O3 LEAF Plug-In Adjustable Ionic Ozone Air Purifier (GREEN)

This really freshens the air. I use it in conjunction with a Ionizer air system. Can’t smell cats in my house any more

Seems to be working really well, freshens a room quickly, I love the fact it can be adjusted.Update: The great thing about this is at the lowest setting, you can keep it on in a room, and it just puts out enough ozone to be at borderline conscious awareness. If you have it on maximum it is very strong. The more towards maximum you have it the more of a "humm" you hear, but its not bothersome to me at all. I'm just happy that it clears the allergens from my environmentI bought another blue one for my mother and she loves it.

It clears a room of smoke, scents, and odors with a reasonable level of fan noise. In the bedroom, it provides "white noise" that sometimes helps with getting to sleep. It is a bit pricey for what it does but it does work for its intended purpose.

I had edenpure heater that I love. I do not see any difference is air qualitye after 3 days using this leaf. I do occasionlay smell bleach. this is not a pleasant smell. would not buy again.
