Each type of fiber imbues the filter media with distinct dust filtration properties. Advanced treatments can further elevate the media's efficiency and performance, leading to longer lifespans, improved dust cake release, reduced valve pulsing, more consistent airflow, and minimized differential pressure, downtime, and maintenance.
