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!

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

Great product, as always.

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.

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

I upgraded my dust collector system to also have one port that was a fume extractor for welding. I upgraded the filter to a 0.2-micron Hepa filter, but I still needed a carbon filter to remove any VOCs So I thought I would give this a try. I must say I am impressed with how well this works! there is zero smoke in my airconditioned shop, even after welding for hours! Just for fun, I thought I would see how well the system would remove paint fumes... I have a cabinet I was working on, and so I turned on the system and sprayed lacquer on the cabinet, 4 coats. I left the system running for about an hour after I was done, because I was not spraying under my fume extraction hood, but I was halfway between the dust collector exhaust and the carbon filter, so the air had to get from one to the other and go right past my spray area. When I went back out to shut off the system, I was surprised that it did not smell like lacquer at all! Normally when I spray lacquer in my shop, even the next morning there is a strong smell of lacquer, it takes over 2 days to fully dissipate, but this filter removed all trace of it in less than an hour! I've used it to remove the lacquer fumes on several other occasions and it's worked very well each time. I'm really amazed at how well it removes the VOCs from the lacquer as well as the fumes created by welding. It's a great addition to my shop that allows me to work in air-conditioned comfort while also enjoying clean air.
