Choosing and wearing the correct mask size is quite essential for protection and comfort. If the mask doesn’t fit properly, you are always at risk of being exposed to hazardous particles, viruses, dust, smoke, etc. While deciding the correct mask size for yourself, measure from your chin to the bridge of your nose. Your face mask should always fit to cover your face from the bridge of your nose to under your chin. Furthermore, it shouldn’t be too tight-fitting or too loose. Make sure that the earloops or straps are firmly in place and fits comfortably.
