nutrients to balance the body out.

Repetitive frequencies are thought to be a large part of the harm from manmade EMF sources. The information from your cell phone and cell towers is transmitted on a carrier signal of a single frequency. This frequency, for example the 2.45 GHz from your Wifi router, is stimulating your body in a very specific way, 24/7. This is not natural, and we are not designed to deal with a constant barrage of repetitive frequencies, since they do not exist in nature.

Not only is the repetitive aspect of the frequency and amplitude having a negative impact, these carrier signals (or information carrying radio waves) contain the information of the text or voice that is being sent, which is not coherent when it reaches the body. Energy fields in nature are coherent and beneficial to the body, so when the body is bombarded with chaotic signals, it goes on the defensive.


Blushield Active EMF Protection – Amplifying Nature’s Native Frequencies

We are surrounded by natural frequencies, and have been since the beginning of our existence. These frequencies of nature are infinitely varied, and nothing in nature will ever repeat in exactly the same way more than once, because everything in time and space is always moving and changing. We need these frequencies for our health.

Sadly, most of us live in population dense cities with very little natural elements around us. We are around buildings, cars, and wireless communications devices all day, and our lives are sorely lacking in dense forests, waterfalls, the ocean and beach, and the freshly charged, negative ion rich air of high mountain environments. There is still the background Schumann resonance frequencies (which are actually changing and not a fixed frequency), but our manmade devices are so pervasive that these subtle background frequencies become mostly drowned out, as far as our bodies’ ability to sense them.

The idea and purpose of Blushield is to mimic the frequencies nature emits, but to do it in an active, powered way, amplifying natural frequency patterns so our bodies can “hear” them over the manmade EMFs. As long as the Blushield device you are using is strong enough for your body to hear it over the combined total of repetitive manmade EMFs around you (which will be unique to your situation), your Blushield will emit the dominant signal in your environment, and your body will “hear” or “tune into” this signal and begin to resonate with it.

This process of your body preferentially entraining to a dominant frequency stream that’s more biocompatible is called “sympathetic resonance”.

This doesn’t mean the EMFs go away, just that your body stops paying attention to them and reacting to them. When the body notices the harmful EMFs, it treats these unfamiliar and repetitive frequency patterns like it would treat an actual physical invader (like a virus or bacteria), and mounts an immune response to them, in an effort to attack and defeat them. The problem is, there is nothing physical there to attack and defeat, so the body exhausts itself continuously trying.

This immune system overreaction to repetitive frequencies is the primary reason that EMFs are harmful. If we had another frequency stream available to entrain to, one that was biologically coherent and similar to the way our bodies are designed, we would entrain to it like a tuning fork. Or like tuning into a different radio station. The other stations still exist, but we can’t hear them anymore, since we have turned the dial to a different station. What is interesting is that the biology demonstrates that the body is no longer negatively impacted by the EMF in the environment when Blushield is in operation and once the person is fully entrained. So it is not just ignoring the EMF, the body is actually harmonizing and optimizing its biofield, which is what a lot of these passive devices are claiming to do.

Blushield is an active, powered device that utilizes cutting-edge microprocessor technology. The nature-based, infinitely varied multiple waveform algorithms are programmed into the microprocessor. This extremely complex pattern is sent through a circuit to light-emitting diodes (which can produce scalar fields through photon emission), which encode the waveform patterns onto a scalar carrier signal that radiates hundreds of feet outward in an invisible sphere.

Because Blushield uses a scalar/longitudinal carrier signal, it is highly bioactive. The encoded frequency algorithm emits multiple waveforms at the same time, each conforming to patterns that occur in nature, such as the Phi ratio. The frequencies themselves are all within the human responsive range, which is a range of frequencies that occur in nature that are harmonious with biology. The multiple waveforms overlap in a way where they will never repeat in exactly the same way twice, with the same combination of frequencies at the same amplitude. This ensures that the body never develops a tolerance or resistance to the frequencies, so we will remain attuned to Blushield for as long as the device is plugged in or turned on.


Which EMF Protection Strategy is Right for You?

To wrap it all up and help you apply this to your unique life situation, how can you know which protection strategies will give you the most mileage and results?

We recommend basing your EMF protection on a combination of reducing EMF exposure in reasonable ways, and the appropriate strength Blushield device(s) for your living situation and needs. The active, powered nature of Blushield makes it far more powerful than any passive device, and it also stands out among active devices on the market with its revolutionary scalar microprocessor and infinitely varied frequency output based on natural patterns that have been with us as humans since the beginning of our time here.

If you want to add anything on top of that, go for it! We find that Blushield doesn’t seem to conflict with or negate other devices and approaches, and can be used in combination with most of them with no ill effect. In fact, if there are other frequency generators or devices being used, it will likely fill in the gaps or balance the body to anything that may not be in resonance or coherence with your body.

