"I was able to successfully purchase some. Have them shipped overnight," Murray said. "It's my hope today that people come in and get the mask just take a deep breath and relax and know everything else is going to be OK."

Believe it or not, experts said that by wearing a mask, you could be putting yourself even more at risk.

"People do not use their masks correctly," Eisenman said. "They play with it. They wear it too long. They rub their nose underneath it.
