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

high quality air filter

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

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

I have bought cheaper and regretted it, this isn't the best, but for a four inch filter it is really good, and lasts. This is a quality brand, also always better to buy most current models.

Working great Nursery side and adult side are most producing jalapeno banana ghost peppers for meat rubs and sauces also growing bell peppers red green and yellow I have four Tommy Toe tomatoes two beefcake and we have four of the great friend cherry tomatoes there are all producing way faster than all my outdoor plants are this and Aerozeh and Vivosun have been a great addition to my garden and growingSincerelyJohn T HarrisonTommy

The Wife loves my new hobby but she hated the smell. I’m growing one indoor plant in a 3 x 2 1/2 x 5 1/2‘ and it stinky install this carbon filter and in my particular case it knocked out 95% if not 100% of the smell, it’s insane. The chain was drastic and immediate, I have it pulling a 4 inch 195 CFM in my fan which is small but for this particular set up as gold

I use these in my grow tent to keep my whole house from smelling like marajuana. Gotta keep that smelll at bay, because my mom hates the smell lol

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!!!!!
