(21,449 posts)I have wondered about it, too.
Another possibility is to double mask, combining a cloth mask with a disposable blue surgical mask. The surgical mask has 3 layers (ultra thin, but effective due to the type of materials), and can be adjusted snugly at the nose, but leaves gaps at the cheeks. A good cloth mask has at least 2 layers, and is adjustable at the nose and ear loops. They should have little sliding plastic adjusters on the loops to pull the cheeks tighter or looser.
Between the two, the disposable surgical mask seals best at the nose and the cloth mask, worn over the surgical one, seals at the cheeks. The multiple layers of different materials act as filters.
I have several Hanes 3 layer, 100% tightly woven cloth masks. They do not have adjusters at the ear loops, but they are small and leave no cheek gaps. Since they are smaller than surgical masks, I wear the surgical mask over the cotton one.
I also have a box of 3M N95 masks, model #9010.
