Yes, some ash catchers hold water. Wet catchers filter and cool smoke with water, while dry catchers trap ash without altering airflow. To use a wet catcher, fill just above the perc or diffuser holes—enough to function without overfilling.
Ash catchers change how your glass performs. They cut down on mess, they shift most of the cleaning away from the main chamber, and they can make smoke taste smoother. For a small accessory, the effect on daily sessions is bigger than many people expect.
There are two styles to think about.
A dry ash catcher stays empty and works like a filter basket. Ash never reaches your bong water, airflow stays wide open, and the hit feels the same as it would without the attachment.
A wet ash catcher holds water and often uses a perc. This setup adds a layer of filtration, cools the smoke, and takes some of the bite out of a heavy rip.
Both options protect your bong, but they offer very different draws.
Every piece by Thick Ass Glass is built from thick borosilicate and refined with CAD designs so that size, angle, and function stay consistent from batch to batch. We’ve been obsessed with airflow and durability from the start, and ash catchers are no exception.
In the sections ahead, you’ll see exactly when to add water, how much to use, what benefits to expect, and how to keep a catcher in top condition.
The Real Job of an Ash Catcher
An ash catcher is more than a decorative add-on. It acts as a working barrier that changes how often you clean your glass and how smooth your sessions feel. Think of it as a first stage in the smoking process that handles debris and tar before they ever reach your bong’s water chamber.
With the right size and angle, it fits seamlessly into your setup and actually makes ownership easier.
Why Ash Catchers Exist
The first job of an ash catcher is to keep unwanted debris from entering the main chamber. By intercepting ash and resin at the joint, the water in your bong stays noticeably clearer between changes. Cleaner water translates to cleaner pulls, and that difference is obvious after just a few uses.
Because the ash catcher collects most of the buildup, your bong requires far fewer deep scrubs. Instead of breaking down the whole piece every other day, you can usually just rinse the catcher and keep going.
Don’t Overlook Fit and Function
Getting the right fit is as important as choosing the right style. Joint size comes first: most catchers are either 14mm or 18mm, and pairing the wrong size with your bong will lead to a poor seal. The angle is the next step.
Beaker bongs almost always call for a 45-degree joint, while a straight tube typically lines up with a 90-degree joint. Weight should also be part of the decision. Wet catchers carry both glass and water, which means thinner joints can become stressed over time.
If your bong has a narrow neck or delicate welds, a lighter dry catcher might be the smarter option.

Why Add Water to an Ash Catcher
Adding water to an ash catcher turns it into more than a debris trap. Instead of only blocking ash, the chamber starts to act like a smaller version of your bong, filtering smoke and softening the hit before it reaches the main piece.
That simple change affects flavor, smoothness, and how long your bong water stays clean.
Filtration Benefits
A water-filled catcher captures far finer debris than a dry chamber. Tiny flakes of ash and resin get pulled into the water and settle there instead of clouding up your bong. Because the dirtiest material never touches the main chamber, the base water stays clear longer.
Smokers who rely on daily sessions often notice that the bong looks almost unused even after several bowls, while the catcher does the dirty work. That swap in where the buildup collects is exactly what makes water catchers attractive to anyone tired of rinsing out their piece every night.
Comfort Benefits for the Smoker
Beyond filtration, water adds diffusion. Smoke hitting water is broken into smaller bubbles, which increases surface area and drops the temperature before you inhale. Cooler smoke is easier on the throat and lungs, especially when pulling bigger hits.
Many people who switch from a dry catcher to a water-filled version immediately describe the draw as smoother and more forgiving, even on dense bowls. That extra comfort often makes longer sessions easier, since the pull feels less harsh and the aftertaste stays cleaner.
Main Downsides of Using Water
While a wet ash catcher brings smoother pulls and cleaner water, there are tradeoffs worth considering. Some smokers enjoy the extra diffusion, but others find it slows the draw, stresses the joint, or throws off the balance of smaller rigs.
Knowing these drawbacks makes it easier to choose the right setup for how you smoke.
Added Resistance to Your Pull
The most immediate difference with a water-filled catcher is drag.
Each chamber that smoke passes through adds resistance, and when you stack a wet catcher on a bong that already has percs, the pull can feel heavier. Those with strong lungs this may be acceptable, but for others it feels like clearing the piece requires more effort than the hit is worth.
