Material and Filtration Performance

The filter uses advanced trilobal fibers to boost filtration capacity beyond standard fabrics. This design supports deeper penetration of contaminants into the pleats during cleaning, helping the filter feel and perform like new after washing. The overall construction is built to hold shape and position within the housing for steady performance over time.

Maintenance and Longevity

Regular cleaning is encouraged to keep performance high. When you rinse the pleats properly, you can maintain filtration efficiency and reduce the frequency of replacements. A careful cleaning routine can also help minimize water waste while preserving filter structure and fit.
