pp cotton filter, also known as melt-blown pp filter, is a tubular filter element made of non-toxic and odorless polyester fiber particles after heating, melting, spinning, pulling, and receiving forming; if the raw material is mainly polyester fiber, it can be It is called PP meltblown filter element.

Functions and Features
1. Can effectively remove various particulate impurities in the filtered liquid;
2. It can be multi-layered deep structure and has a large amount of dirt;
3. The filtration flow is large and the pressure difference is small;
4. Does not contain any chemical adhesive, more hygienic and safe;
5. Resistant to acid, alkali, organic solution and oil, with good chemical stability;
6. It integrates surface, deep, coarse and fine filtration; it has the characteristics of large flow, corrosion resistance, high pressure resistance and low cost. It is used to block large particles such as rust, sediment, and insect eggs in the water.

PP cotton filter element is a filter element that integrates surface filtration and deep filtration. Primary filters are included in fine filtration. It has the characteristics of corrosion resistance, high pressure resistance, large flow rate and low cost. Therefore, in many water purifiers, it is responsible for the first stage of filtration.
However, since the PP cotton filter element is 80% of the filtration effect of the water purifier, especially the large particle impurities, the filtration task is very heavy, so the service life of the PP material filter element is very short, and the poor water quality area needs 3-4 months Replace the filter element. The area with better water quality should not exceed 6 months. It is mainly based on the actual situation to determine whether to replace the filter element.
Therefore, the PP cotton filter element plays an important role in the filtration mechanism, preventing the blockage of the latter filter element and ensuring the overall effect of the entire filtration system.
