Ever find yourself coughing too much on a hit because it was too hot? Welcome to the world of multi perc bongs and Multi Chambered bongs. Each Percolator adds a level of smoke diffusion which cools down the smoke while also breaking the smoke up into smaller bubbles. So why not add more? More percs = more diffusion and less harsh hits! These percs typically have their own chamber, and having a multiple chambers on a bong can add a bit of restriction to the hit. Shop our full selection of multi chambered bongs with multiple percs!
