"Mesh Size And Filtration Accuracy?"

"Is mesh size equal to filtration accuracy?"

Instead of mesh size, we usually use filtration accuracy, which is defined as a filtration efficiency of 98% when intercepting particles of a certain size.

Filtration accuracy and true pore size are actually not the same, usually smaller than the true pore size.

What is seen through the scanning electron microscope scanning image is only the surface holes, under the effect of the thickness of the filter disc, the pore space meanders, and the real holes are smaller than the holes seen.

In addition, we check the pore size with a bubble point and pore size analyser to ensure quality issues.
