A 6-stage Reverse Osmosis (RO) system typically includes the following stages to ensure thorough water purification:

1. Sediment Filter: Removes large particles like sand, rust, and silt.
2. Carbon Pre-Filter: Reduces chlorine, organic compounds, and improves taste and odor.
3. Carbon Block Filter: Further reduces chlorine, organic chemicals, and other contaminants.
4. RO Membrane: The heart of the system, removes up to 99% of contaminants including bacteria, viruses, and heavy metals.
5. Post-Carbon Filter: Polishes the water, removing any remaining impurities and improving taste.
6. Remineralization Filter: Adds essential minerals back into the water to improve its taste and balance its pH level.
