Dr Sandhya Ramanathan’s Quick Tip: Improving the seal of a surgical mask

Improving the seal around you nose and mouth by tying a knot at the base of the ear loops and tucking in the pleats as I’ve demonstrated in this quick video, can significantly increase the filtration effectiveness of a disposable surgical mask (from 39% to 60%). This is especially helpful when your face is small and there are big gaps allowing air leaks on either side when wearing the mask. Every small improvement in the seal/ filtration of your mask helps mitigate risk and reduce the viral load you are exposed to.
