  • Superior quality, long-lasting, highly effective, reliable, genuine negative room ionizers. Generates an optimum level of high-density negative ions.

  • Very effectively removes particles from the air as small as .01 microns, such as pollen, dust, mold spores, pet dander, and other allergens.

  • Negative ion output 80 to 100 trillion ions per second, externally. (That is, out into your room, instead of being captured and trapped inside the ionizer).

  • For large or small rooms - covers 4000 cubic feet
    (a 20' W x 20' L x 10' H room).

  • Ionization method requires no filter, so there's never a need to buy or clean filters.

  • Neither are noisy fans or blowers required. Room air is cleaned and purified noiselessly- completely silent.

  • More effective than expensive HEPA filters or electronic air cleaners: ionized room air does not have to be circulated by a fan and pass through a filter to be cleaned.

  • Uses no chemicals, perfumes, filters, or agents.

  • Does not produce harmful EMF (electromagnetic fields).

These ionizers produce an optimum level of negative ions in your room.

We've seen other ionizers that we couldn't even measure the negative ion output from (though we could walk outside and measure the natural level of negative ions outdoors with the same ion detector). Another widely advertised ionizer produced such an extreme level of negative ions that it actually caused a computer in the same room to malfunction.


Our ionizers are Designed to Last for years.

We still have the first ionizers we ever built. And they still put out the same level of negative ions as they did when they were new.


Running 24/7, average electricity cost is only about 4 cents a month.


The part that wears out quickly on other negative ion generators.

The one part that wears down on ALL negative ion generators (the ion emitter) is not only replaceable, but long lasting.

Standard SSE long-life, plug-in negative ion emitters are reliable, replaceable, inexpensive, and user-renewable.

Our optional* long-life CFE ion emitters are made from a high-tech, space-age material that is virtually maintenance-free. The CFE emitter requires no trimming, since the diameter of the fibers is almost microscopically small (only 0.8 microns). And dusting off the emitter is only needed 2 or 3 times a year.

The CFE simply plugs into ionizer in place of the standard SSE emitter as shown below.
