Respirators and masks serve different purposes. The point of the masks is to prevent infected people from contaminating surfaces and other people by catching exhaled aerosols that might contain the virus. Respirators are mainly intended to filter inhaled air - they often use one-way valves to bypass the filter altogether when exhaling.
Why isn't anybody making/talking about cheap respirators with changeable filters?
Double sales, higher stocks. Maybe that's the goal?

Oh, ok.
