Illustration of installation sequence of five water purifier filter elements

The installation sequence of the five water purifier filter elements is as follows:

Material: complete water purifier

Tools: complete filter element of water purifier

1, the first stage is 5 micron PP cotton filter element, also known as polypropylene melt-blown filter element, which is made by polypropylene melt-blown process and mainly filters rust, sediment, rubber eggs and other substances in water.

2. The second stage is granular activated carbon filter, which further removes residual chlorine through rust, sediment, colloid, eggs and other substances in water, reduces the turbidity of water, and removes odor and abnormal color.

3. The third stage is compressed activated carbon filter, also called CTO filter, which can further reduce the turbidity of water, remove residual chlorine, odor and organic matter, and improve the taste.

4. The fourth stage: the fourth stage of some double-membrane models is the ultrafiltration membrane filter element, which can effectively reduce the turbidity of water and remove organic matter and bacteria. Reverse osmosis RO membrane filter can also effectively remove organic matter, inorganic matter, bacteria, calcium and magnesium ions, heavy metals and so on in water. The fourth stage of ultrafiltration machine is ultrafiltration membrane, which can effectively reduce the turbidity of water and remove organic matter, bacteria and so on.

5, post-activated carbon, further remove odor, effectively improve the taste.