You can use Blushield with shielding materials, which will protect you from the scalar component of the harmful EMFs that travels through the shielding materials.

You can use Blushield with grounding/earthing sheets and mats, where Blushield could protect your body if the grounding influence is causing ambient EMFs to “ground” through you, which could potentially increase your EMF exposure.

You can use Blushield with stones and pyramids, and passive devices that emit subtle healing substances and frequencies into your environment. In this case, Blushield could be seen as your basic EMF protection, and any passive devices that actually work may add some energetic perks on top of that.

You can use Blushield along with PEMF and microcurrent healing devices, where it can negate any stress that may be caused by repetitive transverse frequencies these devices can emit, while still allowing your body to benefit from the targeted healing influence of these therapeutic style devices.

To find out which stationary home device and portable Blushield devices would be the best choice for your living situation and needs, please read our Blushield Product Guide. We have several models of home devices and portables, each designed for different situations and exposure levels.

Solar Power Systems: How To Reduce EMF Exposure Risks

The electricity that we use to power the devices in our homes and buildings can be produced by a variety of sources. Natural gas, coal (burned to make steam), heat from nuclear energy, hydropower (moving water) and wind (moving air) can all create motion to spin a turbine, which is connected to a generator. The movement created by any of these sources spins the rotor in the generator, pushing electrons along a conductive coil, which interact with magnets to produce alternating current (AC) electromagnetic fields. This electricity travels to our homes via the power grid, and is a resource produced far away from our homes, which we depend on for most of our household routines.

Since the invention of solar power systems, which have become more economically viable over time, we now have the option to produce our own electricity directly from sunlight. This can decrease our dependency on the external power grid, and even reduce or eliminate our electricity bill. Most of us have plenty of sunlight where we live, at least during the warmer seasons, so in recent years as the components of solar power systems have become more affordable, this has become a viable option for home electricity.

The sun is a steady and reliable resource that most of us have direct access to. While the upfront cost of the components are a significant investment, a home solar power system can be economically advantageous in the long run.


How do solar power systems work to generate electricity?

With solar power systems, sunlight directly excites electrons held in crystallize materials like silicon, generating direct current (DC) electricity. This occurs on the surface of solar panels, also known as photovoltaic (PV) panels, which are placed in sunny areas like rooftops or open fields. The term photovoltaic refers to the generation of electrical voltage when photons of light come into contact with a material.

This DC electricity needs to be converted into AC to be usable by the electrical systems in homes and buildings – this is done with a device called an inverter. Inverters take the DC electricity and rapidly switch the direction back and forth, creating an “alternating” current – AC electricity. The inverter also ensures that the resulting AC matches the grid’s voltage, frequency and phase (in the United States it’s usually 120 volts at 60 hertz), to safely integrate the electricity into the grid. The end product from the harvest of solar energy generates electricity that’s identical to what’s produced by a generator powered by natural gas, coal, nuclear, hydro or wind.


Grid-tied versus off-grid solar systems – pros and cons

If a home solar power system is tied to the grid, this has several benefits and also some downsides. Batteries are by far the most expensive component of a solar power setup. With a grid tied solar system, you don’t need a battery to store the solar energy for use at night or during rainy or cloudy days – your solar power is fed directly into the larger electric grid, giving you an electricity “credit” that you can use later when it’s needed, automatically balancing out the fluctuating and unpredictable availability of sunlight. A grid tied solar system is far more convenient and flexible.

The main downside of grid tied solar power systems is that you’re still dependent on the electrical grid, even though you’re reducing your overall electricity cost by feeding your excess power into the larger grid. If the grid goes down, your power goes out, unless you have a generator as a backup. Another downside is that you’re almost certainly required to use a smart meter (unless your local area allows you to opt out), to accurately keep track of the electricity you’re sending to the grid and receiving back from it. Smart meters produce high levels of wireless radiofrequency (RF) radiation, and contaminate your home wiring with dirty electricity.

An off-grid solar system, on the other hand, is a closed system designed to produce all the electricity needs for a given location. This design requires much more forethought and careful planning, with enough solar panels to harvest sunlight energy for all household needs, a large enough battery bank to store power for use in times of the year with limited sunlight, and usually a backup generator for “worst case scenario” situations. It also necessitates more discipline and careful timing of electricity use for those living at that location. Another downside of an off-grid system is that since all power is produced at the location of use, you could be exposed to higher levels of EMFs from the storage batteries and the potentially larger quantity of total equipment used by the system. The benefits of a well designed off-grid solar system are energy independence from the external power grid, and not needing to use a smart meter.


