Each type of fiber imparts unique dust filtration characteristics to the media. Additionally, filter media can undergo treatments to enhance filtration efficiency and performance. These improvements include longer filter media life cycles, superior dust cake release, reduced valve pulsing, consistent airflow, lower differential pressure, and minimized downtime and maintenance.
