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.
