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"

High quality and an absolute bargain at this price. Used this as an exhaust filter for my spray booth and it is highly effective! Highly recommended.

Working well, using with a fan outside the tent to pull air out of a double chambered tent. Smell in the room is practically zero while inside the tent stinks 😷

Arrived with massive dent on side and all carbon residue was all over bag. Not sure if checked before shipping or damaged in transit.

Sehr gute Qualität zu fairem Preis! Zum installieren im Growzelt alles dabei mit Vorfilterfilz

Works as described, you can flip this one to give a bit extra time. Easy, good value, I keep one running permanently. Possibly Replace every 1.5 grow? But that's just my results.

Dit filter geplaatst als vervanging van een canfilter dat na ca 1 jaar geen geur meer opnam. De geur was daarna inderdaad onmiddelijk verdwenen. Echter na ca. 2 dagen was de geur weer steeds duidelijker waarneembaar. Filter erg snel verzadigd?

J'ai acheté une tente de culture bon marché et le filtre fournis ne filtrait pas complètement toutes les odeurs. Pour le remplacer mon choix c'est arrêté sur ce filtre de la marque Vivosun, et maintenant plus aucune odeur ne sort du ventilateur, j'espère que son efficacité pourra durer dans le temps. Je recommande ce vendeur et aussi ses produits :-)

Got it for my bigger vivosun tent after my first grow stunk up the house pretty bad without it , got it all hooked up to vivosun 4inch 195cfm inline fan still provides good air exchange for my girls tho I haven't started to flower in there yet have smoke many bowls in there as well as a cigarette or two due to cold weather an works great for either small to medium grow or smoke room would go with bigger if doing cigar lounge or larger area but very happy an impressed with this company an products purchased thus far
