Material and filtration performance

The filter uses advanced trilobal fiber technology to deliver higher capacity and robust filtration compared to standard fabrics. This construction supports deeper pore penetration and a stronger pleat structure, which can help maintain clear water by capturing more debris during each cycle. The combination of end caps and pleats is designed to stay in place and resist deformation during use.

Easy cleaning and maintenance

The filter is designed for easier maintenance. The improved trilobal fabric structure supports deeper penetration of impurities into the pleats, and washing can refresh the element so it feels like a brand-new unit after cleaning. It is recommended to clean the cartridge when the pressure gauge reaches the predetermined value to help maintain optimal flow and performance.

Durability and value

Durable end caps and sturdy pleats contribute to a reliable fit and long-lasting filtration. Regular cleaning can help extend service life and minimize unnecessary water usage, providing a more efficient maintenance routine for spa enthusiasts who value consistency and convenience.
