Aqualite PP5M20BB polypropylene string-wound cartridge removes large particles like sand, rust, silt, and clay from water. The tightly wound thread forms a multilayer barrier that traps impurities step by step while keeping a steady flow. This filter works like a strong dirt trap — letting only clean, clear water pass through.

Where and how it’s used

Maintenance
