Working in the lab, hospital or construction sites exposes you to different particles in the air that can be harmful. Use this respiratory mask from 3M to keep yourself safe from all elements whether they are dust or microbial, and continue breathing fresh air.

With the help of these three layers, this mask is able to keep out even those particles that are as small as 0.3 micron to supply you with breathable air.  Snug Fit Manufactured in a cup shape, this mask has an aluminium nose clip and elastic bands that let you wear it comfortably. Easy Storage You can easily fold this mask when you are not using it and store it in your apron pocket.
