Greenwave Broadband EMI Meter
You can use this super easy meter to measure the dirty electricity or EMI found on the wiring in your building. Like all forms of non-native EMF dirty electricity will also adversely affect your health and well being.
The meter gives you a before and after percentage reductions in dirty electricity when you start adding filters. The meter can be used in conjunction with any of the dirty electricity filters on my website. Ideally you would measure with filters so you can work out the optimal number and location of filters around your home.
