VIVOSUN 4 Inch Air Carbon Filter Smelliness Control with Australia Virgin Charcoal for Inline Fan, Grow Tent Smelliness Scrubber, Pre-Filter Included, Reversible Flange 4" x 12", Black

These carbon filters are great for keeping the smell contained. Second 1 so far. Lasted 1 year with multiple grows.

Love this air filter have purchased it a couple times, last longer than other brands I’ve tried and definitely great quality and value for your buck, fairly large noise level is loud but as what should be expected, great for removing dust, smoke, and odors

i got this so my neighbors wouldnt have to deal with the intense odor that can come from growing and it works great!!!!! like i was shook that i could only smell my grow when the tent was open!!!!!

Perfect Filter
