Non-medical masks now recommended for Canadians, officials say

Wearing non-medical masks when in public as an additional measure to avoid spreading droplets in addition to social distancing.

You can wear face masks that cover the nose and mouth for protection from the environment or to prevent spreading your bugs to others. But not all masks are created equal.

If you are shopping for a mask to stop the spread of an infection to your family or colleagues, look for a surgical mask that consists of two or more layers of flat or pleated fabric. A good quality mask generally has a three-ply layer with the innermost layer used for absorbing moisture, the middle layer is a filter and outermost layer repels water.
