Prozone Air Purifier
Ultraviolet Whole-House Air Purifier



Properly applied, the Whole-House Prozone Twister air purifier generates safe levels of ozone using germicidal ultraviolet rays for superior reduction of odors. For whole-house air purification, it should be placed in front of your heating system's cold air intake vent.


The Prozone uses Ultraviolet-C light to generate the optional ozone. It has NO ozone plates, nor does it use any of that technology that requires frequent maintenance. The UV-C method is the best way of generating ozone, particularly with the patented UV lamp design that the Prozone uses (United States Patent 6,426,053). The 185 nm UV-C wavelength generates pure ozone and no oxides of nitrogen (NOX).


The UV lamps are self-cleaning.
Regardless of the dust in your environment, it is not normally necessary to clean the UV lamp. We do not offer this product for removing dust.

The benefits of proper ozone levels for getting rid of odors, and the characteristics of 254 nm UV-C rays for killing germs, are both well-established scientific facts. Please see the ozone FAQ.

1. The Germicidal, hydroxyl-producing UV lamp is always on. It produces no ozone.

2. The ozone-producing UV lamp is normally off. It can either be controlled by the timer or by the timer override switch so that the unit produces ozone continually* to deodorize a car or motel room. (In this case, the blower should be on so that the ozone penetrates the ducts).


  • Lamps are rated for 20,000 hours of continuous use.
  • 60-Day Money-Back Guarantee and One-Year Warranty.


* Not for occupied areas in the continuous-ozone mode


The Prozone Twister Air Purifier does a superb job of eliminating even very strong odors.

The Prozone Twister

Advanced Oxidation Air Purification System

enjoy the best
outdoor air
imaginable ... indoors!

The Twister™ is more than an air purifier. This unique and powerful device destroys biological & chemical pollutants in the air and eliminates their associated odors — with no harmful by-products. The Twister is the only air purification device for individual use to harness the force-multiplying power of advanced oxidation. With its patented arsenal of nature's secret weapons — advanced oxidation, pure O3 ozone, and germicidal ultraviolet light, it simply cannot be compared to other products that just attract and hold pollutants and pathogens.


Great for Home, Car, Office and More
  • A single unit can treat a 3,000 sq. ft. home or office — place it in front of the air return to help clean up the ductwork.
  • The Twister is great in commercial settings where odor control & sanitary conditions are a particular concern, like health clubs, spa enclosures, locker rooms, pool rooms, veterinary clinics, and medical and dental offices.
  • Hotels and car rental agencies use it to convert smoking rooms or cars to non-smoking units.


Versatile and Customizable
Three operating modes and a precision-engineered timer allow full customization.

  • Ultraviolet Sterilization This light-duty mode is always on and provides general cleaning of the air.
  • Timed Ozone and Advanced Oxidation The timer is set for ozone generation at planned intervals, such as when residents, clients or employees are present.
