What does a percolator do in a bong?

Percolator bongs are becoming more and more popular, if not the standard. So you might be asking yourself, what do bong percolators do? Perc bongs diffuse smoke through water by creating more surface area. As smoke travels through the bong percolators it creates bubbles that cool the smoke down and remove debris. 

Bong with percolator vs without

Whether it’s a honeycomb, jellyfish or faberge egg perc, the experience between a bong with percolator vs without is monumental. 

Most bongs have a slitted downstem by default so you are probably already familiar with the additional diffusion that it produces. Diffused downstem have small slits along the bottom third which allow smoke to pass through water and cool down.

Similarly, glass bong percolators diffuse and cool smoke, however, their shape, placement and number will affect their efficiency, visual effect and the aesthetics, of course.

Bongs with percolators produce a hit that is overall much smoother for two reasons. Bongs with percs force cannabis smoke to travel through more bubbles within the water. The increased surface area gives the smoke time to cool and also removes harmful contaminants.   

How many percolators is ideal?

Too many percolators can increase drag making it harder to rip, so it’s really about striking a balance. A triple or quadruple perc bong may be good for people with lungs of steel but for most of us it’s excessive. It will increase drag significantly and take away from the experience. 

Also, pieces with lots of percs stacked one over the other tend to be more difficult to light, handle and clean. So if you’re just starting out with your first percolator bong or are looking for ultimate comfort, it’s best to start with a piece with less percolators. You can always work your way up to more complex pieces over time as your lung capacity increases. 

These larger pieces are also less travel-friendly so if you’re looking for a portable percolator bong, go for one made from thick borosilicate glass with just one to two percs.  

Do percolator bongs get you higher?

Actually, since percolator bongs have an extra layer of filtration, a small amount of THC is lost compared to bongs without percs. Most stoners do not mind this though because they choose perc bongs for the experience. They prefer cooler, filtered hits because it’s easier on the throat and removes more impurities from the smoke than bongs without percolators.

And, because the smoke is condensed as it travels through the percs and chambers, you’re able to take fatter rips. So essentially, the loss in THC is counterbalanced by the additional silky smooth hits you’re able to take in one go. 

Bong percolators 101

There are many different types of percolators for bongs. They all work to filter and cool smoke but their unique shape produces a slightly different effect. Here are the most common:


The honeycomb percolator is a type of disc perc and is perhaps the simplest style. It offers a good level of diffusion with minimal resistance. Its circular shape fits perfectly in the neck of most straight tube bongs so it integrates seamlessly. Each disc features honeycomb perforations throughout which maximizes the amount of smoke that can pass through, delivering solid filtration with almost no drag. Since this style doesn’t provide as much diffusion as more complex styles like the tree or matrix perc, honeycombs tend to be stacked one on top of another to compensate. Honeycomb percs are also one of the easiest styles to clean given their flat pancake shape.


Turbine percs, also known as cyclone percs or vortex percs, look a lot like honeycombs but deliver a completely different effect, especially when it comes to the visuals. Their circular shape features angled slits along the edge of the disc that direct water and smoke in a whirlpool fashion so that it looks like a mini tornado. The effect is multiplied the more turbine percs you have; the smoke is pulled through the mouthpiece and the water and smoke converge towards the middle forming a vortex. 


While some define tree and jellyfish percs as their own distinct style, others often use the terms interchangeably. This style of bong perc resembles a tree or jellyfish. The top looks like the head of a jellyfish followed by tentacles or branches beneath. Tree percolators offer the best diffusion of all bong percs since the smoke has to travel up through each arm before it can pass through the neck of the water pipe to the mouthpiece. And while tree percolators offer second to none filtration, they require a lot more maintenance than most styles. 


This style bong perc is shaped like a treaded tire turned on its side. Matrix percs offer great diffusion yet are much easier to clean than tree percs since they aren’t nearly as intricate or fragile. While they offer slightly less filtration than trees, they have roughly the same resistance. Their straightforward design also makes them more robust and less prone to damage when removing residue. This style bong perc is ideal for people who want optimal diffusion with less maintenance. The only catch is that the grid style is more susceptible to extremely small bits of ash and debris getting trapped. It’s just the nature of the beast. Nothing in life is perfect.


