3M instituted new packaging for the 2200434-MASK RESPIRATOR N95 REGULAR 3M#1860 and 4000142-MASK RESPIRATOR N95 SMALL 3M#1860S. The new packaging does not note that the product is “Regular” size. It only references the product number, 1860. The small size (1860S) does state “Small” on the new package.
- If you were fit tested for a Regular size you should wear the 1860
- If you were fit tested for a Small size you should wear the 1860S
