Filter function

² First stage: PP cotton (PPF filter with a pore size of 5 microns): Preliminary filtration of raw water to remove coarser particles, colloids, suspended solids, etc. in the water.

² Second stage: Granular activated carbon: high-efficiency adsorption of odor, color, organic matter, and heavy metals in water.

² Third stage: Compressed activated carbon: further remove residual chlorine, organic compounds, color, odor, turbidity, etc.

² The fourth stage: RO reverse osmosis membrane: 0.0001 micron pore size, effectively removes organic impurities such as viruses and heavy metals in water.

² The fifth stage: Deionization purification tank: remove most of the heavy metals and trace elements in the water, and the water quality meets the national laboratory water first-grade water standard.
