An ash catcher is a bong attachment that, as the name indicates, traps dirt, debris, ash and resin before entering your bong. An ash catcher adds another layer of filtration that will significantly reduce the need to clean your bong (although not eliminate your bong cleaning duties), and generate cleaner, cooler smoke to enjoy. There are 3 main types of ash catchers: Plain, Diffusers and Percolators. All have bowl or a female joint to connect to a bowl, a chamber and a joint to connect to your bong. Want to know more...
