Originally aired November 13 2020 on CBC Marketplace

Wearing a mask is critical to reducing the spread of COVID-19, but rigorous tests conducted on behalf of CBC’s Marketplace found that while some work very well, others offer little protection from the particles that transmit the novel coronavirus. One type of mask can even spread those particles to others

Sporometrics own Dr. James Scott joined the CBC Marketplace investigators to test out various types of masks based on materials, thickness, and whether masks with vents contained an added advantage. Find out which ones passed the test and which ones you should avoid using here
