Sorry, didn't mean to flame. I can only state what works in my environment. Ishould have mentioned that the fan is on a rheostat and though running 24/7 it's at about 1/2 speed which should add to the life of fan and filter.

The reason I say carbon is the ony way to go is because I've not needed to worry about smell for years with only an annual vacuum of the outside of filter.

Not To Worry: priceless
grey1223 Reviewed by grey1223 on . effects of ozone hey all, i tried to search the site but couldn't really find much info. in a fit of unsatisfaction with my local hydroponics store and their outrageous prices, i started my own hydroponics supply a while ago. anyways, my supplier doesnt have much to choose from in the odor control department. Theyve got Ona products and blue air ozonators and airballs. Ona leaves this weird funky smell. I guess they work by replacing questionable odors with their own funk. does anyone here use ozone? ive Rating: 5
