/ HOW TO ADJUST MASK FOR BEST FIT
Put on the mask and bend the nose bridge fairly tight around nose and press ends of the bridge against your cheeks. The tighter the fit, the better. Next adjust the ear loops. You want the elastic snug to keep the mask tight against your face but not so tight it becomes uncomfortable on the back of your ears. Start by holding the silicone tensioning button* with one hand and pull the bottom tubular elastic snug, then pull the top tubular elastic snug. You may have to do this a couple of times to get the fit just right. Repeat on your other ear. Use a clip to tie the ear loops behind your head if you need extra tension or if you want to relieve pressure on your ears.
