Ash Catchers are an excellent way to add extra diffusion and filtration to your glass dab rig, bong, water pipe, and simultaneously keeping your water and smoking piece cleaner for longer. The removable attachment is available in different shapes and styles and some offer an extra percolator inside of the catcher. In addition to filtering your water and providing more diffused hits, they can be an inexpensive way to upgrade an older or plainer style bong. The ash catcher catches the reclaim, resin and ash leftover from your hits and helps to cool your smoke before inhalation. Available in both 14mm and 18mm sizes, ash catchers come in 45 and 90-degree angles as well to perfectly fit your individual piece.
