Understanding Ash Catchers
What Size Ash Catcher Do I Need?
The right size depends on your bong’s joint size and angle. Most bongs use 14mm or 18mm joints, while mini rigs may use 10mm. Always match the joint size and angle (45° for beakers, 90° for straight tubes) so your ash catcher sits correctly without tipping or spilling.
Common Joint Sizes (10mm, 14mm, 18mm)
The joint size is the connection point where your bong, ash catcher, and bowl piece fit together.
10mm – The smallest option, usually found on mini bongs or rigs. Lightweight and discreet, but more fragile.
14mm – The most common size, offering a good balance between airflow and compatibility with accessories.
18mm – Larger joints designed for bigger bongs. They allow more airflow and sturdiness but add weight.
👉 Always match the ash catcher joint size with your bong’s joint size to ensure a secure fit.
Angles (45° vs 90°) and When to Use Them
Ash catchers are designed with joint angles to align with your bong’s downstem.
45° Joint – Best for bongs with angled downstems (common in beaker bongs). Keeps the ash catcher upright and stable.
90° Joint – Suited for straight-tube bongs or pieces with vertical joints. Helps the ash catcher sit flush without tilting.
👉 If the angle doesn’t match, your ash catcher may sit awkwardly, spill water, or even tip your bong.

Are Ash Catchers Worth It?
Yes — ash catchers are absolutely worth it if you want to keep your bong cleaner, enjoy smoother hits, and extend the life of your glass. They catch debris before it reaches your piece, saving time on cleaning and protecting your investment. Even cheap ash catchers can make a big difference in daily use.

What are the different types of ash catchers?
Dry Ash Catcher
A dry catcher doesn’t use water — it simply traps ash and debris before they reach your bong. These are lightweight, super easy to clean, and ideal if you want protection without extra drag or water levels to manage.
Percolator Ash Catcher
Percolator ash catchers include built-in diffusion systems like tree, honeycomb, or showerhead percs. They filter and cool the smoke while catching debris, giving you smoother, less harsh hits. Perfect for smokers who value extra filtration.
Reclaim Catcher
Designed mainly for dab rigs, reclaim catchers collect leftover concentrate (reclaim) instead of letting it build up inside your rig. This not only keeps your glass cleaner but also lets you reuse reclaim if desired — making it a money-saving accessory for concentrate users.
Multi-Chamber Ash Catcher
A multi-chamber catcher adds multiple layers of water filtration. Each chamber can hold its own perc or diffusion system, giving maximum cooling and smoother smoke. The trade-off is more weight and tougher cleaning, but the payoff is unmatched performance.

How to clean an ash catcher
Empty and disassemble your ash catcher, then rinse everything with warm (not boiling) water. Fill the body about ⅓ with 90% isopropyl alcohol and add a tablespoon of coarse salt, cap the openings, and shake for 60–90 seconds (repeat or soak 10–20 minutes for heavy buildup). Clean the bowl/downstem in a zip bag with the same ISO + salt, scrub tight spots with cotton swabs or pipe cleaners, then rinse all parts until there’s zero alcohol smell and air-dry before reassembling with fresh water.
Step-by-step (10–20 minutes)
What you’ll need:
91–99% isopropyl alcohol (ISO), coarse salt (or uncooked rice), rubber stoppers/plugs (or your fingers + paper towels), warm water, cotton swabs/pipe cleaners, a zip bag for small parts.
Disassemble.
Empty the water. Remove the bowl and downstem.Warm rinse.
Rinse the body and parts with warm (not boiling) water to loosen gunk.Load the cleaner.
Pour ISO into the bong (about ⅓ full). Add 1–2 tbsp coarse salt (the scrubber).Seal the openings.
Cap the mouthpiece and joint with stoppers or paper towels.Shake—gently but thoroughly.
Shake 60–90 seconds, rest, then repeat. Support any percs while shaking.Soak (optional but effective).
Let it sit 10–30 minutes for heavy buildup.Clean the small parts.
In a zip bag, add ISO + salt, drop in the bowl/downstem, shake, then soak 10–15 minutes. Use pipe cleaners to finish the inside of the stem.Detailing.
Use cotton swabs on tight spots (joint, percs, lip).Rinse to neutral.
Rinse everything with warm water until there’s zero alcohol smell and no salt left. A tiny drop of dish soap is fine—rinse fully after.Dry + reassemble.
Air-dry upside down or towel the joints. Add fresh water and you’re good.
Material notes:
Glass/Ceramic: Safe with ISO + salt. Avoid sudden temp changes (no boiling).
Silicone: Use warm water + dish soap (or a denture tablet). Skip ISO/acetone—they can degrade silicone.
Acrylic: Use warm water + mild dish soap only; avoid ISO and coarse abrasives that can cloud/scratch.
Quick upkeep tips:
Change water daily, quick-rinse after sessions, use a screen or ash catcher to keep resin down, and store with travel plugs to prevent stink.
how much water are you supposed to put in a ash catcher vs a dry catcher
Here’s the quick rule:
Wet ash catcher (with perc): Add just enough water to cover the perc’s slits/holes by ~3–5 mm (⅛–¼”). More than that = extra drag and splash.
Dry ash catcher: No water. It’s meant to trap debris only. (A small amount is optional to tame dust, but not necessary.)
Easy fill method (works every time)
Detach the ash catcher.
Fill slowly until the perc slits are barely submerged.
Test draw (no flame): you want a lively bubble with minimal pull.
Attach to bong and take a light pull—if you feel water creep toward the joint, pour a little out.
Frequently Asked Questions
What exactly is an ash catcher?
An ash catcher is a bong attachment that traps ash, resin, and debris before they enter your main chamber. By acting as a pre-filter, it keeps your glass cleaner, makes maintenance easier, and improves the smoothness of each hit.
Can an ash catcher be used on any bong?
Not always — ash catchers must match your bong’s joint size (10mm, 14mm, 18mm) and joint angle (45° or 90°). As long as the measurements line up, most bongs can use an ash catcher for added filtration and protection.
Does Amazon sell ash catchers?
Yes, Amazon lists ash catchers, but specialty online smoke shops often carry a wider selection of premium glass ash catchers with unique percolators, better build quality, and more sizing options.
Are you supposed to put water in a bong ash catcher?
Most ash catchers are designed to hold a small amount of water, which adds an extra layer of filtration and cooling. However, dry ash catchers don’t require water — they simply block ash and debris. Always follow the design of your specific piece.
Do ash catchers really work?
Yes — ash catchers keep your bong cleaner for longer, reduce harshness, and improve smoke quality. They’re especially useful if you smoke often and want to save time scrubbing resin from your main piece.
Do ash catchers change the taste?
Ash catchers can actually improve flavor by filtering out harsh debris and cooling the smoke. However, if not cleaned regularly, they may negatively affect taste due to resin build-up.
How often should I empty my ash catcher?
For best performance, empty after every session and rinse daily. Letting ash and dirty water sit too long can clog airflow and affect taste.
What’s the difference between a wet and dry ash catcher?
Wet ash catchers hold a small amount of water to filter and cool smoke.
Dry ash catchers don’t use water — they strictly catch ash and debris.
Both reduce mess, but wet versions provide smoother hits, while dry catchers are easier to clean.
