C1 Ultimate Cube
The C1 is designed for those living in densely populated areas, and has more than 120 to 450 cell towers and 300 to 1,000 or more antennas within 3 miles. It provides more than twice the protective strength as the B1 Cube, and 25% larger of a coverage area, reaching 120 meters (393 feet) in all directions. The case is a highly durable aircraft grade gray alloy, with a unique geometric cube design.

The C1 Ultimate Cube is one of our most powerful stationary EMF protection models, and is designed for those living in densely populated areas, or anyone who needs maximum coverage area.
Providing an impressive coverage area of 120 meters (393 ft) in all directions, the C1 is great for large homes or situations where one requires protection far outside of their dwelling. The C1 base protection strength is about 20% stronger than our U2 Premium Ultra model. The C1 comes in a gunmetal grey alloy case that can be table mounted via a 3M soft pad. This Ultimate Cube model is suitable for use in high 5G areas. Its effectiveness for 5G is unparalleled to anything on the worldwide market.
Our C1 Ultimate Cube emits a dual band scalar signal, where two different frequency sets are produced that operate in tandem. You will notice that your C1 emits a solid blue light most of the time, but every half minute or so, the light will flicker for a couple of seconds. These two alternating fields keep the body adaptable and dynamic, ensuring a continual response to the field even after many years of use.
Our dual band models are designed to protect the body from more intense forms of EMF, like close range 5G, and also to help it regenerate more quickly from any exposure that may still be affecting the body.

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.
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.
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.
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.
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.
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.
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.
