Cloth masks are not approved or regulated by any health agency and depending on the tightness of the weave, can be pretty useless to protect against viruses. Those with a tight weave are hard to breathe through.
That's why disposable hospital, lab or construction masks are always better. Get a N95, KN95, or, for a child's face, a child KF94. They are certified and regulated by their respective countries (the standards of which are just as high as in the US) and are much lighter and easier to breather in than cloth masks - and they're also SAFER.
You don't need to throw them away after each use, as long as they're not wet (which alters the inner lining). Just buy several packs, and rotate through them, laying the used ones in the sun for a few hours to kill germs (or a clean, dry place for several days). Throw them away when they get too dirty.
