What does “Diffuser” mean?An extra piece to a bong that enhances airflow and provides a smoother, cleaner experience. They force the smoke to pass through the water in the bong to clear it of any burnt plant matter before reaching your lungs. Diffusers can be as simple as a straight tube, or they can be extremely complex with multiple additions, shapes, and holes to provide extra filtering. Unfortunately, the more complex the diffuser, the more difficult it is to clean.
Example usage for Diffuser
“I love the smooth hits I get with a complex diffuser, but I didn't realize how much it would suck to clean.”
