Reduce dirty electricity in your home by fitting some Dirty Electricity Filters. They plug into (and occupy) a standard mains power socket and will help to lower high-frequency noise on your house wiring. They filter out high-frequency harmonics from the electrical environment reducing the possibility of leakage into your home. It has a light to indicate it is operational and the filter also doubles up as an electrical outlet.
You can determine the number of filters you need through EMF testing (dirty electricity EMI meters are also available to buy or hire). This pack of 15 is most likely needed in a large home with a solar inverter. You can place them wherever you have a socket and preferably close to the source of dirty electricity for optimal use. It is always best to measure your dirty electricity before deciding how many you need and where you should place the filters.
