Blushield is an active EMF protection technology designed to protect users from the health effects of man-made electromagnetic fields from mobile phones, smart meters, Wi-Fi, 3G, 4G, 5G and all other sources of EMF. 
 
The new Blushield C1 Ultimate Cube is the strongest Blushield protection to date, with a 120-meter radius in all directions (240-meter diameter) coverage area. 
 
Further enhanced with Blushield's proprietary formula, the C1 Ultimate Cube is stronger than the Blushield Premium Cube and Blushield Premium Ultra and is recommended for high-density environments with high to extreme levels of EMF, including homes with solar panels, smart meters, close to antennas, smart meter grids, substations, high-rise apartments and workplaces.
