Yea I have a hole cut out in my closet and its venting into the next room, I took the duct off to feel it and its blowing hard. I was a noob when first starting and ran my fan 24/7 from the start of vegeing though it did help with heat. Its been running constantly for almost 5-6 months now, thought they had a longer lifespan but was wondering if I should try replacing the filter. Might get a bigger one and try that is compatible with the fan I have see what happens. Still curious as to how growhand recommended setting it up so I could give that a try, thanks yall.
GrandRefa Reviewed by GrandRefa 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
