Works great

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.

I use this as a room air filter for pollen and dust. It works well and ill be replaceing the canister every few months. To me its worth it because i had an air filter for my room but they kept discontinuing the models i bought so these filters an my blower are what i will stick to for the forseeable future.
