The K&N DryCharger is a silicone-treated polyester pre-filter wrap made to cover K&N air filters or personal watercraft flame arrestors, extending filter life while allowing high airflow. Uniform micron-sized openings preserve breathing capacity, while the water-repellent treatment limits water ingestion; treatment typically lasts one to two years under normal use.
