The grade classification of precision filter element is mainly divided according to filtration accuracy and size.

According to the different filtration accuracy, the precision filter can be divided into ultrafiltration filter, nanofiltration filter, reverse osmosis filter and so on. The filtration accuracy of the ultrafiltration filter element is between 0.1-0.01 microns, which can filter suspended substances, bacteria, some viruses, etc.; The filtration accuracy range of nanofiltration filter element is between 0.01 and 0.001 microns, which can filter inorganic salts and heavy metal ions in water. The filtration accuracy range of the reverse osmosis filter element is less than 0.001 micron, which can remove the ion grade impurities in the water and make the water quality close to pure water.

According to the different size, the precision filter can be divided into 0.65 micron, 3 micron, 5 micron, 10 micron, 25 micron and other specifications. These sizes of filter elements can filter out particles of the corresponding size and below, meet the filtration requirements of different processes, and improve the purity of liquids or gases.

In addition, the precision filter element has different materials and structures, such as activated carbon filter element, polypropylene filter element, etc., the filter effect and service life of different materials and structures are also different.

In practical applications, different fields and different production processes have different requirements for filtration accuracy, so it is necessary to select the appropriate precision filter grade according to actual needs. For example, the filtration accuracy of the particle filter is generally more than 5 microns, which can filter impurities such as large particulate matter, sediment and suspended matter; The filtration accuracy of the cloth filter is generally less than 5 microns, which can filter some relatively small impurities; The filtration accuracy of the membrane filter can reach 0.01 micron or less, which is suitable for pure water, electronics and other fields.
