Using a flat mask
Look for masks with pleats or folds. They allow the mask to expand in front of your mouth and nose when you breathe. This means you breathe through the mask, rather than pushing air out through the sides of it. Masks that are completely flat on the front are less effective because they might force air out and around your mask, rather than through it.
