    • The Ultimate, Sustainable Odor Solution - Perfect for Dialing in the Tent!
Size: 6" Kit
I've been working on dialing in the environment in my 2x2x6 tent for an upcoming Uptown Purps run, and this refillable 6-inch carbon filter from AC Infinity is exactly what I needed. Tackling intense aromas is non-negotiable, and having the ability to just replace the activated carbon instead of tossing out an entire heavy metal cylinder every few runs is a massive upgrade. It perfectly matches the sustainable, hands-on approach I take with my custom living super coco mixes. While a 6-inch filter is definitely robust for a compact 2x2x6 footprint, running it slightly oversized is a brilliant way to maximize airflow efficiency. It allows the inline fan to operate at much lower, quieter speeds while still completely scrubbing the exhaust air. Cost-Effective & Eco-Friendly: The refill kit is straightforward to use and saves so much money and waste long-term. Ecosystem Integration: As always with AC Infinity, the build quality is premium. It hooks up flawlessly with my existing ventilation system, helping me keep my environmental metrics perfectly stable via the Controller AI+. Unbeatable Odor Control: It effortlessly handles the heaviest smells, keeping the surrounding room completely scent-free. If you are running highly aromatic crops and want a heavy-duty, long-term solution that integrates perfectly into a smart grow setup, this refillable kit is absolutely the way to go. ... show more

    • Very high quality everything
Size: 4" Kit
Wow, I thought this was a little pricey at first but seeing the overall quality and included accessories, I am surprised it's as cheap as it is. Everything from the quality of materials, the fit and finish, packaging, instructions, and the customization of the accessories is truly impressive. I used this with a 120mm PC fan and 3D printed duct adapter to filter odors in a Kitty litter box area and it works really well. Very impressed with this company. ... show more

    • No smells
Size: 4" Kit
Completely removes odors, easy to empty and refill. Construction is way better than other brands I've bought. Totally worth the extra cost over non refillable models.

    • Just buy it
Size: 8" Kit
AC Infinity makes the best home indoor growing gear money can buy, and this item is no different. Yeah, you can find cheaper products but I guarantee the level of quality, fit and and finish of those products are not even close to the level of AC Infinity

    • Useful refill kit
Size: 4" Kit
This refillable carbon filter kit was pretty straightforward to use. I like being able to replace the carbon instead of tossing the whole thing, and the size seemed right for my setup. It feels like a more practical way to keep the filter going. There is a little bit of mess just because carbon is carbon, but nothing unusual or hard to deal with. Overall it seems like a good option if you already use this kind of AC Infinity filter setup. ... show more

    • Reusable!
Size: 6" Kit
After throwing away the last filter, it's really nice to know that it's for the last time (minus the carbon). Although the materials between the refillable and sealed filters seem all but identical and the initial cost is almost double, I'm willing to fund the end of throwing away a perfectly good filter (minus the carbon) for no other reason than it was manufactured to be replaced. I've had several issues with AC Infinity in the past, frim my oscillating fan (before the updated version and they replaced it without request, just sent me an email saying I could get a free replacement/upgrade!), the tent with pinholes, some changes to how they worded their return/replacement verbiage on their website and questionable responses to the light issues I had, this is a must have, in my opinion. Since I'm unaware of any other manufacturer selling refillable in-line filters, this decision was a no-brainer for me. ... show more
