    Product introduction

       HEPA filter screen series is the main filter screen used by most air purifiers and fresh fans at present. It is mainly used to filter small molecule dust and various suspended solids with a diameter of less than 0.3 μ M. HEPA filter screen is subdivided into G1-G4, f5-f-h10-h14 and u15-u17 according to the current European level. The most common level in air purifiers is grade H, among which grade H13 HEPA filter screen can achieve a total efficiency of 9 9.95%, h14 HEPA filter can just reach 99.995%, the highest purification level of HEPA filter in European standard is u, and the total purification efficiency of the best U17 HEPA filter can even reach 99.99997%, but because the production cost of u HEPA filter is high, and the requirements of production environment are very strict, so there are not many wells in the market. In addition to grade, HEPA screens are made of different materials.
