The implementation standards of air filters are usually specified by the relevant international, industrial or national standards bodies. These standards are designed to ensure that the performance and quality of air filters meet specific requirements to safeguard the health of users and the normal operation of equipment. The following are some common air filter execution standards: 1.ISO 16890: This is a standard issued by the International Standards Organization (ISO), which specifies the procedures and methods for air filter performance evaluation, including the performance grade of particulate filters. 2.EN 779: Standard published by the European Committee for Standardization (CEN) for evaluating the particle capture efficiency of air filters, based on particle size. ASHRAE 52.2: A standard published by the American Society of HVAC and Refrigeration Engineers (ASHRAE) for testing and evaluating the performance of air filters, including particle capture efficiency. 4.GB/T 14295: China national standard, which specifies the performance test methods and requirements of air filters. When selecting air filters, it is important to know the implementation standards in your region or field of application. This helps to ensure that the selected air filter element meets the requirements of the specific industry or country and can provide good filtration results.
