Apparently 2-layer masks aren’t as good as 3-layer masks. The Public Health Agency of Canada released a statement earlier this week stating that Canadians should wear a three layer mask with a filter.
Canada’s Chief Public Health Officer Dr. Theresa Tam stated that adding an additional filter layer will give Canadians extra protection again the ever present coronavirus, COVID-19.
Technically, this could just be a 2-layer mask with a filter between the layers, so you don’t need to throw out your two layer masks. Fit is also very important.
“I keep emphasizing the fit is one of the most important things,” Teresa said. “It fits around your mouth, on your nose, and it has to cover your mouth and nose. So that’s really important.”
As more research continues to be done, we can expect to see changes in recommendations like this often.
