Percolators Explained: Types, Benefits and How to Choose the Right Bong Perc
Share
Percolators are one of the most talked about features in glass bongs.
If you've ever thought what a bong percolator actually does, whether a matrix perc is better than a honeycomb perc or if a recycler is worth the extra complexity and cleaning, this guide is for you. We will explain how bong percolators work, the differences between popular perc styles and how to choose a setup that suits the way you actually use your glass.
Whether you're buying your first bong or upgrading your setup, understanding percolators will help you make a decision which is best for you.
What Are Percolators? (Quick Answer)
A percolator is a filtration feature inside a bong that breaks smoke into smaller bubbles as it passes through water. This process is known as diffusion and increases the surface area between smoke and water, helping cool and filter the smoke before it reaches the mouthpiece, then your lungs.
Different percolator designs achieve this in different ways, which is why some bongs are smoother or easier to clear than others.

What Is a Bong Percolator?
A bong percolator is an additional filtration chamber built into a water pipe.
Simply to create more diffusion.
Instead of producing a few larger bubbles, a percolator breaks smoke even more into dozens or even hundreds of smaller bubbles. This increases the surface area and allows smoke to have more contact time with the water.
The result is typically:
• Cooler smoke
• Smoother pulls
• Improved filtration
Percolators come in many forms, including matrix percs, honeycomb percs, tree percs, halo perc, showerhead percs and recycler systems.
How Do Percolators Work?
The short answer is diffusion.
When smoke passes through water, it cools naturally, add a percolator and it cools it even more by creating more bubbles.
More bubbles mean more surface area.
More surface area means greater and longer contact time between smoke and water.
Different percolator styles create different bubble patterns, which is why airflow and draw resistance can vary significantly between designs.
This is also why some people prefer a simple showerhead perc while others enjoy the dense filtration of a honeycomb or matrix setup.
Common Percolator Terms Explained
Diffusion
The process of breaking smoke into smaller bubbles within water.
Airflow
How freely air moves through a bong during inhalation.
Draw Resistance
The amount of effort required to inhale through a bong.
Splashback
When water travels up the neck of the bong during use.
Filtration
The cooling effect created by passing smoke through water.
Recycler
A multi chamber system that continuously cycles water during use.
Percolator
A glass structure designed to increase diffusion inside a bong.
Types of Bong Percolators Explained
Matrix Percolator
The matrix perc is one of the most popular percolator designs available today.
It uses a cylindrical chamber with multiple precision cuts around the outside. These cuts create a large number of bubbles while maintaining relatively open airflow.
Best for:
• Everyday use
• Balanced airflow
• Strong filtration
• Users who want an all round performer
Things to consider:
• More cleaning than a simple straight tube
• Slightly more drag than an inline perc
Honeycomb Percolator
Honeycomb percs use a flat disc containing dozens of small holes.
This creates extensive diffusion while keeping the design relatively compact.
Best for:
• Maximum filtration
• Smooth draws
• Compact pieces
Things to consider:
• More difficult to clean
• Can create more draw resistance
Split Matrix Perc
The Split Matrix Perc is a modified matrix-style percolator designed specifically for smaller rigs.
Traditional full matrix percs can sometimes create excessive bubbling on compact setups, especially when paired with a wide open mouthpiece. To control this, many smaller rigs reduce the mouthpiece size or airflow opening, but this can make the draw feel tighter and less natural.
The Split Matrix design takes a different approach.
By partially closing off one side of the matrix, it creates more controlled water movement while reducing over-percolation and excessive bubble stacking. This helps minimise splashback while still allowing a full-flow mouthpiece and more open airflow.
The result is a smoother, more balanced hit without sacrificing airflow or usability.
Best for:
•Smaller rigs
•Open airflow
•Reduced splashback
•Balanced filtration
•Users who dislike restricted draws
Things to consider:
•Less diffusion than a full matrix perc
•Designed to prioritise balance rather than maximum filtration
Perfect for dabbers and flaovour chasers
Tree Percolator
Tree percs use multiple arms branching from a central chamber.
Each arm contains slits that diffuse smoke independently.
Best for:
• Traditional percolator setups
• Strong filtration
• Larger bongs
Things to consider:
• More fragile than some modern perc styles
Showerhead Percolator
A showerhead perc uses slits around the base of a vertical tube.
It's one of the most practical and beginner-friendly designs available.
Best for:
• First-time buyers
• Easy cleaning
• Reliable airflow
Inline Percolator
Inline percs use a horizontal diffusion tube positioned inside the water chamber.
They are known for smooth airflow and low draw resistance.
Best for:
• Open airflow
• Straight tubes
• Recycler designs
Recycler Systems
Recycler bongs continuously move water between chambers while inhaling.
Rather than relying on a single stage of filtration, they keep smoke moving through fresh water repeatedly.
Best for:
• Cooling
• Flavour
• Dab rigs
• Experienced users

How Do You Choose the Right Percolator?
Best for Beginners
A Showerhead Perc is often one of the easiest places to start thanks to its balance of airflow, filtration and simple cleaning.
Best for Everyday Use
Matrix and Halo percs offer strong all-round performance without becoming overly complicated.
Best for Maximum Filtration
Honeycomb percs create a large amount of diffusion and are popular with users who prioritise smoother pulls.
Best for Balanced Airflow and Filtration
The Halo Perc was designed to create a more balanced smoking experience by reducing excessive bubble build up compared to a full matrix perc.
Rather than maximising diffusion at all costs, the half-matrix design helps maintain smoother airflow, easier clearing and less splashback while still providing strong filtration.
Best for Cooling
Recycler systems continuously move water during use, helping keep smoke cooler over longer pulls.
Common Beginners Mistakes
Assuming More Percolators Are Always Better
More filtration does not always improve the experience. Additional chambers can increase cleaning requirements and draw resistance.
Ignoring Airflow
Many people focus entirely on filtration, but airflow has a huge impact on daily usability and comfort.
Buying Overly Complex Glass Too Early
Simpler designs are often easier to maintain and enjoy long term.
Neglecting Cleaning
A dirty percolator quickly loses effectiveness. Regular cleaning helps maintain airflow, filtration and flavour.
How to Clean a Percolator Bong
Percolators work best when they're clean.
Over time, residue can block diffusion holes and reduce airflow. More complex percs usually require more maintenance than simpler designs.
Basic Cleaning Tips
• Change bong water regularly
• Rinse after use where possible
• Use a dedicated bong cleaner
• Allow cleaning solution to reach all chambers
• Avoid letting residue build up too heavily
For deeper cleaning, specialist bong cleaning products and isopropyl-based cleaners can help remove stubborn residue from complex percolators.
Jimmy Green's Tips & Takeaways
• More percolators do not automatically mean a better bong.
• Airflow matters just as much as filtration.
• Matrix percs remain one of the best all-round designs.
• Halo percs help reduce excessive bubble build-up while maintaining airflow.
• Easy cleaning often matters more than maximum diffusion.
• Choose a bong that suits how you actually use it.
