No, some masks are designed with a breathing valve, the breathing valve is a one-way valve to help the wearer reduce the exhale resistance, the exhale when the positive pressure valve open, can be a smooth exhale, the inhalation of the negative pressure so that the valve closed, effective filtering of inhaled air.
Because expiration is not effectively blocked, viral and suspected infected persons cannot wear masks designed with breathing valves; at the same time, medical protective masks are prohibited from being designed with breathing valves, so all masks with breathing valves are not medical masks.
