In general, masks are used by the general public and health care personnel to prevent the spread of infection or illness.
Face masks marketed to the general public for general non-medical purposes, such as use in construction and other industrial applications, are not medical devices. Face masks, when they are intended for a medical purpose such as source control (including uses related to COVID-19) and surgical masks are medical devices., as described in our policy for face masks and surgical masks that is in effect during the COVID-19 pandemic.
The best way to prevent illness is to avoid being exposed to this virus. However, as a reminder, the CDC always recommends everyday preventive actions, such as hand washing and maintaining at least 6 feet of social distancing, to help prevent the spread of respiratory diseases.
