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

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!

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!

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.

Great product, as always.

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

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.

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.

THE BEST FILTER MASK THE ODOR SO PERFECTLY AND LAST TOO LONG THANK YOU.
