VIVOSUN 4 Inch Air Carbon Filter Odor Control with Australia Virgin Charcoal for Inline Fan, Grow Tent Odor Scrubber, Pre-Filter Included, Reversible Flange 4" x 14", Black

Solid filter that does exactly what it claims – noticeable reduction in odours within a couple of hours. Build quality feels strong and it comes with the hanging straps which makes installation much easier. It is on the heavier side, so make sure it’s properly secured. I knocked one star off because the included pre-filter could be a bit tighter fitting, but overall very effective.

Great Product, Fast Shipping! I’m very satisfied with this purchase. The item arrived quickly and was exactly as described. The packaging was secure, and the quality of the exceeded my expectations. I would definitely buy from this seller again. Highly recommended!

Absolutely fantastic I can’t say the fan I replaced cost nearly double it’s got nothing on this fan outstanding quality i can’t say anything else great job

Makes a notacable difference

arrived with no hangers and had to open it when i didnt want to use it yet to check for them because vivosun asked me to even though i had checked inside with the outer bag on. Not too happy at the moment

Vivosun filter. Very good filter seems legit and im happy with the product. Beware not discrete pictures and branding on outside of package.

Todo lo que he comprado ha venido en perfecto estado.

Ottimo

effective in reduction or mitigation, at least, of 'stink-sauce' type odors. I did use the brand for and in a grow-op sitiation. It worked fine. "the smell, of stink", no such thing with this filter and a fan. Stink has nowhere to hide, and it gets trapped in the pores in supposition so running is no help, either. Good for about a year with my intermittent use. If it doesn't seem to work for one, It may be a matter of skink - there maybe too much even for this to handle is the guess. It can I surmise, fix gf related problems, but, only in the immediate vicinity/or environment. Cheers!

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!
