Dirty electricity: the EMF source nobody tests for
Dimmer switches, LED drivers, solar inverters, modern electronics: they all pollute the wiring in your home with high-frequency transients. Almost no inspector measures it.
Every LED bulb you screwed in last year is pumping high-frequency noise into your home's wiring. Every dimmer switch, solar inverter, and phone charger does the same thing. Almost no inspector measures it, which is why it's a favorite finding on an EMF assessment.
What dirty electricity is
The power grid sends 60 Hz alternating current to your home, clean and steady. Modern electronics convert that to the DC they need using switching power supplies, which slice the waveform thousands of times per second. The slicing produces high-frequency transients (typically 4 kHz to 150 kHz) that ride on top of the clean 60 Hz and propagate through the whole panel.
Once present on one circuit, dirty electricity spreads. A dimmer switch in the living room affects the reading at the bedside outlet in the primary bedroom. A solar inverter in the garage affects every circuit in the house.
Why nobody measures it
Two reasons. First, the equipment is specialized. A typical mold inspector doesn't own a meter. Even a typical EMF inspector often focuses on RF and skips dirty electricity because the measurement procedure is different. Second, the industry narrative around EMF has centered on wireless radiation (cell phones, Wi-Fi, 5G) for the last decade. Wired transients got left behind.
In my practice, dirty electricity readings account for a meaningful portion of the EMF exposure I find in sleeping areas. A bedroom can read low on RF and low on magnetic field, yet have over 1,000 GS units of dirty electricity at the bedside outlet. Under the Havas lab threshold, 25 mV is considered fine, 50 is elevated, 100+ calls for intervention. I see high levels regularly in homes with modern LED lighting.

What the peer-reviewed evidence says
Magda Havas at Trent University has published a line of studies since 2006 associating dirty electricity exposure with sleep disruption, blood sugar variability in type-2 diabetics, and heart-rate variability changes. A 2015 replication in a Canadian school found measurable cognitive improvement when dirty electricity was filtered.
The mechanisms are still debated. The clinical pattern is consistent. My position: when the cost of measurement and filtration is relatively low, running the test is worth it even if the evidence base is incomplete.
St. Augustine client with seven-year unresolved migraine history. Primary bedroom read 1,200 units of dirty electricity. Solar panel inverter was relocated, two GS filters were installed in strategic places in the bedroom, and the adjacent outlets dropped the reading to 28 GS units. Migraine frequency halved within three weeks.
How to fix it
- Swap LED bulbs for quality drivers. Not all LED bulbs are equal. The cheap ones put 200,500 mV on the line. Quality drivers (EcoSmart UltraViolet, Finally Light Bulb, some Philips LED lines) stay under 30.
- Replace dimmer switches with plain on/off. Dimmers are the single biggest source of dirty electricity in most homes, by a wide margin. A $4 switch swap makes a measurable difference.
- Unplug phone chargers when not in use. Each charger is a small switching power supply. Ten chargers across a house add up.
Tip: Installing Dirty Electricity filters can help in some cases, but anything introduced on the electrical line needs to be used carefully so it doesn't cause problems elsewhere. Some people are also sensitive to the filters and will need to have wiring errors fixed by a licensed electrician.

Every HHZ EMF Inspection measures dirty electricity in every bedroom. The reading is specific. The fix is too.
Why this matters more since 2020
Three changes have made dirty electricity worse in the average American home over the last five years. LED bulb adoption crossed 50 percent of households in 2021. Residential solar installations more than doubled between 2020 and 2024. Smart appliances (inverter-driven HVAC, variable-speed washing machines, induction ranges) became mainstream.
Each of those technologies is efficient and valuable. Each of them also generates dirty electricity. The baseline exposure in a home constructed or renovated since 2020 is measurably higher than in a home from 2010. That's worth knowing before you wonder why you're not sleeping or having chronic headaches.
