What is Dirty Electricity?

Dirty electricity is an anomaly caused by high voltage surges traveling along standard wiring that only has a capacity of 50/60-Hertz. Also known as line noise or electrical noise, it is an increasing source of pollution in the environment today. You can read more about Dirty Electricity here

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.

  • Easy Install

    Just plug the filter in to a mains socket and it will get to work reducing the dirty electricity in your home.

  • Upgraded Model

    Our new DE2 filters now have a larger capacitor which makes them much more effective at reducing dirty electricity.

  • Safety First

    Our DE2 units are fully approved to European safety standards.

  • Internal electric field screen

    This greatly reduces the electric field around the outside of the filter.

  • Made in the UK

What is Dirty Electricity?

Dirty electricity (DE), also known as dirty mains, dirty power, or electrical pollution, is a term that describes the problem of electromagnetic noise being on the mains wiring of a house, when it isn’t supposed to be. Basically, your electrical supply is supposed to have just a 50 Hz sine wave on it, but this is rarely the case. There are almost always significant 2nd and 3rd harmonics (100 and 150 Hz in Europe, 120 and 180 Hz in USA), but these are not thought to be any more harmful than the pure sine wave.

Dirty Electricity Effects

Dirty electricity typically interferes with optimum functioning of electronic appliances, creating a phenomenon referred to as power line EMI or electromagnetic interference. Today, as electrical appliances draw power from the main building wiring, it not only gets the standard electricity as initial input but also receives the erratic surges and spikes of energy. Many electric appliances malfunction when this happens as they are not equipped to handle this dirty electricity.

  1. DC

    Meter easy to use, filters worked well. My dreams became much more intense, and the place felt a lot safer with the filters in place

  2. KW

    These are essential in our 1930s semi-detached house. We don’t know how old our wiring is, but the filters in place are assisting, especially after we took measurements using the Magnemeter. We’ve plugged one near to the electrical fuse box, another in the kitchen, one in the main bedroom and one the lounge.

  3. TH

    I live in an affordable housing estate where there are electric wires in the walls & ceiling every 2 metres. Got 2 of these & the buzzing sound has gone from some God awful ‘dirty-hum’ when it’s quiet to a deffinatly more bearable, ‘cleaner’ resonation where these, umm, ‘nerve-interfering’ frequency fluctuations are less destructive!
