AC Infinity Air Carbon Filter 4" with Premium Australian Virgin Charcoal, for Inline Duct Fan, Odor Control, Hydroponics, Grow Rooms

AC Infinity just does a nicer job on their stuff. Any old carbon filter does the job. AC Infinity puts a couple loops on the case because they know you'll be using a hook. Nice work!

The AC Infinity Air Carbon Filter is a game-changer for anyone looking to improve the air quality in their home or workspace. This carbon filter is a must-have for anyone who wants to eliminate odors, allergens, and pollutants from their indoor environment. First and foremost, I was impressed by the cutting-edge technology used in this filter. The activated carbon filter effectively removes odors, smoke, and harmful chemicals from the air, leaving behind a clean and fresh-smelling environment. I noticed a significant improvement in the air quality within just a few hours of installing the filter. Another standout feature of this filter is its versatility. It is compatible with a wide range of AC Infinity products, making it easy to integrate into your existing air purifier or ventilation system. The filter is also easy to install and replace, with convenient features like a built-in flange and pre-filter wrapping. In terms of durability, the AC Infinity Air Carbon Filter is top-notch. The filter is constructed with high-quality materials that are built to last. The carbon layer is thick and dense, ensuring long-lasting performance and effective filtration. Overall, I would highly recommend the AC Infinity Air Carbon Filter to anyone in need of a reliable and high-performing air purifier. It is a great investment for anyone looking to improve their indoor air quality and create a healthier living environment.

Works great if you have dogs or smoke

My whole house was loud from the moment you got 20 ft from the door. Installed this filter, aired out the house. The smell was gone within an hour or two and hasn't returned. Pretty impressive considering I just harvested so the smell would be at its peak. I love how they put hooks for easier installation and a lot lighter than the previous one I bought and paid more for. Hoping to get at least a year out of it minimum, will report back.

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.

Massive. I bought it with a matching ACI exhaust fan just to scrub the lung room when in there with the tent open. Ended up placing it inside the tent to help more from leakage. It has helped some but not nearly what I expected from nearly 800cfs and the size which comes with extra expense. It's been running a few weeks now so not sure on longevity. I will say my ACI carbon filters haven't lasted as long as I expected. The 6" that is feeding from tent to attic stopped filtering well after only 3 months in the same grow this is in now. I've had better lifespan from cheaper brands but like the build quality and ACI ecosystem (for most things). I'll eventually crack it open to see I can replace the carbon or have to grab a made to be refilled one.

Extremely excellent product!!! Easy to install. Airflow is great .

Wow. I should have gone with AC Infinity brand gear from the get-go. I'm kicking myself for not buying AC Infinity initially. This carbon filter is real nice. Especially if you're used to the cheap Amazon brand ones, like iPower. Not only is it made ALOT nicer, I think it works better too. I don't know about how long it'll last, yet, but if I had to make a guess, I'll still be using this carbon filter in late 2026, if not longer than that. Arrived in good shape and super fast too. I cannot recommend AC Infinity brand stuff enough. If you're spending your money on the lower cost brands, you'll actually save money by only having to buy once, instead of multiple times in the same time period. So, plz, stop wasting your money on lower cost brands, like iPower. I promise you that you'll wind up spending less, over time, buying AC Infinity.

Llego con todo el carbono esparcido y con los filtros rotos.

I can’t speak for others but, I’ve been reluctant to pick up a filter online due to all of the horrible reviews. 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.

Der beste AKF den ich bis jetzt gekauft habe. Sehr gute filterleistung es ist keinerlei unangenehmer Geruch in der gefilterten Luft. Nicht übertrieben gross nicht so schwer und lässt sich dank hängeösen aufhängen. Die beigelegten Aufhänger zum ferstellen der Höhe haben eine super Qualität richtig stabil. Wer die schon benutzt hat weiß was ich meine. Akf von AC in... super würde ich immer wieder kaufen.

Delivered this morning installed in minutes absolutely incredible a major upgrade on my previous carbon filter. This is a game changer. Humidity dropped within seconds and extraction is on point. Highly recommended and incredible value for money.
