It is still filtering smoke just fine. So a month of semi regular use
So this thing does exactly what it's designed to do. You blow smoke into it, and you can't smell much coming out. There's still a little smell if you're smoking up in a small room, but that's mostly due to the product itself and not the smoke you're exhaling. Although I did notice after about a month of semi-regular use (a few times a week.) it started getting this really nasty smell. Now let's be honest, that's probably from my own munchie breath blowing into the thing constantly, but I was surprised at how quickly an odor formed. I left the caps off - as some of the other reviews said, but it still formed an odor. There's really no washing instructions, so I tried spraying a tiny bit of air freshener in there to see if it helped freshen it. (I waited until it was fully dry to use it.) but it still had a weird funk.<br /><br />HOWEVER, It is still filtering smoke just fine. So a month of semi regular use, and it still gets the job done, but has a weird funk.<br /><br />For $11, I feel I got good use out of it.
