During times of increased demand for KN95 respirators, people may want to protect these devices from surface contamination to prolong their uses. The CDC recommends wearing a face shield over a KN95 mask to protect it against surface contamination. Wearing a disposable or cloth mask over a respirator is not recommended because it is not consistent with the conditions of the approval.

The use of a face covering as an outer barrier, a washable face shield, could extend the useful life of a KN95 by acting as a physical barrier to potentially infectious liquids and droplets, as well as block large particles. It is ideal to find a reliable PPE product supplier to buy a KN95 respirator mask, hand sanitizer, 3-ply mask, and many others.
