The Encore 4" Matrix Ash Catcher adds a second stage of matrix-perc diffusion while keeping ash, resin and debris out of your bong, a $34.95 upgrade that makes hits smoother and cleaning far less frequent. It comes in multiple joint sizes and angles so it fits almost any setup. Here's why it's one of the best low-cost upgrades you can make.

Matrix diffusion, cleaner glass
Inside this compact 4" can sits a matrix perc, a gridded diffuser that breaks your smoke into a fine curtain of bubbles for extra-smooth, cool hits. Just as importantly, it catches ash and resin before they reach your bong, so your main piece stays cleaner and you deep-clean it far less often. It's the classic two-in-one ash catcher benefit: smoother smoke and less maintenance.

- Three joint options: 14mm 45°, 14mm 90°, or 18mm 90°, pick the one that matches your bong.
- Compact 4" size adds filtration without piling on height.
- Bold color accents: Green, Milky Green, Red, Blue, Black or Teal.
- 4mm thick glass built for daily use.

How to pick the right fit
Match your bong's joint size and angle. If your bong has a 14mm female joint (most common), choose the 14mm option, then match the angle: a 90° catcher for a straight-up joint, a 45° for an angled one. Larger pieces use the 18mm 90°. Not sure? Our guide to a 45 vs 90 degree ash catcher walks you through it.
Frequently asked questions
What does a matrix ash catcher do?
It attaches between your bowl and bong and adds a matrix-perc chamber that diffuses smoke for smoother hits while trapping ash and resin before they reach your bong, keeping your glass cleaner for longer.
What size ash catcher do I need?
Match your bong's joint size (14mm or 18mm) and angle (45 or 90 degrees). This catcher comes in 14mm 45°, 14mm 90°, and 18mm 90° so you can fit most setups.
Does an ash catcher add drag?
A percolated catcher like this adds a little extra diffusion, and therefore a slight bit of drag, in exchange for noticeably smoother, cooler hits and a cleaner bong.
Can I choose the color?
Yes. Note your preferred color (Green, Milky Green, Red, Blue, Black or Teal) at checkout. If no preference is given, a random color is sent.
