Hi all... I have a carbon filter that's been sitting in a box for 4 or so years unused that I got 2 good grows out of. It's a phresh. My box is finally done and I thought to test the filter I'd throw a stick of incense in there to see if I noticed any smells coming out of the exhaust. I did clearly smell it. 1) Is this unrealistic test? Will a carbon filter be able to filter out the smell of incense? I would think it would. 2) Could just being in a box for 4 years, it wasn't sealed in a plastic bag at all but was in a sealed box, render the filter useless? I will check for leaks but I'd be surprised if there were any. I taped it up pretty well. Your thoughts, as always, are very much appreciated. Thanks!
