Answer:
Fabric masks should be made of three layers of fabric:
Inner layer of absorbent material, such as cotton.
Middle layer of non-woven non-absorbent material, such as polypropylene.
Outer layer of non-absorbent material, such as polyester or polyester blend.
If purchasing a fabric mask from a store, check to make sure it meets national performance standards.
