How Domestic RO Systems Work

  1. Pre-Filtration Stage – Includes a sediment filter and activated carbon filter to remove large particles, chlorine, and odors.

  2. RO Membrane Stage – The heart of the system where water passes through a semi-permeable membrane, removing dissolved salts, heavy metals, and contaminants.

  3. Post-Filtration Stage – Includes additional carbon filters, mineral cartridges, or alkaline filters to enhance taste and add essential minerals.

  4. Storage & Dispensing – The purified water is stored in a tank and dispensed through a tap for use.
