Fitting a few DE2 “Dirty Electricity Filters” in your house helps reduce the DE by lowering high-frequency noise on your house wiring. They plug in (and occupy) a standard 13A mains power socket. We suggest a maximum of one-per-room or if you are starting out, two for the whole house. Please note that they reduce problematic high-frequency noise between the 230 volts phase and the neutral and don’t lower the normal electric fields created by house wiring.
Technical detail: The unit contains a 10 microfarad a.c. mains-voltage rated capacitor, discharging resistor and fuse. Unlike some DE filters on the market ours contain an electric-field screen inside the case which is connected to the Earth pin. Some filters on the market are not even internally fused. Our DE2 units are fully approved to European safety standards.
