Review: 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!
Review: 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.

A: Available on Amazon too - https://www.amazon.com/AC-Infinity-Pre-Filter-Replacement-Hydroponics/dp/B09DR8LGV4

A: I've been using the same filter since "Last purchased Jul 10, 2020." on a 400cfm fan dialed down half way I only use LEDs. I haven't even flipped the flange around yet even and it still working awesome.
