Dirty Electricity reduces 95% with whole home filters

Updated: Jun 9

We recently installed whole home dirty electricity filters on our home electrical system and the results are incredible! Our Dirty Electricity has reduced over 95%!


It is our view that every home and business in Australia should have whole home DE filters installed as standard to protect us all from EMF's.


So what is dirty electricity?


Dirty electricity (DE) is a deviation from the standard 50 Hz electrical wave in wiring, which causes spikes of electrical current in electrical wiring and devices. DE is also called Electro Magnetic Interference (EMI) and is commonly measured in volts (V) or millivolts Peak-to-Peak (mVp-p) using an Oscilloscope or Power Line Meter. The Power Line EMI Meter will measure DE. Common sources of DE include:

  • Solar panel inverters

  • Variable-speed motors, like inverter air conditioners

  • Electric vehicle charging

  • Neighbour high DE devices like solar panel inverters

  • Dimmer lights

  • LED lighting

  • Compact fluorescent blubs


Exposure to high levels of DE has been linked to potential health effects such as the increased risk of cancer, neurological effects, cardiovascular effects, reproductive effects and impact on sleep. We believe that exposure to high levels of DE in our previous home significantly contributed to us developing Electrical Hypersensitivity (EHS).


This is what our DE looked like on an oscilloscope, with our air conditioning on:

Dirty Electricity waveforms shows as large blue waveforms on Oscilliscope with airconditioning or solar inverters on and no filters
Dirty Electricity waveforms with airconditioning on (solar panel inversion causes similar waveforms)

The blue waveforms show the high frequency transients above the standard 50Hz and should be a flat blue line. These transients radiate out of the wiring of your home and out of your appliances affecting your body which is also a complex electrical system. These transients are caused by our air conditioning units when active, however, the same transients appear when solar panels are inverting DC to AC power, which usually happens continuously in daylight hours. We have not installed solar yet for this reason.


We needed a solution to reduce our exposure to DE and we have finally found it....whole home dirty electricity filters! Previously not available in Australia, whole home filters are now here and we believe every home and business in Australia should have these installed.


Marco Simeoni from Spectral Design is the designer, manufacturer, supplier and installer of whole home dirty electricity filters here in Australia. Marco is a qualified electrician but more importantly Marco is also a qualified EMF Technician who specialises in low frequency EMF's from electric, magnetic and dirty electricity sources.

Marco recently installed dirty electricity filters on our home electrical system and the results are incredible. This is what our DE now looks like, with our air conditioning on, after the filters were installed, a reduction of over 95%:

A 95% reduction is a really great outcome, substantially reducing our exposure to EMF's from DE. As we are electrically hypersensitive we want the levels to be even lower so Marco will be further refining the filtering, possibly adding one more filter and completing a minor rework of our electrical mains board to get the levels reduced by >99%. The same reduction in dirty electricity from solar panels can be achieved by installing these filters.


So what does a whole home dirty electricity filter look like and what does it do. Well in simple terms the filter (shown in the black box below) captures the DE coming in from external sources and the DE generated internally by solar, air-conditioning inverters and other appliances. It then smooths the current releasing it back into the electrical system without the DE spikes. If it was not filtered the high DE would radiate out of the wiring of our home and out of our appliances and we can feel it.

And when it's all installed Marco checks the EMF levels to ensure the desired low DE and low EMF outcome was achieved,

Compared to many other DE filters, these whole home filters by Spectral Design don't create magnetic fields internally and they block the DE from entering the home wiring from the street.


Fill out this DE filter enquiry form and Marco and his team will tell you more about their DE filters, provide a quote and book you in to get them installed in your home or business. Marco personally installs these filters along the entire east coast of Australia (TAS, VIC, NSW, QLD) and also in South Australia (SA). If you are outside of these areas Marco can supply the filters and guide a local electrician to install them for you.


Safer EMF are also qualified EMF technicians. We can measure DE and all other EMF's and convert your home and business from wireless to wired. See our range of Services available online Australia-wide and onsite from Brisbane to Northern Rivers NSW.


You can also hire or buy EMF meters including DE meters from our Online shop and DIY
