I was just about to throw out this filter from a cold brew coffee maker because the carafe broke. Well I got to thinking, maybe this would work as a smoker tube. Well I tried it and it works quite well. I'm getting a steady output of smoke and it is staying lit using wood chips. This is great, now I can use my gas kettle for a quick steak or burger and still get a little smoke flavor without having to fiddle with my charcoal kettle!
