exactly as the title states
im making a stealth grow box in a dusty garage so i wanted an intake attached to a filter aswell as an exhaust attached to a filter
my room is 22.75 cubic feet, therefore i wanted to have a 10-12 CFM exhaust with a 5-8 CFM intake fan
1) can i attach a carbon filter with a much higher rating than the cfm on my fans (the smallest carbon filter i saw was 150 cfm) ( yes you can! you want a filter with a higher cfm than your fan, this will allow the filter to work more efficiently and increase the useful life of it)
2) if i attach three 10 cfm exhausts and used three 5 cfm intake fans, would the fresh air in my room still cycle every 3 minutes or faster?
3) where can i purchase fans that can go that low in cfm's? (frozencpu.com, i'll use computer fans)
