Nobody likes smoking out of a dirty bong. Even more than that, nobody likes cleaning a bong. Ash catchers solve both of these problems for avid smokers, creating more time for smoking. If you are an avid bong smoker, then you should be using an ash catcher to keep your bong clean. Your ash catcher will attach to your water pipe the same way you take your bowl in and out. Your bowl will now go into the ash catcher instead of directly into the water pipe. When you take a hit the burned ash will get trapped in the ash catcher instead of passing into the water pipes main chamber.
An ash catcher is a bong attachment that catches ash, resin and other debris, preventing it from entering the water chamber. In addition to keeping your bong clean, ash catchers also provide additional filtration, with cooler, smoother hits. Ash catchers drastically reduce cleaning time and frequency for avid smokers.
