PP filter element, also known as melt-blown PP filter element, is a tubular filter element made of non-toxic and odorless polypropylene particles through heating, melting, spinning, traction, and forming; if the raw material is mainly polypropylene, it can be called PP melt-blown pp filter.

Features of PP filter Cartridge

Features of PP filter Cartridge

This kind of PP filter element
  1. This kind of PP filter element has a very high filtration accuracy. It has undergone stricter production technology to make the quality of the product extremely stable and reliable. Its filtration capacity is also larger than other filter elements, and the pressure loss is small.


  1. This kind ofPPfilter element has a long service life and its cost is not very high. It is mainly in the structure, which is completely tight inside and loose outside, which guarantees the amount of pollution and prolongs the lifespan.


  1. Absolute corrosion resistance and a wide range of applications. Since this PP filter element is composed of only one material, it is absolutely stable in nature, making it highly corrosive.


Application field of PP Filter cartridge


The application range of PP filter cartridge is extremely wide. It can filter liquid and compressed gas in pure water, solvent, pharmaceutical industry, electronics industry, petrochemical industry, food and beverage and other industries.

pre-filtration of some injections

For example, in the pharmaceutical industry, pre-filtration of some injections, liquid medicines and injection bottle washing water, pre-filtration of large infusions, various antibiotics, and Chinese medicine injections. The food industry includes the filtration of alcohol, beverages, and drinking water. Petroleum and chemical industry, filtration of various organic solvents, acids, lye, oilfield water injection filtration. Electronic industry, pre-filtration of pure water and ultra-pure water.


How to identification of the quality of PP filter cartridge?


The quality of the PP filter cartridge is determined by the tightness of its fibers. The inner fibers of the high-quality PP filter element are tight and uniform. And this difference can not be seen with the naked eye at the time of purchase. How should we distinguish it?

the higher the fiber density of the filter element

First: look at the weight. We can measure the weight with our hands. The heavier the weight, the higher the fiber density of the filter element. The quality is also better.


Second: look at compressibility. Generally, the higher the fiber density of the filter element. The better the compression performance, the better the quality of the PP filter element. We can judge by hand, the stronger the hand, the better the compression performance.


Third: look at the material. When choosing a filter element, you must be optimistic about the material of the filter element. The color of the regular filter element filter paper is uniform and the paper surface is flat. The inferior filter paper is not uniform in color and poor in texture.


Fourth: Look at the colloid. The regular filter element has good gel quality and good elasticity, while the inferior filter element has soft rubber and poor texture.


The above two points may not be used when we buy a new water purifier system, but we can come in handy when we purchase the PP filter cartridge separately.

The service life of PP filter cartridge

1 accuracy

1 micron (um), 10 micron (um), 20 micron (um), 50 micron (um)

The higher the accuracy, the shorter the service life, but the filter medium is more thorough. Due to the turbidity of the filter medium (fine particles, etc.), the filter element is easier to be dirty. Once the filter element is dirty, its service life will be affected.

the normal replacement time is 3-6 months

2 water quality

The replacement time is determined according to the water quality of different raw water. Generally, the normal replacement time is 3-6 months.
