New research on masks: doubling up cuts virus transmission by 96.5%

More layers equal more protection if your masks fit snugly against your face, according to new research published by the Centers for Disease Control and Prevention (CDC).

We know the virus that causes COVID-19 spreads through respiratory droplets. Masks help stop droplets. The more you can keep your droplets in and others’ out, the better at stopping the spread of COVID-19.

Key tips are:

  • Double up on your masks—consider adding a disposable one under your cloth mask. The CDC does not recommend doubling up on disposable masks because they typically don’t fit snugly.
  • Choose masks that have a nose wire to better block droplet passage.
  • Make sure your masks fit tightly to your face. You can add a mask brace (available at, Amazon or other retailers) to enhance the fit.


  • The mask must cover your nose and mouth to be effective at protecting others and yourself.
  • Remove your mask using the ear loops and wash your hands immediately.
  • Regularly wash cloth masks.
  • Throw away disposable masks after using.

When to wear a mask:

Wear a mask when you are around others who don’t live with you and you can’t keep at least a six-foot distance.

It is now a federal requirement to wear a mask when traveling by air, rail or bus, and when on federal property. Check your state and local health departments for evolving safety protocols in your area.
