A little is good you dont want it coming out to fast or it will not have time to let the carbon retain and trap the smell.

wet your hand and place it like a few mm from the filter. wetting your hand raises your sensitivity to air moving around it and you can tell if air is moving near it or not.

If you smoke cigarettes you can put a burning one in front of it and watch the smoke (what I do) you could use a joint if you don't or you can light a match and watch it move the flame, or use a lighter, or a candle

it all works great for "seeing" air move

ya i guess it could have i just made it though so i dunno if it would do it that fast i have the grow in the closet still but there are a few light leaks it doesnt matter for the plants as they are snowryder autoflower strain but ppl do come in there and i thought i might could control smell and light better in a small fridge but looks like ill just have to stay with the closet any suggestions for carbon filter set up in a closet? also gets way too hot in the fridge
