Dirty Electricity
Harmonics and transients riding on your wiring create electromagnetic pollution that lives inside the conductors. SPIRO products in the room can't fully reach it. The Stroom Master was built to solve this specific problem.
What dirty electricity is and why it matters
Every electronic device in your home generates harmonics and transients that feed back into the electrical wiring. Switch-mode power supplies in chargers and laptops, LED drivers, dimmer switches, solar inverters, wireless chargers — they all inject high-frequency noise onto the 50/60 Hz power line. This noise is called dirty electricity.
Your building's wiring then acts as an antenna, radiating that noise into the surrounding space. The result is electromagnetic pollution you can't address by placing a SPIRO Disc in the room, because the source is inside the conductors themselves — conducted interference, not radiated interference.
Dirty electricity affects both biology and technology. It disrupts sleep quality, increases oxidative stress, alters nervous and hormonal function, and shortens the lifespan of appliances plugged into the same grid. In homes with dense smart home setups, solar panels, or EV chargers, the problem is significantly worse.
Dirty electricity in bedroom wiring interferes with autonomic rebalancing during sleep.
High-frequency noise on the grid increases free radical production in the body.
Harmonics cause material fatigue and shorten electronic component lifespan.
RF noise on the wiring competes with and degrades WiFi signal propagation.
Hormonal and neurological disruption from chronic low-level grid interference.
For people with electromagnetic sensitivity, dirty electricity often triggers the worst symptoms.
The problem with conventional dirty electricity filters
Other dirty electricity filters on the market do reduce harmonics on the line. But they generate their own low-frequency electromagnetic emissions in the process. For most people, this tradeoff goes unnoticed. For people with electromagnetic hypersensitivity (EHS), it makes things worse. NOXTAK spent years working with electrosensitive individuals who experienced discomfort when using conventional filters before developing the Stroom Master.
Stroom Master vs. conventional filters
Conventional filters
Reduce harmonics on the line but generate their own low-frequency emissions during operation.
Not suitable for electrosensitive individuals. Can worsen EHS symptoms.
No SPIRO material. No filtering of the filter's own emissions.
Addresses conducted interference but adds radiated interference.
Stroom Master®
Active electronic low-pass filter that reduces harmonics and transients on the line.
9 SPIRO films built into the device filter the emissions the filter itself generates during operation.
Designed specifically for electrosensitive people. No secondary disturbance component.
SPIRO filtering power of 3 extends beyond the grid into the surrounding space, also reducing microwave interference (4G, 5G, WiFi, Bluetooth).
UL-certified for safety. 3-year warranty on electronics. SPIRO films work indefinitely.
What happens when you clean up the grid
The Stroom Master filters dirty electricity from the wiring. But once you clean up the electrical grid, secondary effects become noticeable throughout the building.
WiFi improvement
Stroom Master units deployed in series improve WiFi propagation throughout the building. Spaces with poor or no signal gain reliable connection. RF noise on the grid competes with the router broadcast. Remove the noise, and the signal reaches further.
Appliance protection
Dirty electricity causes material fatigue in electronic components. Filtering it extends the operational life of everything plugged into the grid — from kitchen appliances to HVAC systems to entertainment electronics.
Better SPIRO performance
In environments with severe dirty electricity, the Stroom Master clears conducted interference that SPIRO Discs cannot reach. The combination of Stroom Master (conducted) and Disc (radiated) covers both vectors of electromagnetic pollution.
Cybersecurity & Data Protection
Dirty electricity creates inadvertent channels for data leakage. Filtering harmonics and transients from the grid helps protect signal integrity and reduces electromagnetic vulnerabilities.
How many Stroom Master units you need
The number depends on your building size, the number of appliances, and the density of smart home equipment.
Placement tips: Connect to main sources of electrical use, not every outlet. Same electrical line as the appliance is sufficient — the filter doesn't need to be between the outlet and the device. Start with the bedroom (sleep quality) and the kitchen (highest appliance density). Add units in rooms where WiFi coverage is weakest.
How to verify it's working
Use an EMI meter (such as the BEEM Meter) to measure millivolt values on the wiring before and after installing the Stroom Master. You'll see and hear a significant reduction in line noise. The target is below 100 mV. If noise remains above 150 mV, add a second unit to the same outlet or a nearby one.
For the SPIRO films' effect on the surrounding environment, a high-frequency spectral analyzer or WiFi signal performance tool (like NETSPOT) will show measurable improvement in signal quality and reduced RF interference in the space.
