It is very important to learn the truth about ozone air purifiers before you consider a purchase.
Lets start at the beginning before we discuss ozone air purifiers and what to watch out for. Ozone is a normal trace element that exists in the Earth's atmosphere. Activated oxygen, another name for ozone, is a three-atom form of pure oxygen (which has two atoms). When ozone comes into contact with pollutants it loses one of its atoms and "oxidizes" the pollutant, thereby destroying it.
Ozone air purifiers use electricity to produce ozone and then release into into the air to "seek and destroy" pollutants. Sounds great, but there are some important drawbacks to consider.
First, ozone in very high doses can causes irritation to the eyes, nose and throat. Now, most ozone air purifiers are not capable of producing those levels of ozone, but it is something to keep in mind.
Second, ozone air purifiers tend to cause an unpleasant "sweet" odor or smell in the room being cleaned. Some people find this smell objectionable and some people love the smell. It is similar to the smell after a thunder storm.
Lastly, ozone air purifiers have no affect on solid particles like dust. Ozone by itself is simply not effective at removing these types of particles.
Of course, along with these negatives comes some strengths as well. Ozone air purifiers are highly effective against odors. Ozone also is capable of destroying chemicals and bacteria.
Where to Use Ozone Air Purifiers
After taking into all of the above, it is obvious that ozone air purifiers are particularly well-suited for salons, bars, and other areas with high levels of pollution and strong odor.
Ozone air purifiers can also be used in homes as long as the air cleaner utilizes more than ozone technology (i.e. in combination with a HEPA filter and a carbon filter). You would also want to make sure that the ozone generator could be turned off or reduced so that ozone levels could be kept at a minimum.

The 6 stage and the 10 stage Nutri-Tech air purifiers not only have a timer for the ozone generator but now also have a 'High / Low' switch for people who want to keep the ozone on all the time.
