I'm looking to get a Can 66 carbon filter, but I was just curious if they work as well as they say they do? They claim more than 99% odor removal.
Assuming the filter is the correct size for your room and fan, then Yes they are extremely affective. Its important to remember that carbon filters become less affective at humidities above 70%.
do you need to buy a fan or anything ? and could i go with a cheap CF for around 10 bucks because i am only growing 1 plant in a closet ?
