4" Spooky UFO Perc Glass Ash Catcher

When the clouds clear and the smoke slides through a glass UFO, you know you’ve got the right catcher.

What It Is

The 4" Spooky UFO Perc Glass Ash Catcher from the AFM Smoke collection is a compact, all‑glass accessory built to sit between your rig and water pipe. It features a 14 mm or 18 mm joint, selectable at either a 45° or 90° angle, so it fits the majority of setups without a fight.

Its standout UFO perc—an “Unidentified Filtration Object”—acts like a mini‑filter, diffusing and cooling each draw for smoother, cleaner hits. At just four inches tall, the piece is small enough to stay out of the way yet big enough to do its job, making it a solid addition to any rig from the ash catchers lineup.

Why You’ll Love It

• Clean hits: the UFO perc cools and filters smoke, delivering smoother pulls with less residue.
• Versatile fit: choose 14 mm or 18 mm joints and 45° or 90° angles, so it slots into almost any rig.
• Rugged glass: solid borosilicate construction resists thermal shock and holds up to heavy use.
• No‑frills performance: it does exactly what an ash catcher should—catch ash and filter smoke—without extra gimmicks.
• AFM compatibility: pairs perfectly with other AFM pieces, keeping your setup cohesive and reliable.

How To Use It

Attach the catcher to your rig using the appropriate joint size, set the angle that matches your pipe, and stack it above your water chamber. Light as you normally would; the UFO perc will do the filtering work. For care, rinse with isopropyl alcohol and coarse salt after each session, then let dry before re‑assembling.
