Hon&Guan 8" Air Filtration Kit: 8 Inch Inline Duct Fan with Speed Controller, 16" High Carbon Filter, 16 Ft Ducting & Rubber Coupler, Ventilation System for Grow Tents, Indoor Gardening, Hydroponics

This has been going non-stop on full blast in my 2x4 tent for 2 months now. Absolutely no issues whatsoever. Does a great job of preventing unwanted aromas from escaping and the air circulating. Overall a really great budget inline exhaust unit.

Pain in the ass by yourself (esp if you follow pictures illustration) connect exhaust hose before hanging. The exhaust hose is exact to the exhaust port,some wiggling is almost assured to be needed with it hanging and potentially swaying makes it difficult. That being said it is super quiet, blowing nicely. For my 1st one quite satisfied. Footnote "control hub" gets extremely hot if ran at max for length of time.

So far I’m incredibly impressed. I bought this to use in my grow tent for plants. Other brands like AC Infinity and VIVOSUN charge a ton for their inline fans with filters, and this works great for my 4x2 tent. I talked to a fellow grower who claims to have been using his fan for going on 8 years now! It is a bit loud but I don’t care. Haven’t reached the flowering stage so I can’t say for the smell there but it came with 2 charcoal filter sleeves and I can’t smell it when I feed my plants. It’s made out of plastic but it’s solid and looks good.Edit- i should have purchased the 6 inch inline fan for my 4x2 tent. The 4 inch struggles to keep the temps below 90 with the lights on and 2 oscillating fans running, it just doesn’t pull enough air. Will review the 6 inch when it’s installed and has been used.

Decent budget filter I've had a few this year and they work pretty well never had a issue

For the money it's a really good fan and controller. You can set the time for the fan to come on and off, and if the temp gets too high, low, the humidity changes, they are cycled up or down.

Everything LOOKED fine out of the box. Sleek, cool little fan setup. But once I got everything together, I knew this just wasn't going to work. On it's own, the fan was putting out a DECENT (not great) flow of air, but once the full length of tube was on, what was coming out the end was almost nothing. In NO way was it enough to work for what I needed it for. I didn't find it terribly loud, and for the money, you get a lot, but it just wasn't powerful enough, which I guess makes sense. You get what you pay for.

This is a great system, automatic. Easy setup, I use zip ties to attach it to the top of the tent.

Awesome airfilter! Effective and quiet. Just what I needed for jump starting my garden!
