Industrial Air Purifiers, Odor Control for Industrial and Commercial Use

My 6 inch max-fan won't fit in the hole. I'll just use tin tape to secure. It works good though even on a low power fan setting. Cleaning air. I can totally tell a difference. I bought 2 of these filters. The other is on a 8 inch fan dialed down. I'm hoping for at least four months out of them. Time will tell. I might put timers on for them to turn off from 1 am to 4 am. That'll make the filters last longer. These are easier to dispose of too other than the bigger ones. Cheap too.

My neighbors complained about the smell form my greenhouse so I told them I would look into venting my grow up a 25' pipe to keep the smell away did some searching and found these. I figured I would try it because of the low cost. It's working so far 100% of all my 6x6 greenhouse is vented through one of these it doesn't completely kill the smell but it's darn near 70- 90% I don't have strains that have extreme smells if I do I'll get a Y pipe and install two same time. 2 months so far so good. the unit is held together by rivets that can be drilled out and replaced with screws to reload.

The 6" works alright at lower CFM but lets some stink through at the higher CFM I need to keep my tent at optimal temp. Don't have this problem with the Can Fan filter but those are almost 4x the price of these. The 8" seems to be filtering fine.

I waited a little bit to test it on 2 flower stages and it keeps the smell down wonderfully. I was afraid this was a work once and done but nope, still working great. I will be buying another one soon for another room.

Bigger than I thought but value for money is good.

Cfm was a bit under for what my 4" hurricane puts out,other than that the carbon is escaping into the center causing it to be less effective

EDIT: this can filter never worked very well from day one. It was my fault for not noticing that this filtet was not reversible. Much better options in the same price range availableSo after 8 months I'm chucking this out this didn't work well almost from the beginning, I could still smell unfiltered smells whereas the prior filter which lasted much longer, worked flawlessly with no odor leaks so I'm not buying this brand again.

Works great to reduce smell from greenhouse or grow tent, great filter at a great value, i recommend a good blower with power adjustment to get it just right!