Solar power system EMF exposure concerns & mitigation strategies

Both types of solar power systems will expose you to some level of EMFs, but understanding the EMF hotspots generated by each type of system will give you clarity about how to reduce and mitigate these risks. Solar panels produce a small amount of low voltage direct current (DC) electricity, and since they are usually placed a good distance away from living areas, the panels themselves aren’t much of an EMF concern.

The wiring that runs from the panels to the inverter and/or battery emits EMFs, and if you’re designing a solar setup, one way to minimize EMF output from the wiring is to ensure that all the wires – positive, negative, neutral and ground – are run side-by-side, tightly paired or twisted together. If the wires are run separately, inches or feet apart from each other, a strong magnetic field will be created in the space between the wires. When they’re close together, the magnetic field is basically canceled, reducing ambient EMF readings.

Every solar power setup uses an inverter to switch the DC power from sunlight into the AC power used by the grid. Inverters create dirty electricity as a byproduct of this conversion, which enters your home wiring. However, it’s important to realize that even with a conventional power system (and no solar setup), you are still exposed to dirty electricity from devices within and outside of your home. Dirty electricity, a term that describes voltage transients, fluctuations or anomalies that “dirty up” an otherwise smooth and “clean” sine wave, is an issue for almost everyone who lives a modern, technology-rich life.

The difference in EMF exposure between grid tied and off-grid solar power systems is the presence or absence of a battery, and the presence or absence of a smart meter. Off-grid systems must use batteries, and grid tied systems almost always use smart meters.

Solar batteries produce static magnetic fields, with the highest readings right next to the battery, quickly dropping down to zero as you move further away. The extra exposure from a solar battery bank can be mitigated by having a dedicated power room or shed that’s separate from the house or living area where humans and pets spend time. Your inverter can be in this room, as well, preventing exposure to the EMFs directly around the inverter.

The EMFs from a smart meter cannot as easily be mitigated by distance. If the meter is further away from the house, on the outside of a dedicated power shed, the radiofrequency (RF) transmissions the meter produces by sending and receiving data to and from the power company will be occurring further away from people, which will reduce wireless RF exposure to lower levels. However, the smart meter will still contaminate the electrical system with dirty electricity, on top of the dirty electricity that’s already being added to your home wiring by the inverter.

We also need to touch on the different types of inverters used in solar power systems: string inverters and microinverters. Microinverters are small inverters placed underneath each panel in the solar array, designed to convert DC energy from the panel into AC at the site of energy production, each inverter controlling a separate panel. String inverters are installed at the end of a string of panels, controlling them all as one, and are usually further away from the panels, on the ground in a main solar system control area (like a power shed).

Microinverters can optimize energy production since they treat each panel as a separate system. String inverters group a whole string of panels together, where the limitations of one panel could end up affecting the entire string: for example, if one panel is in the shade, or is losing efficiency due to age or corrosion, that affects the power production from the whole group. If each panel is controlled separately with microinverters, the high functioning and/or high sun exposure panels will not be limited by panels that may be converting less sunlight into power at any given time. In installations with partial shading or panel mismatch, this can result in higher total energy production over the lifetime of a system using the same number of panels.

Using microinverters under each panel is generally considered safer, since it immediately converts DC to AC – DC power can be a bigger fire hazard under compromised conditions, whereas AC is easier to control. However, that means the wiring on your roof would be running AC power, already carrying dirty electricity through the wires, potentially exposing you to more EMFs if any of your living spaces are close to the roof. Microinverters are also more costly than string inverters.

One last note about inverters and radiofrequency (RF) radiation: if you use an EMF meter (like the Trifield meter) to measure the EMFs coming from your inverter(s), you will likely notice a reading categorized as “RF”. Radiofrequency or RF emissions are commonly assumed to only come from wireless communication devices that use frequencies in the megahertz (MHz) or gigahertz (GHz) range to transmit data wirelessly from one place to another with aerial antennas. However, EMF meters will interpret any frequency in the low kilohertz (kHz) range and above as radiofrequency.

In the case of inverters, frequencies in the kHz-MHz range are produced as a byproduct of high-frequency switching electronics, in the form of a localized noise field. These emissions are not transmitted via antennas and typically diminish rapidly with distance, often approaching background levels within a few feet of the device, similar to other localized electric or magnetic field sources.


Eliminate dirty electricity concerns by cleaning up the sine wave

Dirty electricity, or high frequency voltage transients, are bad for the health of your devices and appliances, generating high frequency spikes that wear out electronic equipment, reducing their longevity. This high frequency “line noise” is also bad for your health, being potentially linked to cancer, diabetes, cardiovascular disease, chronic stress, brain and mood disorders, obesity, asthma, and electro hypersensitivity (EHS).

