Every standard (NIOSH/US, China, Korea) has some unique variables when it comes to their test spec for certification.
That being said, in a very broad sense, the "95" number is to set a minimum target for filtration efficiency (for a particulate size defined in the test spec), with actual products hopefully being higher than that number

If you want to doubt the effectiveness of Chinese masks, compare the cases here in U.S. with China. If they don't work, even with the strict quarantine policies, China's number would be much higher than it is now.

I don't know how this mask is. ZISUN is big in air filtration and insulation.
