Choosing Between an Ash Catcher and a Dry Catcher: A Quick Guide (2026)

Most bong owners buy their piece, love it for a month, then spend the next six months cleaning out resin and ash. That's exactly the problem ash catchers and dry catchers solve, and if you're running a smoke shop without a solid selection of both, you're leaving easy upsell money on the table every single day.

This guide covers everything: how each type works, which filtration style delivers smoother 
hits, how to match joint angles and sizes without guessing, what actually moves off retail 
shelves, and which wholesale ratio makes sense for most stores. Whether you're restocking 
or building out your accessory wall for the first time, here's everything you need to order right.

What Is an Ash Catcher?

An ash catcher connects between your bong's joint and your bowl. Fill it with just enough water to cover the percolator, roughly a quarter inch, and it works as a pre-filter. Ash, resin, and fine particulates get intercepted before they ever reach your bong's main water chamber.

The result is that your bong stays clean for weeks instead of days. Most ash catchers include a built-in percolator, tree percs and honeycomb percs are the most common styles, so smoke gets an extra pass through water before it reaches the user. The hit comes out noticeably cooler, smoother, and less harsh than running the same bong bare.

The IC Glass 14mm 90° ash catcher is one of the strongest sellers for standard beaker bongs. The fit is tight, the diffused downstem breaks up smoke efficiently, and the 90° angle keeps it sitting flat rather than tipping the piece forward. If a customer has a beaker bong and hasn't tried an ash catcher yet, this is the one to show them first.

One thing to flag for customers: ash catchers add a small amount of drag to the pull. Most people stop noticing it after one or two sessions. Customers who are used to a completely open draw sometimes mention it upfront, worth mentioning at the point of sale, so it doesn't become a return.

Best percolator styles for ash catchers

• Honeycomb perc — smooth diffusion, minimal drag, easy to clean. Best all-around choice.
• Tree perc — excellent filtration, slightly more drag, visually impressive in-store display.
• Showerhead perc — consistent diffusion, popular for mid-range price points.
• Diffused downstem — entry-level option, low drag, great for budget-conscious buyers.

What Is a Dry Catcher? (Waterless Style)

A dry catcher does exactly what the name says: it catches ash and debris with no water involved. Same attachment method (between the joint and the bowl), but you leave it completely dry.

The advantage is obvious: no water means no spills, no water changes, and almost zero maintenance. Take it off, tap the debris out, rinse it under the tap every few sessions. Done in under two minutes. According to glass filtration testing, a well-designed dry catcher can intercept approximately 85% of ash particles before they reach the bong, not as thorough as a wet catcher, but significant for bong longevity.

The trade-off is that you get no extra filtration or cooling. The debris gets caught, but the smoke passes through unchanged. Your bong stays clean, but the hit itself is the same as running the bong without any attachment.

Dry catchers are a strong fit for customers who already have heavy filtration built into their bongs, multi-perc setups, ice catchers, or both, and just want to protect the piece. They also move reliably to concentrate users, since there's no water to manage.

Ash Catcher vs. Dry Catcher: Side-by-Side Comparison

Joint Angle: 45° vs. 90° — Get This Right Before You Order

This is the single most common ordering mistake. The wrong angle means the catcher sits crooked, throws off the balance of the piece, and turns a great upsell into a return. Check bong joint angle before anything else.

According to Milkyway Glass, the rule is simple:

·        45° ash catcher — designed for straight-tube bongs. Holds the bowl level to the ground when the bong is sitting upright on a table. If the bowl already points away from the user at roughly a 45° angle, this is the right choice.

·        90° ash catcher — designed for beaker bongs. The bowl points straight up from the catcher when the bong is in its natural resting position. Most beaker bongs need a 90°.

Quick visual check: if the bong's bowl currently points up (like a cup), it's a 90° joint. If it points out at an angle (like a ramp), it's a 45°. If a customer isn't sure, have them bring the bong, or just ask if it's a beaker or a straight tube. Beakers are almost always 90°.

Joint Size: 14mm vs. 18mm

The two standard joint sizes are 14mm and 18mm. A 14mm joint is about the diameter of a ballpoint pen cap. An 18mm joint is closer to a standard felt-tip marker. Both the bowl and the ash catcher need to match the bong's joint exactly — mismatched sizes cause air leaks and cracked glass over time.

If a customer doesn't know their joint size:

1. Have them bring the bong in
2. Try a 14mm bowl in the joint — if it drops through, it's 18mm
3. If they're ordering online, most modern beaker bongs 10" and above use 18mm; compact bongs typically use 14mm

Get Glass carries all configurations: ash catchers and 18mm ash catchers in both 45° and 90° angles. You can mix and match within a case on wholesale orders.

Can You Stack a Dry and Wet Ash Catcher Together?

