i use activated carbon filters made by rhino. They work 100% .. not so much as a slight smell, infact, you cant smell anything.ona mist.
makes it smell like you just did laundry..
all the time..
Isn't it more ideal to pull the air thru a Can filter then exhausting it? Or does it really not matter which way you do it??my grow room is completly sealed except for the door to the room i drilled a six inch hole in the door and ran my exhaust thru the hole and put a can filter on it and could not smell anything outside the room after that and im growing a very smelly strain. the exhaust fans suck air in under the door and it all exits thru the can filter out the hole in the door.
yes always better to pull through a carbon filter rather than to push the air through it. reason being the dust will clog the carbon, hence why they come with a fabric pre filter on the outside.Isn't it more ideal to pull the air thru a Can filter then exhausting it?
