well, kind of, it Ionizes the Particles that are in the Air, most of them dissolve into samller particles, but the ones that aren't, when discharged, and fall to the floor, or stick to the wall. The Ozone created (which to my understanding) is a (positive) side effect of Ionizing, or Neutralizing the air. which is what sterilizes, and pruifies the air as well. Which is I guess why Ozone is called a "Natural Bleach"!!
I've read some interesting studies of side effects that these things can cause, when used in the wrong enviornment, such as poorly ventilated houses, where the Air, and house is actually too Clean, and people are easily affected by allergens. How true this is?? I'm not sure, but the company that makes mine says to not run it all the time because of this. One cool thing about it is that it will remove odors, because Ionization penetrates most materials, and can get odors out of things like Beds and Couches, hell it worked on my stinky A$$!!
