A percolator bong is a bong with one or more percolators – additional filter chambers that pass the smoke through water again. The result is a particularly smooth, cool hit and the typical, rich bubbling sound.
How does a percolator bong work?
After the initial filtration, the smoke is forced through the percolator, where it is broken down into many fine bubbles. More bubbles mean more contact with water – and thus stronger cooling and filtration. Each additional chamber makes the hit smoother, but also slightly increases the draw resistance.
The most common percolator types
- Tree percolator – multiple tubes like branches.
- Honeycomb – a perforated disc for very fine diffusion.
- UFO percolator – disc-shaped with side slits.
How many percolators make sense?
One to two have the greatest effect. Even more chambers will cool further, but make the draw harder and cleaning more complex. For most, a well-built bong with a high-quality percolator offers the best balance of smoothness and airflow.
Frequently Asked Questions
Is a percolator bong harder to clean?
Yes, the additional chambers require more attention. With suitable cleaning accessories, it's manageable.
Is a percolator bong harder to draw from?
Slightly – more filtration means more resistance. The smoother hit compensates for this.
Is the extra cost worth it?
For those who value maximally smooth, cool smoke, yes.
