A percolator is an additional water sub-chamber within the shaft of a water pipe which increases the water filtration process, helping to cool down the smoke for a smoother and thicker inhale. It allows two levels of water filtration using pressure to increase the smoke-water interaction process, making the smoke to rise evenly and in a cooler form.There are different types of percolators coming in various shapes, sizes and designs perfect for every bong.