Whether you’re concerned about the effects of dirty electricity produced by your solar power system’s inverter, the smart meter that a grid tied solar system necessitates the use of, or even just dirty electricity produced by the regular electrical grid with its smart meters and devices/appliances that utilize power in complex ways, there is a way to “clean up” the sine wave.

The SineTamer device, which is wired into your main breaker panel, removes all the excess voltage transients and spikes from the sine wave, by absorbing the excess and converting it to heat to be dispersed through the ground wire. Unlike the capacitance-based, plug-in dirty electricity filters that are widely available – which shunt the dirty electricity onto the neutral line, creating a strong magnetic field with equal or even greater health harms – SineTamer removes the threat completely.

The SineTamer also acts as a surge protector, which is an important component of a solar power system.


Comprehensive EMF protection for a variety of electromagnetic threats

While the SineTamer is an excellent solution for cleaning up the sine wave and therefore reducing the effects of dirty electricity, you still need to protect yourself from the ambient electric and magnetic fields produced by a solar power system, as well as wireless radiofrequency radiation from a variety of sources: smart meters, Wifi routers, Bluetooth, cell phones, nearby cell towers, smart appliances, and more.

One additional concern that some people have is living near a commercial solar power plant, which can expose anyone living nearby to EMFs that are orders of magnitude higher than a home solar power system. This situation requires considerably more protection than the relatively moderate electric, magnetic and radiofrequency fields that a home system would normally expose you to.

Blushield home and portable EMF protection devices offer comprehensive protection from all these radiation sources. There are different models designed for differing levels of EMF exposure, whether you live in a rural area or small town, suburban area or medium city, or even a large city or metropolitan area.

If you have a solar power system with a smart meter or battery bank close to your living area, or if you live near a commercial solar production facility, a strong Blushield model like the C1 Ultimate Cube, EVO Cube or EVO Pyramid would be an excellent choice for optimal protection.

If your home solar power system is designed with plenty of distance between your living area and the strongest EMF sources – the inverter, battery and smart meter – one of our low to moderate EMF exposure models like the Phi 02 Plugin, Phi 03, or B1 Premium Cube would likely suit your needs well.

If you also need protection when you leave your house, from the EMFs in your vehicle, cell towers, and exposure sources at other locations, a Blushield portable device will ensure that you stay in your “protective bubble” no matter where you go and what you’re exposed to.

Solar power systems can be a useful and beneficial upgrade to conventional electrical systems, as long as you understand the unique EMF risks and how to mitigate them.

In a story we have been following for months, the residents of a small Alaskan island town who have been fighting against a proposed cell tower placement in a residential area were recently given the best news they could hope for, making over half a year of hard work worth it: the proposed cell tower was officially rejected by a court decision this October.

Studying the details of this case should help other local municipalities fight proposals for inappropriately placed cell towers in their area, and the precedent set by this case could strengthen other legal battles that are fought on similar grounds.

How did Sitka, Alaska win this case, when the Telecommunications Act of 1996 only allows local governments to reject new cell tower placements under very specific conditions?

Sitka is a remote island town of roughly 8,400 residents who take pride in the spectacular scenery, wildlife and tight-knit neighborhoods. Local wireless communications provider Tidal Networks had their sights set on a building location on a hill right above a residential neighborhood on Nancy Court, in an area with R-1 residential zoning, within 150 feet of homes. They insisted that the cell tower would need to be a massive 120-foot monopole to provide the level of coverage they were targeting, even though the R-1 zoning laws restrict the height of cell towers to only 35 feet, to protect local aesthetics and property values.

Another major issue is that the proposed cell tower location is in a zone with considerable landslide risk. This neighborhood is located at the edge of town, on the base of a hill. Landslides at this location are a distinct possibility, and far more likely if the soil is disturbed through construction of a large cell tower. Not only would the addition of a cell tower destabilize the ground in this area, making landslides more likely, but a strong landslide could cause the cell tower itself to collapse. If this occurred, the tower would fall towards the neighborhood, and local residents would be in danger for not just their property, but their lives.

Aesthetics are an important subject for local residents, who specifically built their houses in this location for the breathtaking natural views of nearby mountains, thick trees of the temperate rainforest, and the ocean view below.

As soon as the local government notified residents of the planned tower, many of them became alarmed and began researching the potentially harmful health effects of living so close to a radio frequency radiation emitting cell tower. Although the Telecommunications Act of 1996 specifically prohibits the rejection of cell towers based on the environmental effects of radio frequency emissions (which is absurd, as this should be a valid concern and argument in itself), fortunately Sitka had several other solid arguments to lean on, which were supported by the Act.

