Bongs are a filtration device used for smoking tobacco and legal herbs. A bong is one of the most popular glass pieces used by smokers to cool down and filter smoke before inhaling. The water inside the bong traps the ash and other heavier particles preventing them from entering your lungs. Glass bongs come in a wide variety of styles, designs, and sizes. Unlike the simple bongs of the past, bongs nowadays contain percolators that provide additional filtration and diffusion by forcing the smoke into tiny bubbles to increase the surface area to promote maximum cooling by the water in the bong. All of our bongs for sale are made from thick, borosilicate glass with a variety of different percolator types and styles. We offer the largest selection of bongs online at the lowest prices to ensure every smoker can find the perfect piece for them.