Showerhead percolators are essentially a simplified version of the matrix style. They have the similar tire shape of matrix percs but do not feature the intricate grid. Instead, they are smooth with radial slits or holes along the bottom. This means that they don’t offer as good diffusion but are easier to clean. However, the real difference has to do with the fact that they have significantly less holes. So naturally there’s increased resistance and with that, more drag.


Inline percs often vary in size but generally have a tube-like shape with slits along the sides. It’s another simple style that’s easy to clean. They offer similar diffusion power to the showerhead perc, as well as comparable drag.


Spiral percolators, also known as coil percs, offer a unique visual effect compared to other styles. As water travels through the spiral, larger bubbles emerge around the loops of the coil. And puffy clouds of smoke rise and mushroom above.

Fab egg 

Fab egg rigs started out exclusively as dab rigs but expanded to bongs in part for their unique aesthetic. Originally known as faberge egg rigs, this style bong consists of two chambers, one for diffusing smoke and another for percolation. The fab egg perc pairs perfectly with the Swiss perc with its larger holes to create lots of diffusion. 

Diffused Downstems

Most water pipes feature a diffused downstem. The downstem is the piece that slides into the joint of a bong. It’s what directs the smoke from the bong bowl into the chamber at the base of the bong. The multiple slits along the bottom edge break up the smoke particles so it comes into more contact with water.

How to fill a bong with a percolator

Figuring out how to fill a percolator bong can be a challenge early on, especially since every piece is different. Some percolated bongs are itty bitty with just a single perc while others are huge with multiple percs and chambers. Each percolator is unique and so is your preference but the most important thing is not to get dirty bong water in your mouth. 

How to fill percolator bong

You can fill your percolated bong through the joint or the mouthpiece. We recommend the joint because you have a bit more control over how much water you put because you naturally have to pour it more slowly. We also recommend using a cold water bottle from the fridge since it’s easy to pour and will cool the smoke further.

How to fill up a honeycomb percolator bong

In general, you want to emerge the percolator fully. For instance, if you have a single honeycomb percolator bong, the water should be filled slightly above the disc. Some people prefer it slightly below but you’ll just have to try it out for yourself to see what works best for you. 

Ideal percolator bong water level for multiple percs

However, let’s say you have a triple percolator bong spread out evenly followed by an ice catcher and the neck leading to the mouthpiece. In this case, you’ll want the water level to be just above the second perc. 

Test it out. the water should reach the third percolator without splashing into your mouth when you take a test hit.  If you get anything in your mouth, pour it out. Test it out again, so you know if your level is correct before taking a real hit.

How to clean a percolator bong

Cleaning a percolator bong is much like cleaning any other bong, except more time consuming since you have to give extra care to the percolators. Some percs are robust, while others are more fragile. For instance, tree percs are notoriously difficult to clean, while honeycombs are a cinch. 

Regardless of what style you have, here are the easy steps to take care of your piece so it’s sparkly clean with minimal effort.

  1. Disassemble your perc bong.
  2. Pour isopropyl alcohol through the joint until before it’s about to spill out from the bottom of the joint.
  3. Put a few spoonfuls of epsom salt through the joint 
  4. Close off the joint securely with a few layers of plastic wrap and rubber bands so the isopropyl alcohol doesn’t spill out.
  5. Continue to fill through isopropyl alcohol through the mouthpiece leaving a little bit of space at the top for some air that way the liquid has room to move.
  6. Add a few more spoonfuls of salt through the mouthpiece.
  7. Close the mouthpiece with a few layers of plastic wrap and rubber bands so all holes are capped off and nothing leaks out.
  8. Turn the piece upside down, rotating it a few times slowly so that the salt gets evenly distributed.
  9. Let the mixture soak for a while. Everyone says something different but our rule of thumb is 30 minutes.
  10. Place one hand over the mouthpiece and the other palm holding the base with your thumb covering the joint and shake softly to break off any caked ash and resin. Remember, this is your baby after all.
  11. Once you see most of the resin has become dislodged and is floating around instead, dump out the mixture.
  12. Rinse thoroughly with warm water until you no longer smell the isopropyl alcohol. 

Percolator attachment for bongs

Bong percolator attachments, more commonly known as ash catchers, are becoming more and more popular since they are one of the best ways to remove debris while keeping your water pipe clean. Essentially, since smoke travels through the ash catcher first, it catches much of the ash and other contaminants before it even reaches your bong.
