# Fluid resistance represents the mask's resistance to penetration by synthetic blood under pressure (mmHg). A mask or respirator must be fluid-resistant in order to be regarding as surgical use. It measures the ability of a mask's material construction to minimize fluids from traveling through the material and potentially coming into contact with the wearer.

^KN95 is slightly different from N95. It is the Chinese standard for respirator. Please check our standard table on about-us page.
