CDC uses terminology that distinguishes a facemask from a respirator, as you will see from following the first link (‘health workers’) on the page you linked.

> … patients should wear a facemask to contain secretions.

> Use respiratory protection (i.e., a respirator) that is at least as protective as a fit-tested NIOSH-certified disposable N95 filtering facepiece respirator before entry into the patient room or care area.
