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

Had a time hooking it up because there was not much room to move around. Got it finished and closed up the tent. The smell was gone when I got up the next morning. I am going to look at the cost of a refillable one next

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!

Just as it should be

Tal cual como se describe

It’ll scrub the air for 6 to 8 months and then you can use it as your intake filter for eternity!

Works as it should.

Works very well for a good price. Will buy another when I need one. Like that it has hanging loops.

Works as designed.