Wet Catchers Are Poor Fit for Some Bongs
A wet catcher can work against you if your bong already has heavy diffusion. When multiple percs are stacked together, the airflow may feel clogged instead of smooth. Pieces like tree percs, matrix percs, or double honeycomb designs already handle plenty of filtration.
Adding more water chambers in front of them can choke the draw and change the function of the bong in ways that do not match its original design. Certain base layouts such as stemline or gridline builds are also prone to splashing water up into the catcher, which quickly becomes irritating.
Stability Risks Are Increased
A dry catcher adds little more than an empty chamber, but once you add water the weight climbs. Thick glass plus a filled chamber can make smaller rigs unsteady, and top-heavy setups are easier to knock over.
Thin joints are also more likely to feel stressed under that extra load, especially if the bong is made with narrow welds. If you value balance and portability, a dry catcher may be the better call.
Finding the Right Water Level for Your Catcher
Water levels make the difference between a smooth pull and a clogged, noisy mess. The catcher is a small chamber, so even a few drops too much or too little can change the way it functions.
A simple approach works best: start with the basics, test before every session, and make small adjustments until the draw feels right.
Learn the Rule of Thumb and Stick to It
The simplest guide is to cover the perc holes or the tip of the diffuser with water and stop there. That ensures the design actually functions as intended while avoiding unnecessary drag.
Each model has slight variations, but this rule holds true across honeycomb, showerhead, and tree styles. The goal is to submerge the working part of the catcher, not to fill it like a full bong chamber.
Don’t Assume, Test It!
Glass is consistent at TAG because we engineer with CAD, yet even the best catcher benefits from a quick test pull after filling. Take a dry hit without lighting anything and listen for airflow.
If the pull feels smooth and bubbles activate evenly, the water level is correct. If it feels heavy, or if the sound resembles a clogged chug, pour a little out and try again. A thirty-second check saves the hassle of dealing with bad function in the middle of a session.
Overfill? Not the End of the World
Every smoker makes the mistake of adding too much water at some point. When that happens, excess usually drains into the bong itself. It is messy but does not harm the glass or the joint.
The fix is simple: empty the bong, wipe the joint, and refill both pieces with the correct levels. After a few rounds of trial and error, you will get used to the sweet spot for your specific catcher. Once you have it dialed in, your sessions feel more predictable, and cleaning stays easy.
How to Keep the Ash Catcher Maximally Effective?
Ash catchers take on the dirtiest part of the job, which is exactly why they need consistent upkeep. A well-maintained catcher does two things at once: it keeps your bong cleaner and it preserves the airflow that makes your pulls feel the way they should.
The process is simple if you make it part of your routine rather than letting residue pile up.
Water Must Stay Fresh
For wet catchers, the most direct way to keep performance steady is to replace the water after every use. Fresh water prevents stale flavor, reduces odor, and keeps resin from layering inside the chamber.
It also helps diffusion function as designed, since clean water bubbles more evenly than a sticky mix that has sat overnight. This habit adds only a minute to the routine but makes a noticeable difference in taste and airflow.
Don’t Let Grime Accumulate
Catching debris means resin will build faster in this piece than in your main bong. If you run a wet catcher, give it a quick rinse after each session and follow up with a deeper clean using isopropyl alcohol once resin begins to cling.
For dry catchers, a simple rinse is usually enough, since there is no water line to stain.
Regular upkeep prevents blockages in the perc and extends the lifespan of the joint. When glass is left dirty for too long, it requires harsher cleaning methods and is more likely to weaken at the welds.
Care Tips for Ash Catchers
Beyond water changes and cleaning, a few habits keep your catcher in peak condition:
-
Keep the joint dry when not in use to prevent sticking.
-
Remove the catcher during transport so the joint on the bong does not take unnecessary stress.
- Store the catcher upright to protect percs and avoid accidental chips.
Water Protects Your Bong, and Your Lungs
An ash catcher changes the rhythm of a session by taking the worst of the ash and resin before it ever touches your bong. Filling it with water adds another layer of defense, cooling smoke and filtering particles, while leaving it dry keeps airflow wide open.
Every catcher in the Thick Ass Glass collection is engineered with reinforced joints, thick borosilicate, and precision placement so the function matches the design.
