3M Respirators - Half Mask

Half mask respirator facepieces from 3M. While a few come pre-assembled with cartridges, most are basic facepieces only, and will need filters and cartridges, which are ordered separately. With the Assemblies page, we have grouped mask and filter combinations by application. Questions about your specific application may be emailed to us.

Mask Sizing
Mask sizes are not quantified with measurements. Most, 80% plus, use medium. People with noticeably small or large faces use those sizes. That is a woman with a petite build and facial features would use small. Usually men with large faces, or prominent noses use the large. Unfortunately, this is how it goes. Fit testing is the only sure way to tell.
