The main difference between the 3M 1860S Healthcare Particulate Respirator and Surgical Mask, N95, Small, and the 1870 mask is their design and fit. The 1860S is a cup-shaped N95 respirator designed for smaller faces, while the 1870 is a flat-fold, tri-fold N95 respirator. Both offer similar filtration, but the 1870 may provide a more comfortable fit for some users.
