Put this on the exhaust of my 6” fan. It handles the exhaust of 2 grow tents. No smell at all until I open the tent. And I’m talking DANK.

This is my second or third one of these. It does a great job of removing the plant odors from the exhaust, and I've been able to use each one for 2-3 grows in a 4X4. Recently I tried replacing the carbon and charcoal in one, and while I was successful I spent almost as much as a new one of these costs.

Odor elimination lasted about 12-14 months removed the endcaps and switched them around and odor reduction lasted another 6 months, I put the filter in a metal barel and lit a hot coal fire under it, it released a ton of smell and was good for yet an additional 6 months using both sides, on daily use in dusty conditions. After over 2 years i could not recharge it by heating it above 500 degrees. Ordered again, so far zero odor, running 24/7. Make sure you shake it out and its not pointing in the direction of anything white,as some fine carbon dust shoots out the fan for first minute or so which happens with most of these type of filters. Works best with an inline fan, the white cloth dust cover it come with helps preserve the carbon's life so use it.

This is the first filter I've purchased so i dont have much to compare to, but it does exactly what I need it too. I have it in a small (4'x8') indoor grow room hooked up to a 6 inch inline fan that pulls a max of approx 500 cfm. The fan isn't even on 50% and there is absolutely no smell outside the room or the house. I even put my nose to the exhaust vent and couldn't smell anything. Like I said, I may not have a lot to compare to, but this filter filled all my needs and more. I did also buy some prefilter material and wrapped the outside. I'm not sure if this was necessary or not, I haven't tried it without.As far as life expectancy goes, I've only been using it for a few months and I'm not sure how long it will last. As of now, I see no signs that it's wearing out or in need of replacement. The prefilter is starting to collect some dust and inlay replace thsr

Works very good and does exactly what it's supossed too. As others have stated, be sure to check the size measurements, this unit is prolly bigger then you think it is.The missing star is for its price. For what it is and the materials used, I can't really see why this costs so much. This comment is directed at filters in general and NOT this particular brand. I would remove 1 star from ANY filter in this price range or above it, (regardless of brand or manufacturer) for this reason alone, so this is not a specific indication of how this particular brand or item performs.That being said, it arrived on time and in good shape. This was a solid purchase and a solid product. Would buy again.

I gotta rave about this filter. I read into filters pretty thoroughly before buying and have been using Carbon Filters with inline fans for years to get rid of strong smells. The last one I had before replacing it with this filter measured 22 inches long so this filter is a baby compared to it. The last filter was rated for 475CFM while this one is supposed to be 400CFM. My 6 inch inline fan is 435CFM but I run it on a fan speed controller. Filter came boxed up great in a plain cardboard box that said it was from china but didn't describe the contents (thankfully). Great packaging to keep it safe and keep any carbon from making a mess once you open it. CAUTION: OPEN OUTSIDE so you don't make a mess you regret inside. There wasn't really that much dust but i did tilt it around carefully not shaking it but just making sure it got anything that was loose off before hooking it up. Once it was hooked up to my 6inch inline fan via 6inch flex ducting I turned it on about 90% of the way with my fan controller. Not much carbon came out so I was happy. This filter seems to have a very generous amount of active carbon packed inside it because I smell absolutely nothing. It's not restricting my fan any more than the old, much longer filter i previously had. This thing filters out completely all the smell from what I can tell. Even smoke is cleaned out of the air. Works great suspended in the air sideways or sitting on something standing up. It is also reversible so after 3-4 months of heavy use I plan on taking the bottom off and reversing the top and bottom so all of the active carbon gets utilized before it has to be replaced. Most filters are riveted so that you can't do this. Also note this filter comes with a prefilter that must be stretched over the filter so bigger particles of dust don't get sucked up into the carbon blocking air flow off. You NEED to clean this thing about once a month in hot water to rinse the junk out so the filter doesn't prematurely go out. Takes literally 5 minutes at most to do.

Came packaged well. After reading some of the reviews I was expecting a huge amount of carbon dust to be everywhere but that was not the case with mine. No fine dust, just a small amount of carbon granules that had come out of the middle - shop vac down the middle of the filter cleaned it right up. I hooked it up to the inline fan outside with a piece of air conditioner filter between the carbon filter and fan just to let it clear out completely (the filter only caught a bit more carbon), took it back inside and hooked it up and haven't noticed any more escaped carbon.Tested it by smoking half a cigarette in the room with it running (no one smokes inside) and no one else could smell any cigarette smoke or odor after I put it. Will update over the longer-term if it fails at odor control but from what I can tell so far it's working well.Construction, materials, and tolerances are fine - nothing to complain about at all. Removable/switchable flange and cap to extend its life is a plus (and would allow a person to refill the carbon themselves if so inclined).
