RO Water Purifier – Pure Drop by Drop, Safe for Direct Drinking

The RO water purifier is a device that uses reverse osmosis technology for water purification. It consists of pre-filter cartridges, a RO filter cartridge, post filter cartridges and a storage tank. Through the precise filtration of the RO membrane at 0.0001 microns, harmful substances such as heavy metals, bacteria, viruses, and chemical pollutants in the water are effectively removed. The water filtered by the RO water purifier can meet the needs for daily drinking, cooking, and making tea. Additionally, the RO water purifier features a compact design, making it easy to install under a sink.

Paired with a storage tank, it can reserve purified water, ensuring sufficient supply even during short-term high-demand periods. This makes it ideal for large family or shared office spaces with high water consumption.

Structure
  1. PP cotton filter cartridge: First-stage filtration, it removes large particles in the water, such as sand, sediment, and suspended solids.
  2. Granular activated carbon filter cartridge: Second-stage filtration, it adsorbs odors, chlorine, and organic compounds in the water, improving its taste.
  3. CTO filter cartridge: Third-stage filtration, it further removes residual odors, heavy metals, and other contaminants from the water.
  4. RO membrane filter cartridge: Core filtration, it removes heavy metals, bacteria, viruses, mineral salts, and other impurities from the water.
  5. Post-activated carbon filter cartridge: Fifth-stage filtration, it enhances the taste of purified water.
  6. Booster pump: It pressurizes the water to pass through the RO membrane.
  7. Solenoid valve: It controls the flow and interruption of water.
  8. Faucet: It is a device for dispensing purified water.
  9. Pressure storage tank: It stores purified water.

Features
  • Precision filtration. 0.0001-micron precision filtration makes water quality after filtration close to pure water, with almost no impurities or contaminants.
  • Multi-stage filtration. Multi-stage filter design including pre PP cotton filter cartridge, RO membrane, and post-activated carbon filter cartridge, purifies water layer by layer.
  • Miniaturized design. Compact structure, small size, suitable for installation under the kitchen sink, without occupying too much space.
  • Stable water output. The filtered pure water is stored in the water storage tank, ensuring a stable supply of pure water in a short time.
  • Low maintenance cost. The water storage tank reduces the working time of the pump, relatively extending the lifespan of the water pump and RO membrane.
