A recycler bong, also known as a recycler rig, is a type of water pipe that includes a unique recycling feature that helps provide enhanced 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. Recycler bongs are popular among enthusiasts who seek a more advanced and high-performing smoking experience.
