The Stroom Master® is our only product which is designed to filter AC EMF(dirty electricity) pollution generated by voltage transients and harmonics present in power lines. The Stroom Master® is also Equipped with our patented SPIRO® technology, it contains a quantity of SPIRO material that is 3 times stronger than that of the SPIRO CARD. This creates a joint effect that is capable of filtering noise within the electrical wiring line, while naturally polarizing the fields surrounding the electrical wiring and the area where the filter is attached (up to 8 ft radius). The Stroom Master® is a 2-in-1 filter that we recommend you place every 200 sq ft or in each room of your home. Although it does contain SPIRO material, it is mostly designed for dirty electricity so we recommend using a SPIRO DISC as well in order to keep your home completely electrosmog free. This filter has been found to not affect the performance of the devices it is used with; on the contrary, laboratory tests have shown that it is fully compatible with them, optimizes their operation, and lengthens their useful life.

Protection from Dirty Electricity

AC Filter for Harmonics & Transients (Dirty electricity) / Multifrequency Filter Protection of RFR / ESD / LF Magnetic Flux

The STROOM MASTER® is a 2-in-1 solution for protection against dirty electricity and surrounding high-frequency radiation. It has an active filter that cleans the noise of harmonics and transients in the electrical lines; as well as a unique passive filter with the SPIRO® material for all radio frequency interferences entering the wiring. We recommend installing the STROOM MASTER® using an EMI meter to ensure the full reduction of interferences and the most efficient use of filters in a specific space.

How to use it?

  1. Plug it into an outlet or power strip.
  2. Check the blue indicator light on the front to verify that the device is on. You can use the stickers inside the packaging to cover the light indicator and avoid unnecessary light at night.
  3. The STROOM MASTER® has a built-in outlet that allows you to plug in any other device or appliance.
  4. Use an EMI meter (electromagnetic interference meter, sold separately) to check before and after levels of dirty electricity. Recommended levels should be below 150 mV minimum, the ideal being below 100 mV.

For an average household or small office, you should use 1 STROOM MASTER®  every 194 sq ft. For example, a house with a 970 sq ft area should have 5 STROOM MASTER® filters installed.


Ideally, install one STROOM MASTER® in each room (Kitchen, Family Room, Living Room, Home Office, Bedroom, etc.). Make sure you install it where your main EMF sources are located (Wi-Fi router, microwave oven, etc.)
