However, I have some AC infinity grow tents, and I’ve been happy so far with the quality of them, I decided to pick up this filter and give it a try. A few things to mention here. Size of these filters matter per grow tent size, so if you’re one of the ones trashing this product, 100% you’ve gotten one too small for your grow room, or you’ve picked up a crap inline fan, fans matter too. I bought a 4inch filter that is more than enough for my 3x3x7 mother plant grow tent. No smells, and it offers a nice stealth grow in my home with no smells, nada, nothing. Typically these filters last anywhere from a year to two years depending on how much you use them, and how many grows you do. For 4x4x6 tents I’d recommend at the very least a 6 inch filter, and 5x5 tents at the very least an 8 inch. I currently have another tent that’s a 4x4x6 running a 10 inch filter and it’s complete overkill.Anyway, if you’re hesitating on grabbing one of these, don’t, this product is solid. AC infinity for the most part have a great reputation in the home growing field. ### ⭐⭐⭐⭐⭐ Works incredibly well! *by on Reviewed in Canada 13 May 2026* This unit far exceeded my expectations. I was expecting a reduction in odour. However, I was actually shocked and very pleasantly surprised to find absolutely ZERO odour coming out of this filter. It has literally 100% eliminated a stinky problem. I have it at the end of an exhaust pipe, with the pre filter bag inside the unit. A 12 volt 80mm fan has no trouble pushing air through it ### ⭐⭐⭐⭐⭐ Another AC Infinity product I'm happy with.. *by on Reviewed in the United States 8 February 2022* I have what is essentially a grow tent, except I don't grow anything in it and sleep in it instead.Because the air in there automatically gets thick n' clammy (like a good chowder), I bought an AC Infinity.. uhh.. T series? S series? The one that HAS the electronic control stuff-- inline fan. I also bought some of their ducting, and then used some generic 4" bits and pieces to make stuff work to pump fresh are into my sleeping pod.However, I noticed that I was waking up, kind of often, with a pretty bad smell in my nose. Sometimes, I'd know what it was, other times not, but I bought one of these filters for the intake side, and I'm able to draw in air from my room and give it a nice fresh non-scent. It hasn't messed with airflow too, too terribly, and I am still able to pick up air conditioned air when I want it by placing the filter at the outflowing vent of my AC.The first day or two, the non-smell in my room (basically, a smell unto itself-- almost sweet) was intoxicating. I also noticed-- as dumb as this will sound-- that the air felt smooth, as though it was almost too easy to breathe.Long story short, I'm very pleased, continue to be impressed with AC Infinity (I have a few of their hobby/kit fans, also) and find all their stuff well worth the money. ## Frequently Bought Together - AC Infinity Air Carbon Filter 4" with Premium Australian Virgin Charcoal, for Inline Duct Fan, Odor Control, Hydroponics, Grow Rooms - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity CLOUDLINE PRO T4, Quiet 4” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/395768547-ac-infinity-air-carbon-filter-4-with-premium-australian-virgin](https://www.desertcart.tn/products/395768547-ac-infinity-air-carbon-filter-4-with-premium-australian-virgin) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-11*
