HEPA (High-Efficiency Particulate Air) is a foreign name. There are many kinds of materials for HEPA filters, which can be divided into PP (polypropylene) filter paper, PET filter paper, PP and PET composite filter paper and glass fiber filter paper. Among them, PP (polypropylene) is paper, so it generally cannot be washed. Another part of the HEPA filter uses HEPA air filter paper made of PET or PTFE. This is the origin of many claims on the Internet that water-washable HEPA filters are used, but this type of HEPA filter is less efficient.
Hippa is a filter that can block extremely small dust. According to the current level, it is divided into G1-G4, F5-F9, H10-H14 and U15-U17. Commonly seen in air purifiers is the H-level filter, which meets the HEPA standard. The efficiency of 0.1 micron and 0.3 micron is 99.7%. The characteristic of the HEPA network is that air can pass through, but small particles cannot.
The currently independently developed HEPA air filter paper is the core filter material of the HEPA filter, with a reliable filtration level of H13-U16. It has low wind resistance and low energy consumption, and can meet the filtration efficiency level requirements of various air filters with different efficiency levels, and is highly recognized by customers!
