The Prozone PZ-6 destroys pollutants and pathogens, both chemical and biological, without giving off ANY harmful byproducts. It will eliminate odors, leaving your bedroom or your office smelling fresh and feeling fresh. It is compact, only 6” wide, 6” high and a mere 1.5” deep and weighs less than 2 pounds! It is virtually silent with low-cost operation (less than a 50 watt light bulb). There are no filters to change or plates to be cleaned — just wipe the dust from the fan vent as needed. It emits 100% pure ozone with no nitrogen byproducts.
