The Atmos RX Dry ceramic filter allows for a smooth airflow and filtration. A connection between the ceramic heating chamber and the rubber mouthpiece.
The ceramic filter is an absorbent porous material, the best way to clean it is by using a paper clip or something similar, to poke the holes to ensure proper airflow. The filter is like tires on a car, over time they will need to be changed. But no worries, Lighter USA has got you covered.
