Use a highly accurate micro-surge meter (comes with an AU/NZ plug) to work out how much dirty electricity is in your home. Best used in conjunction with the corresponding plug-in dirty electricity filters to filter out the dirty electricity circulating within your home from internal and external sources. Dirty electricity is generated when the wiring within your home has frequencies other than the normal 50 Hz electrical current. Time and time again I find it is often this EMF that affects those with electrohypersensitivity (EHS) the most. These unwanted frequencies (often referred to as dirty power) piggyback on the electrical wiring in your home resulting in adverse health effects. Solar inverters are notorious for emitting dirty electricity as are CFLs, LEDs, dimmer switches, smart meters, and most computer, electronic, entertainment and kitchen appliances.
