COVID-19 mask use: How to make your mask fit properly

The way your mask fits can help prevent you and others from being exposed to COVID-19.

Choose a mask made of multiple layers, including at least 2 layers of tightly woven fabric and a third middle layer of filter-type fabric.

Before touching your mask, wash your hands with soap and water for at least 20 seconds. If soap and water aren't available, use a hand sanitizer containing at least 60% alcohol.

Other ways to improve mask fit are as follows.
