The SPIRO® SQUARE is an electromagnetic radiation shielding system designed to filter out emissions (low and high frequency) associated with WiFi routers, WiFi extenders, video game consoles, and computers. This product has a range of action of 8 feet (2.4 meters) radius and has 2.3 times the power of the SPIRO® CARD, allowing it to filter out stronger emissions. To use it, simply place the product near the devices or close to you, such as at your workstation or in your vehicle. Laboratory tests have shown that this electromagnetic protection system is fully compatible with electronic and wireless devices, optimising their operation, connectivity and extending their useful life.
