Fact Checked by Doctor NameA Swiss perc is a specific type of percolator design often found in water pipes and bongs.
Named for its resemblance to Swiss cheese, the Swiss perc contains a disc with multiple holes that smooths and filters smoke.
This percolator is known for providing very cool, smooth hits from cannabis smoking devices.
What is a Swiss perc?
A Swiss perc refers to a percolator diffuser inside a bong or dab rig that contains a flat disc punctured with numerous holes.
As smoke passes through these holes, it gets broken up into multiple micro-bubbles.
This diffuses the smoke and optimally filters it through the water, cooling down the temperature considerably.
The resulting puff of smoke is extremely smooth, making large hits from small rigs possible.
The tiny holes perforating the flat disc resemble Swiss cheese, leading to the name Swiss perc.
They provide highly effective percolation for smoking devices across many budgets and sizes.
