How to judge whether the efficiency of industrial hepa filters meets the standard?

What is the filtration efficiency of industrial hepa filters? Many people will say "I use the filter filter grade is H13", then what is the evaluation standard of high efficiency filter H13? How do I know if the filter you provide is H13 efficient and up to standard? Specific air filter manufacturers for your analysis:

First of all, let's understand the classification of industrial hepa high efficiency filters:

H10(EN18822) : ≥85%@MPPS(≥90%@0.3UM);

H11(EN18822) : ≥95%@MPPS(≥99%@0.3UM);

H12(EN18822) : ≥99.5%@MPPS(≥99.9%@0.3UM);

H13(EN18822) : ≥99.99%@MPPS(≥99.99%@0.3UM);

H14(EN18822) : ≥99.995%@MPPS(≥99.999%@0.3UM);

Through the above, it can be understood that the efficiency of the high efficiency filter H13 is 99.99.

Industrial hepa High efficiency filter testing and acceptance standards: There are three national standards for the detection and acceptance of high efficiency filters, including "Efficiency and resistance of GBT 6165-2008 High Efficiency Air filter Performance Experimental Method", "GB-T 13554-2008 High Efficiency Air filter", foreign standards include cGMP, the United States "IEST-RP-CC034", "High Efficiency Air filter", "High Efficiency air filter". The European Union's "EN1822", "ISO14644-3 clean room and its controlled environment measurement and test method", each standard puts forward the leak detection method and acceptance standards of high efficiency filters are different.

As for the quality concerns raised by the customer, the normal manufacturer can provide the certificate and the factory test report when shipping, if the test fails after installation, you can contact the manufacturer to confirm the cause, and then check other reasons, you can also send to the third-party testing institution to determine whether it is a product quality problem, if it is a quality problem, you can directly contact the manufacturer to deal with.