Tidal Networks filed for a variance (a zoning exception) to the 35-foot tower zoning restriction, arguing that the surrounding trees would block too much of the tower’s signal. Even though the Sitka Planning Director initially recommended that the variance be granted, it ended up being denied the first time, in April, due to a lack of supporting evidence. The telecom provider did not give up, and appealed their request, but it was eventually denied once more for several reasons. R-1 residential zoning restrictions only allow cell towers up to 35 feet in height, and variances are only granted if the tower would serve a clear need in the community. Sitka is already considered to be well serviced by wireless network providers, including accessible plans for low income residents, so the Tidal Networks tower would not be filling a need that was previously absent.

Another unusual aspect of the proposal that contributed to its denial by the court is the tower would have no wired fiber optic ground connection that would allow other local providers to place antennas on it, but would exclusively connect with satellite internet providers like Starlink. This would limit the usefulness of the tower as a placement structure for other antennas, and the company provided no cost analysis plans for building out a wired ground connection, now or in the future.

One of the telecom’s arguments for being granted this tower location is that they investigated 129 different sites in the Sitka area, and the Nancy Court location was the only one providing adequate coverage. It turns out that many of these 129 sites were private property, and property owners refused to sell their land to the telecom. Since Tidal Networks intended to use grant money for this tower, and the grant required that Tidal has ownership over their building locations (instead of just leasing the land), the property owners’ refusal to sell automatically ruled out many of the other sites.

The Court Decision text states, “Public comments and letters were uniformly opposed to the variance based on concerns that construction of the tower would lower the value of nearby properties, would expose nearby residents to potentially dangerous radio emissions, destabilize landslide prone slopes in the area, and negatively impact aesthetics and land values in the area.”

The successful rejection of this tower was fully due to local residents banding together and taking quick and decisive action, both in seeking out legal assistance, as well as speaking out about the tower through letters and at local meetings throughout the entire process. Early on, as soon as residents were informed of this tower proposal and became cognizant of its potential dangers, they formed Sitka For Safe Tech, and contacted Children’s Health Defense attorney Scott McCullough, an expert attorney with extensive experience with cell tower related cases. This early action was vital to their success.

It is vastly easier to prevent a cell tower from being placed while in the early planning stages, than to cause a cell tower to be removed after it’s already been built.


Why is it so hard for local governments to reject cell towers?

The court decision document for the Sitka case included an insightful section that illustrates the heart of the problem of why rejecting cell towers is so difficult:

“Proposals to build wireless telecommunication towers invariably raise thorny issues for local zoning authorities. Much like high voltage power lines, highways, and airports, almost everyone uses the services made possible by these towers. Indeed, given the number of people and businesses who depend on the availability of reliable wireless networks, these towers are a necessity of modern life. Correspondingly, however, nobody wants a telecommunications tower constructed close to their home. If the decision to build these towers was effectively handed over to the owners of nearby properties, it seems a safe assumption that few would ever be built.”

This paragraph illustrates a classic conflict between the needs of the public and the values of the private. The document then follows up by quoting the Telecommunications Act of 1996, and how Section 704 (which is an amendment to Section 332 of the original Communications Act of 1934) intends to balance the scales between the values of the private individual and the benefits desired by the public:

“For this reason, Congress has enacted provisions within the Telecommunications Act, that limit the ability of state and local governments to deny applications for the construction of “personal wireless service facilities.” These provisions, which have been codified at 47 U.S.C. §332(c)(7)(B), provide as follows:

(i) The regulation of the placement, construction, and modification of personal wireless service facilities by any State or local government or instrumentality thereof

(I) shall not unreasonably discriminate among providers of functionally equivalent services; and

(II) shall not prohibit or have the effect of prohibiting the provision of personal wireless services.

(ii) A State or local government or instrumentality thereof shall act on any request for authorization to place, construct, or modify personal wireless service facilities within a reasonable period of time

(iii) Any decision by a State or local government or instrumentality thereof to deny a request to place, construct, or modify personal wireless service facilities shall be in writing and supported by substantial evidence contained in a written record.

(iv) No State or local government . . . may regulate the placement, construction, and modification of personal wireless service facilities on the basis of the environmental effects of radio frequency emissions to the extent that such facilities comply with the Commission's regulations concerning such emissions.

To the extent a local government denies an application to build a personal wireless service facility in violation of these provisions, the applicant may seek an injunction in federal court that overturns the denial.”

Overall, these rules provide a reasonable compromise between private and public needs. The main exception is subsection (iv) that prohibits the rejection of cell towers on the basis of “the environmental effects of radio frequency emissions”, which could also be construed to include health effects. At this time, as studies continue to pile up demonstrating harmful health effects (on humans, animals, trees, insects and more) from radio frequency radiation, there is a major movement towards overturning section 704 of the 1996 Act, and specifically subsection (iv).

