Percolator Types Explained: Which Perc Gives You the Smoothest Hit?

Quick answer: There are eight common types of percs: showerhead, tree, honeycomb, inline, matrix, Swiss, turbine and UFO (disc). Honeycomb and matrix give the most diffusion for flower, inline and showerhead keep the most flavor on a dab rig, and one or two percs is plenty for most pieces.

A percolator is the glass structure inside a bong or dab rig that splits each pull into smaller bubbles before it reaches the neck. Every design does that job differently, with a different mix of diffusion, drag and cleaning effort. Below is every major perc type, how each one pulls, which ones suit flower and which suit concentrates, and what to look at before you buy a perc bong.

Types of Percs at a Glance

Here are all eight perc types side by side. Diffusion is how finely the perc breaks up each pull. Drag is how hard you have to pull through it. Cleaning is rated 1 (rinse and go) to 5 (plan on a long soak).

Perc type	What it looks like	Diffusion	Drag	Cleaning	Best for
Showerhead	Vertical tube that flares into a slitted bell	Medium	Low	2/5	Everything; the safe default
Tree	Center column with 4 to 16 slitted arms	High	Medium	4/5	Dedicated flower pieces
Honeycomb	Flat disc drilled with dozens of holes	Very high	Medium to high	4/5	Flower, stacked in a straight tube
Inline	Horizontal tube with slits along its length	Medium	Low	2/5	Dab rigs and recyclers
Matrix	Barrel with stacked rows of slits	Very high	Medium to high	3/5	Flower beakers and straight tubes
Swiss	Large holes through the glass wall itself	Medium	Low	1/5	Both flower and dabs
Turbine	Disc with angled slits that spins the water	Low to medium	Low	2/5	Second perc above a showerhead or inline
UFO (disc)	Wide flat dome with slits around the edge	Medium	Medium	2/5	Mid-size bongs

If you only read one line: a showerhead is the safe pick for any piece, honeycomb and matrix are the high-diffusion flower percs, and inline is the dab rig perc.

What Percolators Actually Do

Every water pipe already has one diffuser: the downstem, the tube that runs from the bowl joint into the water. A percolator is any extra glass structure that forces air through water again, or through finer openings, before it reaches the neck.

Water does three jobs in a pipe. It cools the pull, it catches heavier particles, and it breaks air into bubbles. Smaller bubbles mean more surface touching the water, so a perc that makes smaller or more numerous bubbles gives more cooling and filtering per pull.

The trade is drag. Every slit, hole and chamber adds resistance, and every extra pass through water cools the vapor further. On a flower bong that extra cooling is welcome. On a dab rig it strips terpene flavor, which is why the best dab rig percs are simple ones.

Water level matters as much as perc type. Too little water and the perc slits sit dry; too much and you get splash and heavy drag. Our water level guide for every percolator covers the fill line for each design.

Do Bong Percs Actually Do Anything?

Yes. A perc measurably changes how a piece pulls. What it does not do is make a badly built piece good, and past two percs the gains get small while the drag and cleaning keep growing.

What a perc does change:

• Bubble size. A plain open-ended downstem releases a few big bubbles. A showerhead or honeycomb breaks the same pull into many small ones, so more of it touches water.
• Temperature at the mouthpiece. More water contact means a cooler pull. This is the main thing people mean by "smoother."
• Splash and noise. A well-designed perc settles the water into a steady bubble pattern instead of a gurgle that throws water up the neck. Swiss and turbine percs are built for this.
• Flavor on dabs. Heavy diffusion cools concentrate vapor so much that terpenes drop out. This is the one area where more perc is worse.

What a perc does not change is the rest of the setup. Water level, bowl or banger size and the glass quality still decide most of how a piece pulls, so treat the perc as a comfort and flavor feature of the glass.

Where percs disappoint is in cheap pieces, where slits are cut unevenly so most of the air exits through one or two openings. A clean, even bubble pattern across the whole perc is the sign of a well-made one.

Showerhead Perc

The workhorse. It is the most common percolator in bongs and dab rigs at every price point, and for good reason.

A showerhead perc is a vertical tube that flares at the bottom into a rounded bell with slits or holes around the base. Air travels down the tube, exits through those slits and rises as a ring of small bubbles.

How it pulls: Even and consistent. Not the most diffusion you can get, but plenty for daily use.

Pros: Easy to clean. Low drag. Durable, with no thin arms to snap.

Cons: Moderate diffusion. It will not match a stacked honeycomb or a matrix for cooling.

