Invincible, my unit does refresh my apartment. When I used to come home from work, the first thing I had to do was open the windows because the air didn't smell too good. Now , the air does smell a lot better. I can also smell the ozone when I walk in. It doesn't have a fan but you still get air currents in the room. I am thinking of getting a small girating fan. I keep my ionizer about 4 feet high. Also, I sleep better at night and even more so after I started to take hydrogen peroxyde before going to bed. I think, as Moreless was saying, I was too acidic and the extra oxygen from the ionizer and the HP is making a difference. I gargle with three parts water and one part3% HP for when I get a cough or sore throat and that helps.