The most vocal source of opposition is 704 No More, an initiative of the Children’s Health Defense, who have been instrumental in helping local municipalities battle inappropriate placement of cell towers. The 704 No More initiative seeks to educate people about the need for an environmental and health based defense against cell tower placement, with the intention to eventually overturn or revise Section 704.


FCC seeks to override local zoning restrictions with new rule – don’t let them!

Ironically, or perhaps intentionally, the FCC is currently seeking movement in the opposite direction. From FCC’s Docket 25-276, a Notice of Proposed Rulemaking is attempting to “streamline” tower placement by eliminating “regulatory burdens imposed at the state and local level”. Even with the very reasonable rules already stated in the 1996 Act, which mostly favor the telecoms and not local governments, that is not enough for them. They want to “expedite, eliminate and simplify permitting burdens”, which they argue are limiting economic development, job creation and energy production.

We don’t see what the problem is. Aren’t there enough cell towers already?

Also, it is perfectly reasonable to require a large build-out of infrastructure (like a cell tower) to go through a full permitting and approval process, and not to be granted special benefits to skip over any part of a full assessment for appropriate placement and planning at the state and local level.

Local municipalities already have limited power to prevent cell tower placement, and must base their rejection on very specific arguments (as outlined in the 1996 Act above). If a local government cannot listen to the concerns of the people they serve, and act as an intermediary between the needs of their citizens and the desires of large corporations (who may not truly have the benefit of the people in mind, over their own profits), then what fail-safe do we have to prevent unchecked growth that may be motivated by greed?

It is true that private values and public benefits can sometimes seem to be in conflict. This should be where the “scales of justice” can step in, assess the nuances of an individual situation, and decide on a solution that is truly fair. To do this successfully, the appropriate laws must be in place to act as a basic framework for these real-time decisions to be made in the courts. We cannot completely skew the law in favor of large corporations, and leave no recourse for local areas to defend the needs of their people.

If we allow this, there would be nothing left to limit and safeguard against the greed of money-hungry corporations who aren’t serving a real need to “underserved” areas, and are mainly concerned with propping up as many cell towers as they can get away with.

The FCC Proceeding is titled “Build America: Eliminating Barriers to Wireless Deployments”, Docket Number 25-276.

A website titled Preserve Local Control has been created as a platform to spread the word about this proposed rule, so that we can submit comments directly to the FCC’s docket within a time-sensitive window.

What did Sitka, Alaska do correctly that other local areas can learn from?

Let’s go back to the successful Sitka case to close this out, and summarize what Sitka did right that other local areas fighting proposed cell tower installations could learn from.

It’s true that part of their success was situational: the Tidal Networks cell tower proposal was almost doomed to fail, due to their bravado in assuming they could take advantage of the inertia of the system and be granted an easy variance to the zoning regulation on tower height. They were also lazy in their planning, with an insufficient argument as to why they needed a 120-foot tower (instead of a more gentle compromise of a tower height somewhere between 35 and 120 feet). Another aspect of the denial was due to the telecom’s inability to show that its proposed tower “would not be materially detrimental to the public welfare or injurious to the property nearby parcels.” This likely refers to both the landslide risk of the area, as well as the tower affecting aesthetics and property values, both of which are strong grounds for a rejection that are well supported by the 1996 Act.

However, even with all its flaws, this tower proposal would have likely been approved seamlessly if local residents didn’t take a stand against it.

The court’s verdict also stated that 47 U.S.C. § 332(c)(7)(B) does not apply to the tower proposed by Tidal Networks, because it would only provide services for their fixed wireless broadband internet service subscribers, and not wider and more generic commercial mobile services “available to a substantial portion of the public” that the Act provides protection for.

Even though we currently cannot argue for the rejection of a cell tower on the grounds of environmental or health effects of RF radiation (which we are hoping will change!), there are still other arguments we can make that are strongly valid under the current laws.

The most important thing is to act quickly – as soon as you hear about plans for a proposed cell tower in your area, seek legal counsel from an experienced attorney (like Scott McCullough) to determine if your area has solid grounds on which to reject the tower placement. Since the 1996 Act requires that local governments must “act on any request within a reasonable period of time”, this means you cannot delay taking action, because your local area is required to respond as quickly as possible.

Downplayed Dangers: The Missing EMF Conversation in the MAHA Report

First let’s start with the good news:  the recently published Make America Healthy Again (MAHA) report is the first official acknowledgment by the executive branch of the United States government that electromagnetic fields (EMFs) pose health risks even below the FCC exposure level guidelines.  In itself, this is a groundbreaking step towards broader public awareness and action steps to protect humans, animals and the environment from ever increasing EMF exposure from a wide variety of manmade sources.

