Review on 🌬️ 6"x24" TerraBloom Carbon Filter with 46mm Thick Charcoal Bed - Enhanced Air Filtration for Grow Tents, Homes, and Commercial Applications. Eliminates Odors, VOCs, and Chemical Smells with Up to 550 CFM Airflow. by Lucia Ingalls

This stuff can make the stinkiest of plants almost disappear. I had 90 degrees. The bend after the filter and about 2.5 feet between it and the onboard fan and doing it at medium speed with a 395fpm fan killed 85% of the stink. There will still be a very slight smell in the room, however the smell will never spread outside of this room. I reckon that now that I've adjusted it properly, 95% of the odor is eliminated. I don't think 100% can ever be eliminated, but you can still have company and no one will know of your growth. So it's very efficient.
