AFM UFO Line: Disc Perc Bongs Built for Diffusion

The AFM UFO Line is built around a UFO style percolator, a flat disc-shaped perc with slits around its edge that break smoke into many small bubbles. That wide spread of fine bubbles is what cools and smooths each pull, so the line delivers strong filtration without choking down your draw. Each piece pairs the disc perc with a signature rounded bulge in the neck of the beaker that opens up airflow into the percs.

The result is a beaker that handles bigger hits while keeping them smooth. More air reaches the UFO disc on every pull, so you get larger draws with better filtration rather than a tight, restricted feel. Compared with a simple diffused downstem, the disc creates far more bubbles; compared with tall tree or matrix percs, it stays compact and adds less drag. It is a practical middle ground for daily use.

Why Choose a UFO Line Bong

• A disc-shaped UFO perc that spreads smoke into fine bubbles for smooth filtration.
• The signature bulged neck that opens up airflow for larger, easier hits.
• Compact percolation that filters well while staying easy to clear.
• Premium glass construction built for everyday performance.
• Simple to maintain with a regular isopropyl and salt clean.

UFO Line FAQs

What is a UFO perc?
A UFO perc is a flat, disc-shaped percolator with slits around the edge that spread smoke into many small bubbles for filtration. In the AFM UFO Line, the design pairs with a signature rounded bulge in the neck of the beaker that opens up airflow into the percs.

How does the UFO perc design work?
Smoke is pulled down into the water and through the slits in the UFO disc, which breaks it into fine bubbles that cool and filter the smoke. The rounded bulge in the neck lets more air reach the percs, so you can take larger hits with better filtration on each pull.

Is a UFO perc good for filtration?
Yes. The disc shape creates a lot of small bubbles across a wide surface, which cools and smooths the smoke well. Combined with the wider airflow from the bulged neck, the UFO Line delivers a smooth hit without choking down your draw.

How does a UFO perc compare to other percs?
Compared with simpler diffused downstems, a UFO disc creates more bubbles for smoother filtration. Compared with tall tree or matrix percs, the UFO is compact and adds less drag, so it filters well while staying easy to clear. The bulged neck design is what sets the AFM line apart.

How do I clean a UFO perc bong?
Fill with isopropyl alcohol and a little coarse salt, cover the openings, and shake gently so the solution moves through the perc slits. Let it soak if buildup is heavy, then rinse thoroughly with warm water. Cleaning the perc regularly keeps the bubbles flowing and the airflow smooth.
