Testing the fit

摘要

Facial structure arid beards are two individual characteristics affecting the fit of a respirator, I have both a beard and sharp, thin facial features, which creates a big problem when buying a suitable respirator. On the other hand, a clean-shaven Santa Claus would be pretty easy to fit with a proper respirator. So buying a respirator is as personal as buying a new pair of shoes: They both have to fit well.
