How Waternium S3 Cartridge Works
STAGE 1 — SEDIMENT DEFENSE: 5-micron sediment barrier designed to capture suspended solids and protect internal media for sustained flow integrity.
STAGE 3 — HEAVY METAL FILTRATION: Advanced nano-ceramic media targets removal of heavy metals (Lead, Arsenic).
STAGE 2 — CHEMICAL ADSORPTION: High-density sintered carbon reduces Chlorine and other chemicals while maintaining flow integrity under high demand.
