HeiQ Viroblock

Special fabric for non-medical face masks (“community masks”) with effective antimicrobial and antibacterial properties

Which masks protect against corona?

Any mask protects against infection to a certain degree, however, the effectiveness of a mask and the contexts in which their use makes sense depends of the type of mask. To protect against small aerosols, what are known as FFP masks must be worn that are at least protection class 2, but 3 is best.

A surgical face mask only really protects against larger droplets and is used in situations in which the wearer might come into direct contact with another person’s bodily fluids. They are also worn to protect others from the wearer’s bodily fluids. That means surgical face masks are a measure that is often more about protecting others than about protecting the wearer.
