A recycler bong & recycler dab rig is a type of water pipe with a unique recycling feature that helps enhance filtration and smoother hits. The main purpose of a recycler is to continually cycle the water and smoke through a series of chambers, allowing for maximum diffusion and cooling and resulting in a smoother and cleaner hit. It also helps to prevent the water from becoming stale or stagnant, as it constantly moves and mixes with the smoke.
