Hi, my room smells all the time, I have a fan that pulls air from the house into the room and out the window. The exhaust is pretty strong, my house doesnt smell but when I go into the flower room it smells pretty bad. How can I get rid of the smell? I was thinking of adding another fan and filter to cycle inside the room but that isnt really an option right now. Besides, even if I add another carbon scrubber inside the room, that air would be drawn out pretty quick. Any ideas?
