Distinct fibers imbue each media with unique dust filtration properties. Further treatments can enhance filtration efficiency and performance, extending the media's life cycle, improving dust cake release, reducing valve pulsing, maintaining consistent airflow, lowering differential pressure, and decreasing downtime and maintenance.
