Face Fitting Of Mask Matters More Than Its Material: Cambridge Study
N95 mask's proper fitting is much more potent in providing protection against airborne particles than its material, suggested a study by the Cambridge University. Arguing over lack of understanding, the study revealed about the high failure rate of fit-check routines of such products. Moreover, it said a poorly-fitted mask is equal to a surgical or cloth mask. Advocating N95 masks as better ones, the researchers mentioned various significant facial features which matter in the best-fitting.
