Query: Cleans good

I know this thing cleans the air. It only took me 5 hours to figure that out. I bought the thing, hooked it up, and a little later I pulled up the rods and they were dusty. Maybe some people have clean houses without dust but not here. The funny thing is, is that my buddy bought one the same day same time and his collection on dust was nothing. I think it has something to do with our different A/C systems. I have centeral and he has individual. I wonder if Consumer Reports was using centeral A/C in there tests. Who knows. As for 50 parts per billion ozone...I think a fart is more that that. If you smoke, buy it. If your house is dusty, buy it. If you beleive ther is a hole in the ozone and want to do something about it, buy it. If you are a memeber if PETA, don't buy it cause you are crazy.
