Mann+Hummel has announced that the majority of its cabin air filters now meet the requirements of CN95 certification, which is based on test standards previously developed by the China Automotive Technology & Research Center Co. Ltd.
CN95 certification is setting new standards in the cabin air filter market, although it is not yet a mandatory requirement for the sales of cabin air filters in China.
The main requirements for certification are pressure drop, dust holding capacity and fractional efficiency. In the meantime, limits were slightly modified for the additional certification of odour and gas adsorption. To reach the upper CN95 efficiency level (TYPE I), the media used in the cabin filter needs to filter out more than 95% of particles with a diameter larger than 0.3 µm. This means that fine dust particles, bacteria and virus aerosols can be blocked.
Since early 2020, Mann+Hummel has been supporting OE customers successfully with CN95 certification which can be only applied for at a subsidiary of the China Automotive Technology and Research Center (CATARC), the CATARC Huacheng Certification (Tianjin) Co., Ltd.
