An ash catcher is an add-on chamber that traps ash and resin before it reaches your bong — cleaner water, smoother hits, and far less scrubbing. Below are the ash catchers we stock in 14mm and 18mm with tree, showerhead and circ percs, shipping fast from the US. Not sure which joint size you need? Our guide to bong bowl sizing covers 14mm vs 18mm fit.
How to choose an ash catcher
Three things to match before you buy:
Joint size & angle
Match your bong's joint — 14mm or 18mm — and the angle (45° or 90°) so it sits right.
Gender
The ash catcher must be the opposite gender of your bong's joint to fit. Most modern bongs take a male ash catcher.
Perc type
Tree, showerhead and circ percs each add extra filtration and cooling — more diffusion means smoother hits.
Reclaim option
Some ash catchers double as a reclaim catcher with a silicone jar — handy for concentrate users.

Frequently asked questions
What does an ash catcher do?
It's a pre-filter chamber that catches ash, resin and debris before they reach your bong, keeping the water and glass cleaner and the hit smoother. It also adds an extra stage of filtration.
What size ash catcher do I need?
Match your bong's joint size (commonly 14mm or 18mm) and pick the opposite gender so it fits. Also match the joint angle — 45° or 90°.
Does an ash catcher make hits smoother?
Yes — the extra chamber and perc add diffusion and cooling on top of your bong's, so hits are noticeably smoother, and your bong stays cleaner longer.
14mm vs 18mm ash catcher — which?
Whichever matches your bong's joint. 14mm is the most common on modern water pipes; larger beakers often use 18mm.
How do I clean an ash catcher?
Empty it after sessions and soak in isopropyl alcohol with coarse salt, then rinse — the same as cleaning a bong. Because it catches the worst of the residue, regular rinsing keeps everything tasting clean.
