Case of 2000 Medical Grade Type IIR Face Mask Premium Quality

The Type IIR is the only mask category that is certified by the WHO (World Health Organization) for use in a close clinical environment. This is due to its fluid resistant properties, which is used specifically for close-proximity environments like dentists and care homes. The ‘R’ simply refers to an extra layer or ply that is able to prevent fluids from getting through, making it the only 4-ply mask in this category.
