Fans and odor control

I am opperating in a large closet.8' by 4'. I have looked at charcol filters and have found some nice ones for about 200. Anyone have suggestions on what i should get? Peace

are you asking for which brand or how many cfm cubic feet per minute filter you should get ?

I'm going to be growing in a closet to and while im a bit of a noob what I have found is that the cfm should be equal to your rooms cubic size/5 according to htg. This replaces all of the air in the room every 5 minutes. I'm planning on going with 2 of the cheap fabreeze carbon filters they sell at walmart for lk $20 i think. I've also been told that you can never have to many carbon filters so if you have the cash and room for a large carbon filter I would definetly get it. rather be safe and go over the top than sorry and save a few bucks

i would go with one filter but a good filter so you have a 8*4 room and let's say 7 feet high that's 224 cubic feet. 224/5=44.8.i personally would not buy a filter from walmart but how many cfm are there rated for? i could not find 50 cfm filter so i would go with a 98cfm can filiter the smallest i see people selling

but you can go to your local hydroponics store which i would recommended
and then for inside where your growing get a ONA puck or spray for 20 bucks and will prevent any bad smell escaping when opening the door as a last line of odor defense

Also are the fabreeze filters charcoal?

yea, i have not actually seen them yet but have heard people talking about them around riu wuite often now. They seem to work pretty good from what people are saying

i333t, it is about 7 feet high and about 224 cf. I know you have a suggested filter but should i go with somethin that says its good up to 200-300 cfm? or is every 5min still good rather than cfm?
