What percentage of Micro organisms are blocked by masks? Surgical masks have a filtering capacity for 90 percent of microorganisms, including (the virus). For FFP2 masks used in intensive care, this capacity increases to 98 percent, 99 percent. For fabric masks, it is lower, estimated to be between 50 percent and 70 percent.

This is confirmed by guidelines set out by the Canadian government for the production of masks and respirators.
