A percolator, also simply known as a ‘perc,’ is a special glass design that increases water filtration inside of a bong, bubbler, or other water pipes by adding an additional chamber for the smoke to be filtered through. There are many different types of percolator common, but they all serve to improve the water filtration process so your cannabis bong hit is as smooth as possible.

A coffee percolator is a type of pot used for the brewing of coffee by continually cycling the boiling or nearly boiling brew through the grounds using gravity until the required strength is reached. The grounds are held in a perforated metal filter basket.

Coffee percolators once enjoyed great popularity but were supplanted in the early 1970s by automatic drip-brew coffeemakers. Percolators often expose the grounds to higher temperatures than other brewing methods, and may recirculate already brewed coffee through the beans. As a result, coffee brewed with a percolator is particularly susceptible to overextraction. However, percolator enthusiasts maintain that the potential pitfalls of this brewing method can be eliminated by careful control of the brewing procedures.
