HEPA filter media test
In our factory, we can test the efficiency, pressure drop of HEPA filter media ( PTFE material ), by testing the filter media performance, can know the performance of HEPA filter we are doing now. Also, the testing can let our ensure the material quality we are using.

As you can on the test result, the efficiency is 99.97% @ 0.3 micorn, flow rate is 32.1L/min and pressure drop is 2.5 mm H20.
After getting the data, we can know the proximately data of HEPA filter we are making.
