Epidemiologist Cynthia Carr gives us a mask breakdown. A look at the KN95 mask and why it's much more effective than others.

As COVID-19 continues to evolve, so does masking up.

To remedy any confusion that might be surfacing around masks as the Omicron variant circulates, here’s a run-through of the different types available, how to use them correctly and where to find them.

Homemade cloth mask:

Ineffective if worn as a single layer.
If nothing else is available, Health Canada recommends they be worn as two tightly woven cloth layers with a filter between.
Ensure mask has a snug fit.
Wash hands before and after adjusting the mask, putting it on and taking it off.
Store in a clean paper or cloth bag between uses.
Wash in soapy water after each use.
Dispose of the filter layer after each use.
Available commercially.

Medical mask:

Somewhat effective on their own, but gaps on the side of the mask don’t provide the best seal.
Best worn with a cloth mask over top for proper fit.
Wash hands before and after adjusting the mask, putting it on and taking it off.
Store in a clean paper or cloth bag between uses.
Typically single-use, but can be reused until visibly damaged, dirty or damp.
Available commercially.

KN95 mask:

Effective due to the fit and filtering capabilities.
Highly similar to the N95 respirator; the main difference between the two is the manufacturer.
Wash hands before and after adjusting the mask, putting it on and taking it off.
Store in a clean paper or cloth bag between uses.
Can be reused until visibly damaged, dirty or damp.
As of now, difficult to find in Winnipeg.

N95 respirator:
