How many square meters do EarthCalm Home & Office protection products cover?

Both our Home & Office protection systems are unique in that they cover an entire building's electrical system, including outdoor workshops or garages. They do not generate a frequency that radiates out from a point (and therefore are not limited to distance or square meterage). They work equally well over the entire home. EarthCalm home protection products do this by utilizing the electrical principle of resonant frequency modulation. They introduce or modulate information contained within their highly specific circuitry into the standing voltage of a home.
