It's a canister filled with carbon filters.Odor is a particle.It can be caught in a manner than it would be displaced or removed odorless! Much like what charcol does for moisture.It removes it from the grow room and traps it.I'll tell ya a simple way to remove moisture.Build a small can out of sheet metal or use a five gallon bucket.Fill it with KINGSFORD charcol,to the top! Cut a 4 inch hole in the bottom before ya fill it.Cut the same in the top.Attach 4 inch dryer flex to it on both end put a fan drawing not blowing,and vent to underneath the house.Change the charcol twice a month.Moisture will make charcol mold and mildew.No worrys bout mold if ya change it.
