6-Stage Ultrafiltration Water Purifier
A compact under-sink filtration system designed for ambient drinking and cooking water in homes, apartments and offices. The system operates using normal inlet-water pressure and requires no electricity.
Six-Stage Filtration Process
- PP Sediment Filter: Serving as the initial pretreatment stage, this filter effectively captures large suspended particles. It removes sand, silt, rust, colloidal impurities, and organic pollutants to deliver cleaner water and protect downstream filters.
- UDF Granular Activated Carbon: This stage significantly improves overall water quality by targeting chemical contaminants. It effectively removes residual chlorine, and organic impurities while adsorbing unusual colors and unpleasant odors.
- CTO Carbon Block: Serving as an advanced secondary purification stage, this solid carbon block utilizes deep adsorption to further reduce chlorine, and unpleasant tastes and odors, providing a thorough final polish to the water.
- UF Ultrafiltration Membrane: Utilizing a 0.01-micron pore size, this advanced membrane provides ultra-fine physical filtration. It effectively intercepts harmful substances, including bacteria and E. coli, while allowing beneficial, naturally occurring dissolved minerals to remain in the water.
- EED Mineral/Alkaline Cartridge: Serving as the final conditioning stage, this cartridge enriches the water with beneficial minerals while gently adjusting the pH to an optimal alkaline level. (Note: Exact pH and mineral levels will vary based on the incoming water source and the filter’s condition).
- 33 Post-Carbon Filter: Acting as the final polishing stage before dispensing, this refined carbon filter provides ultimate taste and odor improvement. It expertly conditions the water to ensure a clean, smooth, and naturally sweet finish.
Recommended Filter Replacement Schedule
| Filter | Recommended Replacement Interval |
|---|---|
| PP Sediment Filter | 3–6 months |
| UDF Granular Activated Carbon | 6 months |
| CTO Carbon Block | 6 months |
| UF Ultrafiltration Membrane | 12 months |
| EED Mineral/Alkaline Cartridge | 12 months |
| T33 Post-Carbon Filter | 6 months |
Replacement intervals vary depending on incoming water quality and daily usage.
Note: This product is designed primarily for city water. As an ultrafiltration system, it does not reduce dissolved salts or TDS in the same way as a reverse-osmosis system. Flush new filters ~30 minutes thoroughly before first use.
Warranty: 1-year warranty against manufacturing defects.
