Closed system, fan looks good, assume it's blowing good, think I'd look at filter. Maybe more is better, in this case.
tlranger Reviewed by tlranger on . Question about carbon filter/fan My closet is 7 feet long by 4 feet wide by 7 1/2 feet high....the cubic feet if im correct is 210, Ive read some sites say you want to exchange air every 2 minutes then some say 5 minutes. So at 2 minutes it would be 105cfm and 5 minutes it would be 42cfm. Which should I am for? My issue is I have a fan/filter combo I bought from my local HTG supply store, the fan (4 inch) is rated at 170cfm and the filter is 150-265 cfm. Only problem is it doesn't seem like its helping with the odor at all, Rating: 5
