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 Kimberly Thomas

Before buying this filter I had a comparable Vivosun 6 inch. Even at maximum fan speed, my grow tent would bulge out from the overpressure. Remember this filter was new. I was a little worried that the positive print would be worse with this new filter since it's longer than my previous one, but my concerns went away when I set the fan speed to its lowest setting and saw that I got the perfect average between negative could reach and overpressure. ! Oh yes, and I feel nothing! best filter on amazon
