This 7-stage Reverse Osmosis (RO) system provides the highest level of water purification by combining standard filtration with specialized enhancement stages. It is designed to go beyond basic cleaning, not only removing nearly all contaminants but also improving the water's taste and nutritional profile.
The 7-Stage Process
While configurations vary, a 7-stage system typically follows this progression:
Sediment Filter: Removes dirt, rust, and sand.
Granular Activated Carbon (GAC): Neutralizes chlorine and organic odors.
Carbon Block: Further refines the water and protects the membrane.
RO Membrane: The core stage that strips away up to 99% of TDS (Total Dissolved Solids), lead, and arsenic.
Post-Carbon Filter: Polishes the water as it leaves the storage tank.
Alkaline/Remineralization Filter: Adds essential minerals (calcium, magnesium) back into the water and balances pH levels.
UV Sterilizer or Infrared Stage: Eliminates bacteria and viruses or "activates" the water for better hydration.
