Airborne transmission of COVID is sexy, requiring solutions like this, and individual impositions like wearing masks which are easy to police.
But I think the more likely spread of COVID is from mundane surface transmissions. One of the 'mystery' COVID cases in New Zealand was eventually tracked to people touching the same elevator button about an hour apart, for example.
Same here in Europe - everyone is wearing masks, but how many times is the apartment entrance handle touched by people each day?
