Description of Pure Touch 7-stage full set Combo Package – (Vietnam)
| Stage | Cartridge Type | Core Function |
| 1st Stage | Wellsys PP Sediment Filter (Polypropylene) | Pre-filtration. Removes large suspended solids like dirt, rust, sand, and silt. Protects subsequent filters, especially the carbon stages and RO membrane, from premature clogging. |
| 2nd Stage | Pure Touch GAC Filter (Granular Activated Carbon) | Pre-treatment. Adsorbs chlorine, bad taste, odors, and VOCs (Volatile Organic Chemicals). Essential for protecting the delicate RO membrane from chlorine damage. |
| 3rd Stage | Pure Touch CTO Filter (Carbon Block) | Enhanced Pre-treatment. A compressed carbon block that removes remaining chlorine, fine particles, and organic compounds for superior RO membrane protection. |
| 4th Stage | Wellsys RO Membrane | Primary Purification. The core stage. It filters water through microscopic pores, rejecting up to 99% of Total Dissolved Solids (TDS), including heavy metals, salts, bacteria, and viruses. |
| 5th Stage | Pure Touch T&O Filter (Taste and Odor / Post-Carbon) | Polishing. Removes any residual tastes or odors the water may have picked up during storage in the RO tank, ensuring a final clean taste. |
| 6th Stage | Wellsys Mineral Filter (or Mineralizer) | Enhancement. Reintroduces essential healthy minerals (like calcium, magnesium, and potassium) that were removed during the RO process. This is vital for making the water healthier and improving its taste. |
| 7th Stage | Pure Touch Alkaline Filter (or pH Balancer) | pH Correction. Elevates the pH level of the purified water, making it less acidic (more alkaline). This is a popular feature desired by many consumers for potential health benefits. |
