Air Filtration Kit 4” with Speed Controller | Inline Fan and Carbon Filter Combo, Cooling and Ventilation System for Grow Tents, Hydroponics, Indoor Gardening

Awesome, superb quality. This company really cares about quality products. Very quiet at speeds of 1-5, only small levels of noise at 6-10. My bathroom exhaust fan is louder than this though this is moving 4 or 5 times the air with a filter. Would def buy again. Thank you.

We use our 4” cloud line system for our rodent room (we breed rodents as feeders for our reptiles) and the ammonia can build up to toxic levels quite quickly if not exhausted out. The 4” is super quiet and we use it in a space equivalent to approximately 200 SqFt and vent the exhaust outside. It works exceptionally well for our modest collection of 40 breeders (rotated cycles) and anywhere from 50 to 300 grow-outs at any given time. The more grow-outs, the more critical the filter becomes necessary. It works so well, we normally only need to run it for half of the day unless we are sitting on a ton of grow-outs; in which case, we run it at max power all day.

I ended up getting a second filter because hubby thought it smelled. Since then I can run the 4" on lower speed with no smell.

I bought this to add an exaust fan in a small bathroom (5'x8') and it pulls enough to keep the mirror clear even when you take a really hot shower. I like how it saves the speed setting so if you put it on a switch it will turn on to the previous setting. As light weight as it is it pulls a good ammount of air and it is reasonably quiet compared to other can fans I have used before.

Three years old still kicking great product

Expensive but great

Now I ain't got to worry about the smell thank you so much

Fan is sleek, pleasant to look at, perfect for a smaller set up. Works like a champ w very little noise! Highly recommend all the AC infinity products. You can pretty much automate your tent set up with their products! Light, clip on fan, inline fan w/ carbon air filter all hook to one controller super easy to use and worth the extra couple $$s you may spend!

great product

Device works great! Had a major odour issue in my apartment and this device has single handed made the odour go away. Even on the low 2 setting. It is pretty silent for the most part! I love that it comes with the cloth filter as well. Well worth the price.

Great product. The pricing is amazing for what you get. I highly recommend this product.

Seller paid for product to be delivered as quickly as possible, so it arrived sooner than originally stated. Fan is quiet compared to a lot of other fans. Works great with the carbon filter… no smells. Fan has quite a few speed settings, so although it’s a bit noisier as you go up through the various speed settings, it really does shift a large volume of air… and still not unbearably noisy.

Super easy set up, very impressed