However, there has been much criticism about how the report significantly downplays the harms of EMFs, and made statements that were watered down, misleading and even erroneous, to lead the public to believe that the potential problem isn’t nearly as bad as it actually is.

Let’s break it down to see what the report does say, and what it leaves out.

The MAHA Report, published on May 22nd, 2025, is a very extensive and detailed 73-page document.  The report focuses on the effects of ultra processed foods, environmental toxins, the childhood vaccination schedule, overmedicalization, a sedentary lifestyle, and corporate lobbying, considering all of these to be heavily influential factors in the chronic disease epidemic in the United States, especially in children.

The contents are groundbreaking and significant, and could create a wave of positive policy change that supports human health.  The majority of subjects this report addresses have been considered taboo in the past, and are concerns of a growing percentage of the population that have been continually ignored by the government and their corporate lobbyists.  These lobbyists represent the industries that control the widespread acceptance of these harmful lifestyle factors, which strongly influence our culture and habits, to all of our detriment.

The report points out that over 40% of U.S. children have at least one chronic health condition, making this generation of children the sickest in American history. These trends have consistently worsened each year, according to the report, “posing a threat to our nation’s health, economy, and military readiness.”

In particular, childhood cancer, obesity and autism have increased by alarming rates since the 1970s. It is predicted that children growing up today are likely to have shorter lifespans than their parents.

Health & Human Services (HHS) Secretary Robert F. Kennedy, Jr., calls this report a “diagnosis”, and says “the prescription will follow in 100 days”, likely sometime in August.

This report is truly the first of its kind, and we want to give it the credit that is due, especially if the action steps taken based on this report’s findings are truly enough to result in significant positive change.

Unfortunately, although EMFs were mentioned in the report, it was only one brief paragraph that touched on the potential harms – and the dangers were disappointingly downplayed.

EMF section of the MAHA report misses the mark

Throughout the otherwise comprehensive 73-page MAHA report, which extensively explores several influences and elements considered harmful to children today, only one short paragraph was dedicated to EMFs, on page 44.  It was tucked into a broader section addressing environmental chemicals, but many critics say that there should have been a full section of the report dedicated to EMFs as one of the main drivers of chronic health issues in children.

This is the full statement concerning EMF exposure in the MAHA report, along with several numerical citations:

“Electromagnetic Radiation (EMR): an exposure due to the proliferation of cell phones, WiFi routers, cell towers, and wearables. Some studies have linked EMR exposure to reduced sperm counts and motility but not quality. The NIH’s National Toxicology Program identified “clear evidence” of DNA damage and increased cancer risk in rats. However, a recent systematic review of over 50 studies found low to inadequate evidence on impact in children and called for more high-quality research.”

In comparison with the dedicated work that Robert F. Kennedy, Jr. himself, who spearheaded the MAHA report, has done to bring awareness to the imminent and extensive dangers of EMFs, the casual and light nature of this paragraph is both confusing and frustrating.  There is much speculation that this statement was written or heavily doctored by a telecom industry representative infiltrating the government with corporate lobbying money – which is quite ironic, considering that the report devotes a whole section to the serious issue of corporate lobbyists and their influence on public health policy.

This paragraph selectively cites a 2022 systematic review that found “low to inadequate evidence of impact on children”, calling for “more research”, which is a well known delaying tactic by polluting industries of all types.  The report ignores larger, more recent and incriminating study reviews, including a systematic review from the World Health Organization (WHO) from 2025 that concluded there is “high certainty” evidence that cell phone radiation causes two types of cancer in animals.  There are several more recent study reviews, as well as an extensive body of well designed and executed scientific research, that the MAHA report completely fails to mention.

The EMF paragraph also contains an erroneous statement about the effects of EMFs on sperm quality.  It stated that sperm counts and motility were negatively affected by EMFs, but not sperm quality. However, in the medical field, sperm quality is assessed by looking at a combination of several factors, including sperm motility.  If sperm motility was negatively affected by EMFs, that automatically means overall sperm quality had to have been affected by EMFs as well.

Dr. Robert Brown, a diagnostic radiologist with more than 30 years of experience, points out that the statement doesn’t make sense, and was likely added by someone without a background in the biomedical research field.

“By affecting sperm counts and motility, sperm quality is affected,” Brown pointed out, then goes on further to state, “I wonder who added this erroneous phrase, and find it interesting that it was added in the same document in which a separate section discusses corporate capture and the revolving door.”

The report’s silence on the influence of corporate capture as applied to EMF dangers definitely raises questions.  A 2021 court ruling in the Environmental Health Trust vs. FCC case declared the FCC’s decision not to reevaluate their 1996 wireless exposure guidelines to be “arbitrary and capricious,” and an order by the judge compels the FCC to revise these grossly outdated guidelines, which they have still failed to do several years after the ruling.

