Features

Precision filtration. Equipped with a 0.0001-micron RO membrane, it can effectively remove heavy metals, bacteria, viruses, and other harmful substances from water. The filtered water quality is close to pure water, almost free of impurities and pollutants, truly achieving health and safety.
Multi-stage filtration. Multi-stage filter design includes a 10-inch pre-PP cotton filter cartridge, granular activated carbon filter cartridge, compressed activated carbon filter cartridge, RO membrane filter cartridge, and post-activated carbon filter cartridge, purifying water quality layer by layer.
Compact design. With a compact structure and reasonable design, it is relatively small in size, making it particularly suitable for installation under the kitchen sink without occupying additional home space, while maintaining ease of maintenance.
Stable water supply. The filtered pure water is stored in a storage tank, which can provide a stable water volume during peak times, ensuring a steady supply of pure water in a short period.
Low maintenance cost. The storage tank reduces the working time of the pump, thereby extending the service life of the water pump and RO membrane, reducing long-term maintenance costs, and saving expenses for household users.
