Most air purifiers and fresh air purifiers currently on the market use HEPA filters, but HEPA filters with the same name have different purification effects.
Purification level and production materials are both decisive factors, and users should check the products when purchasing. There are many choices for HEPA air filter paper. According to type, it can be divided into PP filter paper, composite PET filter paper, melt-blown, polyester non-woven melt-blown, glass fiber and other materials. HEPA filters, etc. are subdivided into G1-G4, F5-F9, H10-H14 and U15-U17 according to the current foreign grades. H-level filters are commonly seen in air purifiers. HEPA filters of this size are all high-efficiency filters. The H13-14 filter, which is recognized as a very good filter, is an air filter. Among them, the H13 grade HEPA filter can achieve a total efficiency of 99.95. The total efficiency of H14 grade HEPA filter can reach 99.995%.
The HEPA air filter paper currently produced is a variety of filter media products that undergo a special post-finishing process and are coated with PTFE on the surface (Polytetrafluoroethylene) microporous membrane. This filter material uses PTFE microporous membrane to filter dust in one time, which greatly improves the filtration effect of the filter material product. The surface is smooth and resistant to chemicals. It is laminated to the surface of ordinary filter materials and functions as a disposable dust layer. All dust is trapped on the surface of the membrane to achieve surface filtration.
PTFE film manufacturer specializes in the production of HEPA air filter paper. It has a full set of advanced production equipment and technology, and also has advanced clean rooms and The independent composite slitting workshop ensures the production quality of PTFE membrane; the product materials produced are all imported raw materials, with high uniformity, stable performance, and the filtration efficiency can reach 99.999995%! . You are always welcome to come to the company for inspection or enter the store to consult with us.