Best for: Nearly everything. A showerhead suits a flower beaker and is light enough for a concentrate rig. If you are unsure which perc to get, get a showerhead.

Our take: The perc with the fewest downsides. It cleans quickly and rarely gives trouble, which is why it shows up in so many first pieces.

Tree Perc

Tree percs look like they sound: a central column with several arms branching off it, each arm slitted at the bottom. The arms hang down into the water and air passes through every arm at once.

Arm count varies: four, eight, twelve, even sixteen. More arms means more diffusion.

How it pulls: Heavy diffusion. Many arms release a lot of small bubbles at the same time, and a well-made twelve-arm tree pulls very gently.

Pros: Strong diffusion. Looks impressive in the glass. Each arm carries only part of the airflow, so drag stays reasonable in a well-made piece.

Cons: The arms are fragile. Each one is a thin glass tube held at one end, and they snap if the piece is knocked or shaken too hard during cleaning. Resin collects inside the narrow arms where solvent struggles to reach. Cheap tree percs often have uneven arms that bubble from one side only.

Best for: Dedicated flower pieces where you want maximum cooling and are willing to handle the glass carefully. Too much diffusion for a dab rig.

Our take: Beautiful, effective and high maintenance. A good choice if you clean often and do not travel with the piece.

Honeycomb Perc

A flat glass disc with dozens of small holes, mounted horizontally inside the tube. Air has to pass through those holes to keep rising, which creates a very large number of tiny bubbles.

It is one of the most effective designs for its size, and you can stack two or three discs in one straight tube, each adding another layer of diffusion.

How it pulls: Very gentle. A double or triple honeycomb gives about as much cooling as any perc on this list.

Pros: Outstanding diffusion. Low profile. Stacks well. Sturdier than tree arms because it is a solid disc fused to the wall.

Cons: It clogs. Honeycomb holes gum up with resin faster than almost any other perc, and drag climbs quickly once they do. Too much diffusion for concentrates.

Best for: Flower straight tubes and beakers, for someone who will clean on a schedule.

Our take: Probably the best pure-diffusion perc, with one condition: keep it clean. A clogged honeycomb pulls harder than a plain downstem and diffuses less.

Inline Perc

A horizontal tube with slits along its length, mounted sideways at the base of the piece. Air enters one end, exits through the slits along the whole tube and spreads across the base chamber.

Inline percs are common in recycler rigs, where they act as the first diffusion point before water cycles through the recycler loop.

How it pulls: Clean and balanced. The horizontal layout spreads bubbles across a wide area without much drag, so the pull feels light.

Pros: Low drag. Works well as the base perc in multi-chamber pieces. Resin settles toward the low points where it is easy to flush. Consistent from pull to pull.

Cons: Needs a wider base, so pieces with inlines tend to have a larger footprint. Less dramatic to look at than a tree or honeycomb.

Best for: Dab rigs, and recyclers in particular. An inline paired with a recycler loop is one of the best setups for concentrates because it smooths the pull with little flavor loss. It also works as the foundation perc in taller flower bongs. If you want the recycler side explained, see how a recycler dab rig works.

Our take: Underrated. Inlines are not flashy, but they perform consistently and are one of the few designs that suits both flower and concentrates.

Matrix Perc

A cylindrical barrel with several rows of slits or holes stacked vertically, often with a domed cap. Think of it as a more intense showerhead: the barrel shape and stacked rows give a lot of diffusion from a compact unit.

How it pulls: Very gentle for flower. Among the coolest-pulling designs here.

Pros: Heavy diffusion in a compact design. Sturdier than tree arms. Looks great in a clear beaker.

Cons: Lots of internal surface area to clean. More drag than a showerhead or inline. Overkill for concentrates.

Best for: Flower beakers and straight tubes where a cool, gentle pull is the priority. A small matrix also appears in compact rigs, where it is kept short to limit drag.

Our take: Impressive engineering that packs a lot of diffusion into a small space. For a full-size piece, treat it as a flower perc.

Swiss Perc

Named because the glass looks like Swiss cheese: large holes go straight through the body of the chamber, and water and air move around them as they rise.

It works differently from the other percs. Instead of forcing air through slits, a Swiss perc disrupts the flow path, and the holes create a swirling mix of air and water.

How it pulls: Gentle with a swirling character. Drag is low for the amount of cooling you get.

Pros: Distinctive look. Low drag for its diffusion. The big holes rarely clog. Splash is minimal because the holes redirect water away from the mouthpiece.

