One could built UV-Lightmasks.
A transparent hose, add UV-LEDS to sterilize the flowing air. Dry the air at the start with silica gel. All that is needed then is a battery.
The silica gel can be heated every once in a while to loose any moisture bound it and sterilize virus particles attached to it.
