Store your mask
Please follow the CDC for the latest updates:
Store wet or dirty masks in a plastic bag
If your mask is wet or dirty from sweat, saliva, make-up, or other liquids or substances, keep it in a sealed plastic bag until you can wash it. Wash wet or dirty masks as soon as possible to prevent them from becoming moldy. Wet masks can be hard to breathe through and are less effective than dry masks.
Store masks that are not wet or dirty in a paper bag
You can store your mask temporarily to reuse later. Remove your mask correctly and wash your hands after touching a used mask. Keep it in a dry, breathable bag (like a paper or mesh fabric bag) to keep it clean between uses. When reusing your mask, keep the same side facing out.
If you are taking off your mask to eat or drink outside of your home, you can place it somewhere safe to keep it clean, such as your pocket, purse, or paper bag. Make sure to wash or sanitize your hands after removing your mask. After eating, put the mask back on with the same side facing out. Be sure to wash or sanitize your hands again after putting your mask back on.
