AC InfinityRefillable Carbon Filter Kit 6” with Additional Refill, Odor Removal Air Scrubber For 6" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics

After opening...Wow! Price I felt was a little steep, but its worth it! This is quality! It feels soooo good when you hold her and even better when you slide her dress on...aka the pre filter. And it came with 2 pre filters. I thought it was only one, but it comes with everything plus the comfort of knowing you have a quality product and if it's not they will make it right. Unlike 98% of these vine reviews, I paid out of pocket so I might be a little biased lol, but don't hesitate to get the refillable one. The refill bag is huge too, but it is supposed to fill up the 6 inch filter one more round. Overall, I'm throughly impressed and felt like money well spent. Only thing I think would've made it 7 stars instead or 6 lol...would be some nice AC infinity stickers. Love the cool stickers that are out there. Great job AC!

Over a month into flower in a 4x4x6 tent, venting into a different room in the house. Zero odor, really does an incredible job. Worth the extra $$ for the reusable.

Great idea and value

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.

i have attic. cleared all my smell issues. paired with their in line duct fan. works great.

It was easy to install, and it's easily refilled with zero problems. Works fantastic! What a difference! A little expensive but worth it for being able to refill the carbon medium and filter. I would recommend it for sure!

This filter has exceeded all my expectations! Being able to change the carbon is a game changer! The other filters on the market are wasteful.The build quality is fantastic! It comes with two pre filters so you can easily swap them out, keeping it clean. Most importantly, it removes smell really well! I think even better than the other larger filters I’ve bought in the past.If you’re looking for a new carbon filter for your grow. Do yourself a favor, buy this reusable one!

Since this is renewable it makes it a great value. Filters are getting expensive and this helps eliminate some of that.
