Jean: Removes all the smell and seems durable.

Minus 1 star for the incredibly tight dust sock, that thing took more than 5 minutes to force over the filter.

Kearstin: Keeps my house smelling normal. We are indoor canabis growers and have always stopped growing in winter as we cannot have the outake fan venting outdoors in -30*c. We finally tried these filters, they work great. Have been growing for a few months now and still no smell. Worth the money.

THOMPSON: the only thing I would change is the way it is hung. I like the direction many of the other manufacturers are going in terms of having a couple of metal hangers instead of straps. I know that is what I will be looking for on my next replacement purchase.
It does a good job filtering orders and the price is not bad.

wPublicName: I have purchased 2 of these actually. The first one was fine. The second one leaked air from the top where the flange for the vent attaches to the filter media itself.
One nice thing about the filter is that you can technically disassemble it, which I did for the leaky one, and put in a gasket (made of the packing material for the filter actually) which stopped the leaking. Having to do this is the only reason its not 5 stars. Had I not realized that it was leaking it could have been awkward.

Despite being able to mostly disassemble this, you can't replace just the media, at least not with media of your own. If/when the charcoal becomes ineffective, plan on replacing the entire unit. I have been using my older one for about 6 months for filtering cigarette smoke and seems to be about as effective now as it was on day 1. I don't know how this translates for other filtering purposes.

Specifically about smoke. This filter's primary intended application is likely not for smoke. Smoke has particulate that a charcoal filter alone shouldn't be expected to remove.
That said, the air coming out of the filter (with no modifications) appears clear, but you can still smell...
