However, he noted: surgical masks have special webs with charged surfaces. The so-called electrostatic forces. The filter performance of these membranes can increase, without increasing the resistance.
“Therefore, surgical masks have a good filter performance and a relatively low breathing resistance. These electrostatic forces lose, however, if moisture comes into play – for example, after a long Wear.
