VIVOSUN4 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

Exactly like i expected from the brand, well made and solid construction. There was a large amount of carbon dust all over the housing and package, but that was easy to clean up. Expected it to come with straps, but instead it had small clips on metal wires which left it hanging too low so i swapped out for zip ties. Once added to a T4 fan it was rather large for a 2x2 tent, but moved to my 4x2 tent and it was a much better fit. For the 2x2 i went with the MelonFarm fan/filter intgegrated combo which was the same size as just this filter but had the fan built in which was a huge plus. Overall im happy with the product, though it wasn't the cheapest option. As far as flow and sound, there is not much to say about just the filter, but once hooked up to the T4 fan it was nice and quiet and pulled a good amount of air!

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

Filters the air really nice, removes all the smells in the air. Very happy

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.

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
