Adds a layer of protection.
Adds an additional layer of protection, especially for cloth masks which are not recommended for use without a filter. Easily fits into any mask with a built-in pocket. Cheap enough to be disposed of after just one use. Or you can wash the mask with the filter inside to extend the life for an extra wear.