Cons: Takes up space. Less total diffusion than a honeycomb or matrix. Mostly found in pricier pieces because it is harder to make.

Best for: Anyone who wants one piece for both flower and dabs. The moderate diffusion keeps enough flavor for concentrates while still cooling a flower pull.

Our take: The low-splash design alone makes it worth a look. It is a mid-level diffusion perc, though, so if maximum cooling is the goal, go honeycomb.

Turbine (Cyclone) Perc

A flat disc with angled slits that spin the water as air passes through, producing a visible vortex in the chamber.

Turbines are as much about looks as function. The spinning water adds some diffusion and cooling, but the real draw is watching the cyclone form.

How it pulls: Moderate. Less thorough than a honeycomb or tree. Low drag and clean airflow.

Pros: Striking to watch. Low drag. Easy to clean. Doubles as a splash guard because the spinning water stays against the walls.

Cons: On its own it adds little diffusion. Best paired with another perc below it.

Best for: A second perc above a showerhead or inline. Gentle enough for concentrates.

Our take: Fun and effective as a splash guard. Do not buy a piece for the turbine alone; check that real diffusion is happening below it.

UFO (Disc) Perc

A wide, flat dome shaped like a flying saucer, with slits or holes around its edge. Same idea as a showerhead, but wider and flatter, so the bubbles spread over a broader plane.

How it pulls: Close to a showerhead, slightly gentler. Moderate drag.

Pros: Good diffusion and an even bubble pattern. Decent durability.

Cons: More splash than narrower percs. Not much better than a well-made showerhead in practice.

Best for: A small step up from a basic showerhead without the drag of a honeycomb or matrix. Fine for flower and for light dab use.

Our take: Very close to a showerhead in performance. If you are choosing between a UFO perc piece and a showerhead piece, pick the one with the better glass and joint quality.

Percs for Concentrates vs. Percs for Flower

This is the part most guides get wrong. The best perc for a flower bong is not the best perc for a dab rig. The two rankings are close to opposite.

Flower Pieces Want More Diffusion

A flower bowl produces a hot pull with plenty of particles in it, so more water contact helps. Honeycomb, matrix, tree and two-perc setups all make sense here, and flavor loss is less of a concern than on a rig.

Dab Rigs Want Less Diffusion

Concentrates are vaporized on a hot banger, and that vapor carries terpenes, the flavor compounds that drop out with extra cooling and water contact. Every additional perc removes more flavor.

The ideal concentrate setup is a small rig with a single simple perc: an inline, a small showerhead or a plain downstem. Enough to smooth the pull without stripping the flavor. Running dabs through a triple honeycomb bong gives a very cool pull with very little taste.

Perc Rankings by Use

For flower, most to least diffusion:

1. Honeycomb (stacked double or triple)
2. Matrix
3. Tree (12 or more arms)
4. Showerhead
5. Swiss
6. Inline
7. Turbine
8. UFO (disc)

For concentrates, best to worst:

1. Inline (especially in recyclers)
2. Showerhead (small, single)
3. Swiss
4. UFO (disc)
5. Turbine
6. Tree (small, 4-arm)
7. Matrix
8. Honeycomb

The two lists are nearly reversed, and that is the whole point: match the perc to what goes in the bowl or on the banger.

Triple Perc Bongs: How Many Percs Is Too Many?

A triple perc bong stacks three percolators in sequence, usually a base perc (showerhead, inline or matrix), a second perc in the tube (often a honeycomb or tree) and a turbine or splash guard on top. More percs do mean more diffusion. They also mean more of everything else.

Drag goes up. Each perc adds resistance. A triple perc piece takes noticeably more effort to clear than a single-perc piece, and for many people that extra effort makes it less pleasant, not more.

Flavor goes down. Even on a flower piece there is a point where extra cooling stops helping.

Cleaning multiplies. One perc is easy. Two is manageable. Three different designs in one tube can mean a long session with isopropyl and salt every time, and if you skip it, a clogged triple perc pulls worse than a plain $30 beaker.

Breakage risk goes up. More internal glass means more joints that can crack. Tree arms snap and honeycomb discs crack if the piece takes a knock.

Our recommendation: One or two percs is the sweet spot. A showerhead under a turbine, a honeycomb with a splash guard, or an inline in a recycler all give a smooth pull without the downsides. Three percs is the practical maximum, and only for a dedicated flower piece you will clean often.

A cheaper way to add a stage is an ash catcher. A 5" Clear Showerhead Ash Catcher ($29.99) adds a second showerhead perc to a flower bong and keeps the main chamber cleaner, and you can take it off when you want the lighter pull back.

