Smith quoted on double COVID masks

AirUCI faculty Jim Smith is quoted in a Mashable article on the effectiveness of double masks for the prevention of disease transmission in the era of COVID.

"It leaks like a sieve, it leaks like crazy," said Jim.  "Surgical masks need a way to seal better around your face. That's the whole point of double masking, in my view."   Read the artocle
