If you love your bong but hate how quickly the water gets dirty, an ash catcher might be the single most practical upgrade you can add. This small piece of glass hardware sits between your bowl and your bong, and it does exactly what the name suggests. In this educational guide from Ziggy's Miami's ash catchers collection, we explain what an ash catcher does, how to match one to your setup, and how to choose the right style for adults 21 and older.
What an Ash Catcher Does
An ash catcher is an attachment that connects to the joint of your bong and holds your bowl. As air passes through it, the ash catcher captures loose ash and debris before they reach the main chamber. Many ash catchers also contain their own percolator, which means the air passes through an extra stage of water filtration on its way into the bong. The two practical benefits are simple: a cleaner main chamber and an added layer of filtration. Because most of the residue collects in the ash catcher instead of your bong, your bong stays cleaner far longer between deep cleans.
Matching Joint Size and Angle
Fitment is where most first-time buyers go wrong, so measure carefully. Two things must line up: joint size and joint gender, plus the angle of your bong's joint.
- Joint size: Bongs typically use 10mm, 14mm, or 18mm joints. Your ash catcher must match the size of your bong's joint.
- Joint gender: The ash catcher needs a male end to fit your bong's female joint, and a female opening on top to receive your bowl. Confirm both ends before buying.
- Joint angle: Ash catchers are made in 45 degree and 90 degree angles to match the angle of your bong's joint.
45 Degree vs 90 Degree
The angle you need depends on how your bong's joint is oriented. A 90 degree ash catcher is designed for bongs with an upright, straight-up joint, such as many beaker and straight-tube designs. A 45 degree ash catcher suits bongs with a joint that angles outward, which is common on many scientific-style pieces. Choosing the wrong angle leaves the ash catcher tilting awkwardly and can stress the joint, so always match the angle to your specific bong rather than guessing.
Perc Types to Know
Many ash catchers include a percolator that adds water filtration. Common styles include:
- Showerhead perc: A vertical tube with slits that spread air through the water. Reliable and easy to clean.
- Honeycomb perc: A flat disc with many small holes that break up airflow across the surface.
- Tree perc: Multiple arms with slits; visually striking but with more nooks to clean.
- Fixed or simple diffuser: A basic downstem-style diffuser for those who want filtration with minimal maintenance.
More elaborate percs generally add more filtration stages but also take more effort to keep clean, so weigh appearance against upkeep.
Pros and Cons
An ash catcher is a popular upgrade, but it is worth understanding the trade-offs before you buy.
- Pros: Keeps your bong's main chamber cleaner, adds a layer of water filtration, and is easy to remove and rinse on its own.
- Cons: Adds weight and height to the joint, requires correct fitment to work well, and adds one more piece to clean. On smaller or top-heavy bongs, the extra weight can affect stability.
How to Choose the Right Ash Catcher
Bring it together with a short checklist:
- Match the joint size: 10mm, 14mm, or 18mm to fit your bong.
- Confirm the gender: Male to your bong, female to your bowl.
- Match the angle: 45 degree for angled joints, 90 degree for upright joints.
- Pick a perc for your habits: Simpler percs for easy cleaning, elaborate percs for more filtration stages.
- Mind the balance: Consider your bong's size and stability before adding weight at the joint.

Cleaning Your Ash Catcher
Because an ash catcher does the dirty work, it needs regular cleaning to keep airflow smooth. Empty and rinse it after sessions, and give it a periodic soak using a standard glass-cleaning routine. The same approach you use for your bong applies here; our guide on how to clean a bong walks through a simple, effective method that works for ash catchers too. Handle glass gently, let pieces dry fully, and store the ash catcher where it will not tip or roll.
FAQ
Will an ash catcher fit any bong?
No. You need to match the joint size, the joint gender, and the joint angle to your specific bong. Measure your bong's joint before buying so the ash catcher seats correctly.
How do I know if I need a 45 or 90 degree ash catcher?
Look at your bong's joint. If it points straight up, choose a 90 degree ash catcher. If it angles outward, choose a 45 degree ash catcher so the piece sits level.
Does an ash catcher make cleaning easier?
Generally yes. Because most ash and residue collect in the ash catcher, your bong's main chamber stays cleaner longer. You do add one more piece to rinse, but it is quick and keeps your bong fresher between deep cleans.
