It’s a filter!
Well it’s a filter and it does its job but it’s AC infinity so it looks pretty too. This thing is sturdy and easy to clean or swap out the filter material so it’s a huge plus over my last one. It has a good seal against my AC infinity fan and they’re both super quiet together. Helps keep the stank in the grow room to an acceptable level - solid product from AC infinity as always!

Nice product.
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!

Eliminate strong odors in your grow
Eliminates even the dankiest odors. It’s like magic. The pre filters do a great job catching small particles.

Another AC Infinity product I'm happy with..
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.

Good build quality, ACI aesthetics, and it's massive
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.

How to mount your filter outside of your tent
This is my first AC Infinity filter. I mount my 6" filter (and fan) outside my grow area. At first the smelly air was running from the inside of the filter to the outside. The air still smelled! So I built a 'Reverse Intake Box' out of a 5- and 3-gallon bucket (and a funnel), so the air travels through the filter from the outside to the inside. No more smells. Don't know how long it will last, but other brand filters usually last 3 to 6 months.

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.

Hatte schon diverse AKF von verschiedenen Herstellern und dieser hier ist mit Abstand der Größte und qualitativ am hochwertigsten Wirkende Filter, den ich in der Hand hatte. Auch dad umfangreiche Zubehör kenne ich so von anderen Herstellern deutlich dürftiger. Funktions- und Geräuchstechnisch habe ich ebenfalls Nichts auszusetzen.

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.
