Klearflow KF17 6-Layer Replacement Filter Cartridge 1 Micron - Fits Puretec Puremix Z7 NZ

Six-layer filtration for harsh, high-sediment water.

The Klearflow KF17 is a 17" replacement cartridge built for low-pressure, high-sediment supplies. It uses six layers of filtration to reduce sediment, chlorine, chemicals, heavy metals and scale — all in a single quick-twist cartridge.

It's designed for harsh and rural water and suits mains, council, tank and bore supplies. The cartridge fits directly into the Puretec Puremix Z7 system and retrofits other Puremix Z Series and Pentair Everpure systems. For household, indoor use.

Rated for up to 75,000 litres or 24 months, whichever comes first, the KF17 is a long-life cartridge that filters down to 1 micron. The quick-twist design makes changeovers fast and clean — no spanners, no mess.

How it works

Water passes through six layers in sequence. Sediment is captured first, then the anti-bacterial ball, carbon block and KDF media reduce bacteria growth, chlorine, chemicals and heavy metals. The final scale-control layer helps prevent calcium and hard-water minerals from building up in your pipes and appliances. The result is cleaner, better-tasting water with fewer contaminants.
