Keep it clean (50-50% Smoke Soap) in a gallon ziploc, and this piece will be your go-to. Buy two, so you will always have a clean piece ready. Also add five drops of Resin Block to any new refill. You will be amazed at the tar this piece screens and guards your lungs from. Simple design, Super results. I only wish it came with a couple of glass daisies, but Ebay has plenty of those.
