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, and now that my plants are far into flowering the smell is really potent. What am I missing here? I have the air being pulled in through the filter and its mounted high near my ceiling about midway on the side in my closet. I just dont get why it doesn't seem to be working, I started to buy a new fan/filter but after doing all the calculating it appears that my fan/filter combo should be enough. Do I need a fan speed controller? Is the air being pulled through to fast or? Im lost right now and need to fix this asap as I haven't been able to have company over because my house smells like a family of skunks have died in it heh....Thanks!!!
