"I would classify it as a medium duty scrubber. It eliminated the odor from my room, but it was not very smelly to begin with. I am growing mostly Grapefruit Haze, and it has more of a fruity aroma. I have one Sour Diesel plant that I know will be stinky, soon. I say medium duty because after eliminating the marijuana odor, I decided to really test it out. I had a friend spray some body spray in the air inside the grow room. I was in the next room, where the grow room vents to. I could smell the body spray, but just lightly."

Got rid of the SD, only have Grpfrt Hz and G13. No smell.
