Created by layering melt-blown polypropylene fibers in a continuously gradient structure. Produced in water grade, high performance grade, and absolute grade.

Water Grade – 80% efficient. Free of additives, wetting agents, binders, and silicone. Big Blue Series (4.5” diameter) available.

High Performance Grade – 90% efficient. Resists contaminant unloading, even at elevated differential pressures.

Absolute Grade – 99% efficient. Precision process control of fiber diameter and layer density tunes the media to achieve targeted retention efficiency and ensure consistent performance.