Yes, and some experienced users do exactly this. The dry catcher attaches to the bowl first to intercept the heaviest debris, then the wet catcher adds water filtration before smoke enters the bong. The result is the cleanest possible water and the smoothest possible hit.

However, this setup is only practical on large bongs (14 inches and up) with substantial chamber volume. Stacking two ash catchers creates significant drag and adds real weight to the joint connection. It's overkill for most casual users, but worth knowing for customers with premium setups who ask.

 How to Clean an Ash Catcher

Total cleaning time: 5–7 minutes for a wet catcher, under 2 minutes for a dry catcher. This difference is one of the most persuasive selling points for dry catchers at the counter.

What to Stock: Retail Ratios That Actually Work

For most smoke shops, a 3:1 ratio of ash catchers to dry catchers hits the right balance. Flower smokers, still the majority of walk-in customers, benefit more from the extra filtration and are more likely to notice and appreciate the difference. The upsell conversation is easy: point at the ash catcher on the wall, explain the benefit in 30 seconds, done.

Dry catchers move faster in shops that see strong concentrate sales, or in markets where customers already own high-end, well-filtered glass. They're more of a "customer knows what they want" purchase, lower friction, higher velocity in the right shop.

Recommended starting order: 18x ash catchers (split 14mm/18mm, split 45°/90°) + 6x dry catchers (same size/angle split). Adjust based on your bong sales mix. If you're not sure, reach out — we can pull your order history and suggest a ratio based on what bong sizes you're already moving.

Frequently Asked Questions

What is the difference between a wet and dry ash catcher?

A wet (water) ash catcher uses water and a percolator to filter and cool smoke before it enters your bong, giving you smoother, cooler hits in addition to catching debris. A dry ash catcher catches the same ash and resin but uses no water, it doesn't change the hit quality at all, but it's much easier to clean and maintain. Both attach between your bowl and your bong's joint.

Do ash catchers fit all bongs?

No, you need to match both the joint size (14mm or 18mm) and the joint angle (45° or 90°) to your bong. Most beaker bongs use a 90° joint; most straight-tube bongs use a 45° joint. Getting the wrong angle means the piece will sit crooked or tip over. Always confirm size and angle before purchasing.

Does an ash catcher make hits harsher or smoother?

A wet ash catcher makes hits noticeably smoother and cooler because it adds a second water filtration stage. A dry ash catcher doesn't change hit quality, it simply keeps debris out of your bong water. Neither type makes hits harsher when properly used, though overfilling a wet catcher with too much water can increase drag and cause splashback.

How much water do I put in an ash catcher?

Fill just enough to cover the percolator slits, approximately ¼ inch (6mm) above the bottom of the perc. Too little water and the perc won't diffuse smoke properly. Too much water increases drag, causes splashback, and can push water back into your bowl. Less is more.

How do I clean an ash catcher?

For wet ash catchers: empty the water after each use, then do a weekly soak with 91%+ isopropyl alcohol and coarse salt, shake for 60 seconds and rinse. For dry catchers: tap out debris after each session and rinse every few uses. Total cleaning time is 2–7 minutes depending on type.

Can I use an ash catcher with a dab rig?

You can use a dry ash catcher with a dab rig if the joint size and angle match. Wet ash catchers are generally not recommended for concentrates — the extra water stage dilutes vapor and reduces flavor significantly. Most concentrate users who want bong protection go with a dry catcher or a simple reclaim catcher instead.

What's the difference between a 45° and 90° ash catcher?

The angle refers to how the catcher sits relative to your bong. A 45° ash catcher holds the bowl at a diagonal angle and is designed for straight-tube bongs. A 90° ash catcher holds the bowl pointing straight up and is designed for beaker bongs. Using the wrong angle means your bowl will sit at an awkward tilt, making it harder to load and light.

Are ash catchers worth it for wholesale stocking?

Yes,  ash catchers are one of the easiest upsells in a smoke shop. A customer buying a $40 beaker bong is a natural target for a $20–$30 ash catcher add-on at the counter. Margins are strong, the pitch is quick, and customers who try one almost always repurchase. Most retailers find ash catchers among their top-5 accessory sellers within a month of stocking them properly.

What sizes does Get Glass Distribution carry?

We carry ash catchers and dry catchers in 14mm and 18mm joint sizes at both 45° and 90° angles. You can mix and match sizes and angles within a wholesale case order. Browse our full ash catcher inventory here or contact us for help building the right order for your store.

The Bottom Line

Ash catchers and dry catchers solve the same core problem, keeping your bong clean, but they do it differently and for different customers. Wet ash catchers are for smokers who want smoother hits and don't mind a little maintenance. Dry catchers are for smokers who want zero hassle and already have a well-filtered setup.

Stock both. Lead with ash catchers for flower customers, lean on dry catchers for concentrate users and the low-maintenance crowd. Get the joint angles and sizes right, and this becomes one of the easiest accessory categories in your store.
