what is known as the bubble point test. This reveals the porosity level and consistent texture of the filter st air bubble rises to the surface, or the higher the air pressure, the finer the pores in the filter.


Major American manufacturer: It was noticeable here that five out of six test specimens showed leakage from the end cap.


Pirated version: The pirated version gave the poorest result in this test. A particular weak point was leakage around the adhesive. On one test specimen the adhesive was missing altogether.