Best Perc Bongs and Rigs by Perc Type

If you already know which perc you want, here is where each one shows up in pieces we stock right now. Prices are current as of this update.

Showerhead

For a flower beaker, the 14" Encore Showerhead Beaker ($55.99) is the plain, easy-to-clean starting point. For dabs, the 5" Clear Classic Showerhead Rig ($53.99) keeps the chamber small so flavor holds up.

Honeycomb

The 9" Encore Color Accent Honeycomb Straight ($52.99) is a straight tube built around a honeycomb disc, the classic flower layout.

Matrix

The 16" Clear Matrix Thick Base Beaker ($71.21) is a full-size flower beaker with a matrix perc. On the rig side, the 9" Encore Color Lip/Foot Matrix Rig ($44.99) keeps the matrix small enough for concentrates.

Inline and Recycler

The 10" Vac Stack Horn Inline Rig ($56.49) is built around an inline perc. For an inline-style base feeding a recycler loop, the 7.5" Encore Infinity Loop Recycler ($63.99) and the 9.5" Pillar Recycler ($74.99) are both in stock. More options sit in our recycler collection.

Cone and Other Rig Percs

The 8" Cone Perc Rig ($47.99) uses a cone-shaped perc, a close relative of the showerhead with slits around a tapered base. It is a simple, low-drag rig perc.

Whatever you pick, check four things before buying: the slits are cut evenly all the way around, the perc is fused cleanly to the tube with no thin spots, the joint size matches your bowls and bangers, and the base is wide enough to sit steady on a table.

Cleaning Percolators: Honest Difficulty Ratings

Ratings run from 1 ("rinse and go") to 5 ("plan on a long soak").

Perc Type	Cleaning Difficulty	Notes
Swiss	1/5	Big holes flush clean with a quick rinse
Showerhead	2/5	Open design, iso and salt clear it fast
Inline	2/5	Horizontal tube is easy to flush
UFO (disc)	2/5	Wide and accessible, no tight spots
Turbine	2/5	Flat disc, easy to reach, little buildup
Matrix	3/5	Lots of internal surface area, moderate effort
Tree	4/5	Narrow arms trap resin and are slow to clear
Honeycomb	4/5	Tiny holes clog fast and need frequent cleaning

The general rule: the better a perc diffuses, the harder it is to clean. The tiny holes and narrow passages that make lots of small bubbles are the same features that trap resin.

Tip: Clean before it gets bad. A quick iso rinse every few sessions prevents the buildup that needs a soak. For a full method, see our deep-clean guide for resin buildup.

Frequently Asked Questions

How many types of percs are there?

Eight are common: showerhead, tree, honeycomb, inline, matrix, Swiss, turbine and UFO (disc). You will also see variants such as cone percs, coil and fritted-disc percs, and recyclers, which are a chamber design rather than a perc but are often listed alongside them.

What is the smoothest percolator type for bongs?

For flower, a stacked honeycomb is hard to beat, with matrix a close second that is a little easier to clean. "Smoothest" and "best" are not always the same, though. On a dab rig the highest-diffusion percs are the worst choice because they strip the flavor.

Is a recycler better than a percolator?

They do different jobs. A percolator diffuses air through water; a recycler loops the water itself between chambers, which cools the pull and prevents splash without stacking more percs. Many recyclers include a perc at the base. For dabs, a recycler with an inline perc is one of the best setups; for flower, a perc bong is usually the better fit.

Can you dab through a bong with multiple percolators?

You can, but the result is a cool pull with little flavor. Multi-perc bongs are built for flower. For concentrates, a dedicated dab rig with one simple perc works better. If you want one piece for both, choose a medium-size piece with a showerhead or inline perc and run a lower water level when dabbing.

How often should you clean a percolator?

It depends on the perc and how often the piece is used. Swiss and inline percs can go a week or two with light use. Honeycomb and tree percs need cleaning every few sessions with daily use. The simple test: if the pull gets harder, the perc is clogging. Use 91% or stronger isopropyl and coarse salt, plug the openings and shake. For stubborn buildup, soak in iso for 30 minutes first, then rinse well with warm water.

The Bottom Line

Percolators matter, but they are not magic. The right perc matches what you use the piece for, fits your cleaning habits and does not add so much drag that every pull feels like work.

Three things to remember: a showerhead is the safest all-around choice, dab rigs need less percolation rather than more, and every perc you add is one more you have to clean.

Pick one or two good percs, keep them clean, and the glass will do the rest.
