Filtration Stages

Stage 1: 5 Micron PP Filter

Replace every 3 - 6 months. The Polypropylene (PP) primary defense stage designed to remove all suspended matter such as dirt, silt, rust, sand, and scale particles. This essential first step protects the subsequent carbon filters and the RO membrane.

Stage 2: 5 Micron GAC Filter

Replace every 3 - 6 months. The Granular Activated Carbon (GAC) filter tackles herbicides, pesticides, chlorine, and organic chemicals to improve taste and protect the membrane.

Stage 3: 5 Micron CB Filter

Replace every 3 - 6 months. The Carbon Block (CB) filter provides a secondary layer of defense, further reducing chlorine, chloramines, and chlorine by-products before the water reaches the critical reverse osmosis stage.

Stage 4: Aquaporin Reverse Osmosis Membrane (0.0001 Micron)

Replace every 2 years (or after 7,000 litres). The heart and soul of this 6-stage system. This Reverse Osmosis Filter for Philips Tap Water Stations features a biomimetic RO membrane equipped with NASA/ESA tested Aquaporin Inside™ water purification technology to filter water faster and more energy efficiently. Replicating nature's own water filtration process, this purifying excellence removes 110 kinds of harmful substances down to 0.0001 microns, including heavy metals, microplastics, and PFAS.

Stage 5 & 6: Post-Reverse Osmosis Carbon Block Mineral Cartridge

Replace every 12 months (or after 3,650 litres). Because reverse osmosis strips water of its natural minerals, this vital final stage enhances purified water with beneficial minerals such as Calcium (Ca2+) and Magnesium (Mg2+). This pH-balancing Carbon Block filter reintroduces healthy minerals back into the purified water, improving the pH balance and delivering a crisp, natural taste ideal for drinking and cooking. Designed specifically for the Philips AUT9510.
