Stage 1 – Sediment Guard™ 25-to-1 Micron Prefilter A dual-gradient sediment filter that starts at 25 microns on the outside and tightens to 1 micron on the inside. This progressive design captures sand, rust, and silt effectively while extending the life of downstream filters.

Stage 2 – AquaShield™ Carbon Block A 1-micron high-flow carbon block that reduces chlorine, PFAS, pesticides, herbicides, pharmaceuticals, and bad tastes and odors—delivering fresh, great-tasting water from every faucet.

Stage 3 – NanoPak® Electropositive Biological Filter Powered by NASA-developed Ahlstrom Disruptor® media, the NanoPak® provides 6-log bacteria, 4-log virus, and 3-log cyst reduction. It also reduces heavy metals, PFAS, microplastics, and other chemical pollutants, ensuring advanced biological protection for your home.
