The choice of fibers imbues each filter media with unique dust filtration properties. Moreover, filter media can undergo specialized treatments to enhance their filtration efficiency and overall performance. Such treatments may include extending the filter media's life cycle, improving dust cake release, decreasing valve pulsing, maintaining consistent airflow, lowering differential pressure, and minimizing downtime and maintenance.
