Ash catchers are common, staple accessories, and they essentially act as a barrier between your bowl and water pipe. Ideally, to get the most out of your piece’s function, your water pipe should be as clean as possible during use. This level of upkeep can be tricky if you’re a frequent user. Since ash catchers trap debris, they not only ensure your water pipe is kept significantly cleaner, but they also add another element of diffusion to your setup. This added diffusion creates smoother hits and improves function overall.
