How the Four-Stage System Works

Stage 1 — Sediment Pre-Filter

A 5-micron sediment pre-filter (SED-P5) helps capture sediment and suspended particles before water reaches the subsequent filtration stages.

Stage 2 — Carbon Filtration

The carbon filter (DW-CB10) helps reduce chlorine-related taste and odor while preparing the water for reverse osmosis treatment.

Stage 3 — Reverse Osmosis Membrane

The reverse osmosis membrane (ROM-100) separates water from a range of dissolved substances through a semi-permeable membrane.

Stage 4 — Final Post-Filter

The final post-filter (CTO-110) provides an additional polishing stage before treated water reaches the dedicated drinking-water faucet.

Installation and Maintenance

The system is designed for under-counter installation and includes a water storage tank, lead-free faucet, and installation components.

Professional installation is recommended.

Routine maintenance includes periodic replacement of the sediment and carbon filters, servicing of the RO membrane, and inspection of the system's connections and storage tank.

Replacement intervals depend on water quality, usage, and operating conditions.