It seems quite clear that the telecom industry and the governmental branches that presumably regulate this industry are using tactics of delay and dismissal to avert the public’s eyes to the problem, even while other timely public health issues are finally being addressed in the MAHA report.

Multiple recent bills by the current administration have focused on expanding wireless proliferation even more, including a newly approved spectrum auction in the 600 MHz range, as well as a new bill proposing to grant the FCC even more authority:  Section 40002 of HR 1 would trigger provisions that allow telecoms to place an unlimited number of antennas on existing antenna structures without notice or approval.

Here is a letter you can print out and send to your local officials, urging them to reject Section 40002 of HR 1 on the argument that the FCC still hasn’t complied with a 2021 court order compelling them to update their outdated wireless exposure guidelines from 1996:

Children’s Health Defense fights back with the 704 No More initiative

An organization dedicated to protecting children from harmful environmental and medical exposures, Children’s Health Defense (CHD) is committed to ending the rise in childhood health epidemics by holding corporations and regulatory agencies accountable, and pushing for stronger safety standards.

One of CHD’s recent initiatives directly addresses the weak link in the law that is responsible for allowing telecoms to get away with unchecked placement of cell towers in populated areas, especially in neighborhoods and near schools:  Section 704 of the Telecommunications Act of 1996.

This law prevents local regulation of wireless infrastructure based on health and environmental effects, and is widely considered to be unconstitutional, because the law deprives states of their traditional police powers designed to protect the health and welfare of their citizens.  The 704 No More initiative seeks to overturn this law, restoring the legal ability of local governments to have a say in the placement of cell towers within their communities.

Section 704 undermines public health, environmental protections, and individual rights.  It allows for the enforcement of the FCC’s outdated RF radiation guidelines, ignoring mounting evidence of harm, particularly to children.

As one of the causes Blushield supports with monthly donations, a portion of your Blushield EMF protection purchase is donated to support the 704 No More initiative, as well as CHD’s Stop 5G initiative.

704 No More is a powerful initiative that gets right to the heart of the issue, as Section 704 currently grants legal protection to the telecom industry from any individual and local community seeking to challenge the inappropriate and dangerous placement of cell towers near residences and schools.

The initiative argues that this legal framework must be dismantled because:

  • RF radiation below FCC limits has been shown to harm children’s health and the environment.
  • Children harmed by RF radiation exposure are left without remedies or compensation.
  • FCC guidelines are outdated, do not take children into account, and fail to consider current scientific evidence.
  • Excessive FCC authority overrides local control and judicial oversight.


Led by expert attorney Scott McCollough, the actions being implemented by 704 No More include strategic litigation, public education, grassroots mobilization, and legislative advocacy.

Updating FCC standards and curtailing federal overreach are critical steps toward protecting our children’s well-being. By restoring local authority and individual rights, we can build a healthier, safer future for our children.

Frequently asked questions

Invisible forces are part of modern life, but their impact doesn’t have to define you. Blushield works quietly in the background, supporting a more stable, balanced internal state so you can focus, rest, and perform at your best.

What does a Blushield device actually do?

It doesn't block or shield EMF. Instead, Blushield is designed to support the body's natural response to everyday electromagnetic exposure. By focusing on biological support rather than altering environmental signals, it takes a different approach to EMF protection.

Which device is right for me?

Plug-in units (Premium, Ultimate, Phi) cover your home. Portables cover you when you leave it. Most people start with one of each: a plug-in for the house and a portable for travel, work, and the car. If you're not sure, use our Find Your Device tool or message us.

What's your return and warranty policy?

30-day limited money-back guarantee on every device (restocking fee applies - see our full return policy). Stationary and portable units carry a 1-year warranty. If anything extends past that, contact us.

Do I still need it if I have low EMF readings at home?

Yes. EMF meters measure intensity, not biological impact. Even low-level exposure from Wi-Fi, Bluetooth, smart meters, cell towers, and nearby homes accumulates 24/7. Blushield works on the body's response, so it helps regardless of what a meter reads.

How long until I feel a difference?

Some people feel calmer or sleep better within the first night. For others it's a few weeks of gradual change - better focus, deeper sleep, and less fatigue. A small number notice a short adjustment period as the body recalibrates. Everyone responds differently, so give it time to become part of your daily environment and let the benefits build naturally.

Is there science behind this?

Yes. Blushield is built on decades of research into how the body responds to coherent vs. incoherent electromagnetic signals. We have independent studies, HRV data, and live-blood analyses on our Science page. We don't make medical claims. We point you to the data and let you decide.
