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

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.

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.

Just save yourself the hassle and order this one. I originally ordered the "HYDROWE" brand. My room still smells. I was looking through reviews. A guy mentioned he had bought all the brands and AC was the best. So I got one. Smell was gone in 15 minutes. And the flanges are reversible. Would absolutely recommend.
