Brookaire Manufactured KN-Style Dust Mask - 50 Pack

(0) No Reviews yet
This mask is assembled from a synthetic composite filtration material. The filtration efficiency of particles sized 0.3 microns is 95%. The efficiency was “flat sheet” tested by the manufacturer in their laboratory. This testing was performed for the purpose of making air filters and is NOT NIOSH certifited for medical grade face masks.

This mask will provide a moderate degree of protection against sub-micron particles which may carry airborne viruses. The outer layer of this mask is durable and will stand up to normal work environments. The micro-fiber inner layer of the mask is soft and comfortable when in contact with the face. The plastic coated steel nosepiece is formed to the bridge of the nose to ensure a good seal to the face of the wearer. The heavy-duty elastic band is non-latex. 
To wear: put the elastic band over your head, above the ears, form the plastic noseband around the bridge of your nose. 
Ensure the mask contacts your face around the entire circumference. If gaps are present, try a samller size.
