Pack of 2 Reusable 3 Layer Cotton Face Masks ... - amazon.ca
The mask has 3 cotton layers and a filter pocket which according to medical officers is a good mask for keeping the virus out and in. I like the filter pocket as it is easy to insert a filter. I use polypropylene. What I really like is the mask is easy to wash and dries overnight. I hang it on a clothes hanger or it can be set on a clean area.
