That says, "The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean
room. "

so, it sounds very good. The outcome you want for ensuring your filter is really good is to
see few particles when flooding the filter intake side seams with a certain size of micrometer spheres
to see if any or 'how many' get through. $16 in small quantities is a good price.

Thanks for this lead to finding components.
