型號「8210/8110」及「9210」則屬於工業用口罩，主要用於阻隔塵埃，雖然亦經過 NIOSH 認證，但沒有FDA認可，未必能有效阻隔飛沫。

3M™ Particulate Respirator 8210, N95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles. This respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging, or other dusty operations. This respirator can also help reduce inhalation exposures to certain airborne biological particles (examples: mold, Bacillus anthracis, Mycobacterium tuberculosis), but cannot eliminate the risk of contracting (感染) infection, illness, or disease.
