The TOKIT 6-stage reverse osmosis system provides advanced water filtration through 6 different layers, each with a specific function to ensure safe, clean drinking water: Pleated PP cotton: This layer filters out large particles such as sand, rust, and other sediments. Activated carbon: Removes odors, prevents scale buildup, and extends the life of the RO membrane. ROmembrane: This stage eliminates microorganisms, bacteria, and heavy metal ions, ensuring that the water is free of harmful contaminants. Coconut shell carbon rods: This layer further enhances the taste of the water by absorbing any remaining odors and impurities. Strontium-enriched rock membrane: Adds beneficial minerals to the water, improving water quality and nutritional value. High-density non-woven fabric: Protects the core filter element and extends the overall life of the filter.By combining these six stages, the TOKIT RO system can effectively purify water, making it safe and healthy to drink.
