Dirty Electricity filters


Fitting a few DE2 filters in your house helps reduce the dirty electricity by lowering high-frequency noise on your house wiring. They plug in (and occupy) a standard 13A mains power socket. Levels of DE are checked if you engage me for a consultation by using a deTekta meter, and usually 2-3 filters are sufficient to treat the entire 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.

Filters have a UK plug configuration – please contact me if you require a European adaptor.

These DE2 filters have a larger capacitor (more effective at reducing DE) and, uniquely, have an internal electric field screen which greatly reduces the electric field around the outside of the filter. They also have an internal safety fuse and other components.

Technical detail: The unit contains a 15 microfarad a.c. mains-voltage rated capacitor, discharging resistor and fuse. Unlike some DE filters on the market these 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.

Please note that if you have solar panels installed it is unlikely that you will be able to completely eliminate dirty electricity with these filters due to the high levels of DE produced by the AC inverter.
