Dirty Power Protection


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.

What is it for?

It’s an EMI AC (electricity) filter (eliminates the noise in the electric line, harmonics and transients at frequencies greater than 60 Hz) that contains a special formulation of SPIRO to cover the DPA (Data Package Alterations) emissions from radiofrequency. It contains a Spiro power 3 times higher than the SPIRO CARD. It has a joint effect that is capable of filtering the noise within the electrical wiring and, at the same time, naturally polarizing the fields surrounding them, especially radio frequencies and microwave radiation.

How to use the SPIRO Stroom Master?

  1. Plug into an electrical outlet or power strip.
  2. Check the blue indicator light on the front to verify that the device is on.
  3. Stroom Master has a built-in electrical outlet that allows you to plug in any other device or appliance.

Use an EMI meter (electromagnetic interference meter, sold separately) to check before and after dirty electricity levels. Recommended levels must be under at least below 150 mW.

Where to place it?

Ideally, we suggest using dirty power filters every 200 square feet (18 square meters). For example, in a house of 1000 square feet (90 square meters), an average of 4 filters is enough, however, that’s a house’s average size. Could be more or less depending on each case.

Electrical appliances and electronic devices add electro pollution to the grid, and the main sources of pollution are usually close to these major appliances and devices inside your home. Our recommendation is that you plug those appliances using our dirty power filter in order to ensure that more interference is not being added to the grid.

Outdoor EMF exposure could raise the interference in your electrical system; so, If your home is located near a mobile phone base, has a smart meter, or an electrical panel is in one of the bedrooms, the use of a SPIRO DISC is recommended to complement the solution and create an electropollution-free environment.

What makes SPIRO Stroom Master different?

The SPIRO Stroom Master is superior to any other dirty power filter because:

  1. Protect the users from the magnetic field produced by the filter itself, emitting and clean EMF that is fully compatible with the human body’s bioelectrical system. All other dirty electricity filters in the market produce a secondary effect because of the polluting EMF they produce, which can cause significant discomfort in electrohypersensitive people.
  2. It covers a broader frequency spectrum. Due to its integrated passive properties, It reaches 300 GHz, while other filters hardly reach 100 KHz, or 1 MHz in the best of cases. 
  3. You can verify its functioning with a common EMI LINE METER.
  4. It has a UL Quality compliance certification, which demonstrates its professional standard and unique quality.

The STROOM MASTER also protects your health. It’s based on NOXTAK’s patented and scientifically proven technology, that organizes the radiation spins (Spin Radiation Organizer – SPIRO). It contains 9 nanotechnology manufactured films that have proven to effectively filter dirty electricity inside the power lines while guaranteeing an EMF-free environment.

The SPIRO Stroom Master, is unique in its functionality, because it does NOT BLOCK the emissions, but it filters them and eliminates the disturbances and interferences within the power lines, neutralizing the harmful effects of EMF and making it compatible with our body’s bioelectrical system. It’s fully recommended for electrohypersensitive people, as it’s the only dirty electricity filter that does not emit any EMF while functioning.

More benefits
  • No static
  • Better connectivity
  • Less heating
  • Increased energy efficiency and saving
  • Increased durability of devices

Life-span and functioning

UL Certified for 3 years as an electronic filter, the Spiro films inside (9) It doesn’t require batteries. The technology inside the filter (the films) exhibits a permanent and stable magnetic dominance behavior; and these properties are perfectly kept as long as the device is well-preserved.
