These Triple Layer masks meet community standards all over Canada. As I get more information on how to make the best masks, I will continue to update them. At this time they are adjustable with replaceable elastics. They have a nice firm nose wire and can be altered under the chin to fit around your face better (include that request in your order for free).
Helen Mends has been working with the ROSE project (https://www.roseproject.ca/) through COVID to make a reusable hospital grade mask. These masks don't yet meet that standard but we will continue to update them as we get closer.
Adjustable Triple Layer Mask
Current mask version is two layers of polypropylene, one layer of cotton. These masks should be hand washed in warm water of put in boiling water for three minutes.
