It's up to the manufacturers and wholesalers how many they sell to the medical industry vs others. The general public are not the Borg, they don't act with uniformity of purpose. If you tell the public "Don't buy these respirators from the hardware store" and 70% listen, then the other 30% will still buy out all the stock because demand is much higher than supply right now. You can't solve the problem at consumer level.
