Filter Function

First stage: PP cotton (PPE filter with a pore size of 5 microns): Preliminary filtration of raw water to remove coarser particles, colloids,  suspended soilds, etc. in the water.

Second stage: Granular activated carbon: high-effciency adsorption of odor, color, organic matter, and heavy metals in water.

Third stage: Compressed activated carbon: further remove residual chlorine, organic compounds, color, odor, turbidity, etc.

The fourth stage: Ro reverse osmosis membrane: 0.0001 micron pore size, effectively removes organic impurities such as viruses and heavy  metals in water.

The fifth stage: Deionization purification column: remove most of the heavy metals and trace elements in the water,and the water quality meets the national laboratory water first grade water standred.
