”Which masks fulfill their promise?”

In collaboration with the laboratory of the Fachhochschule Nordwestschweiz (FHNW), Swiss consumer advice portal Beobachter tested and evaluated 12 masks and found the Livinguard Pro Mask to be the best re-usable, washable mask in the test. Test criteria include: protection against droplets and aerosols, breathability and cost.
