Masks Available in Bulgaria Have Different Protection Level
"There is a wide choice of protective masks on the market. FFP2 and FFP3 differ in protection level. FFP2 protects against all particles and microorganisms at about 94%. FFP3 is safe at about 98-99%," said Chair of the Association of Pharmacy Owners Nikolay Kostov.
"Ordinary hygiene masks, and surgical ones are loose -fitting. That's why they're not designed to provide as much protection as the others," he said.
Kostov also explained that the shape of the FFP2 and FFP3 masks resembles a cup, so as not to touch the lips and when wetted not to be a threat to the person wearing it.
