If you are testing N95 masks with evaporated salt particles and measuring that with a very-fine sensor, what instrument or test measures actual viruses? Do hard salt particles and aerosolized viruses behave the same?

SPS30 is an optical scanner (laser) for “dust and other particulates” down to 0.3 micron.
If 0.3 micron is the limit of its capability (resolving power), voila!— 95% of better results while testing an N95.
Picking up even smaller organic matter like a virus?
Doubtful.
