WASHING: This fabric has been pre-washed and shrunk but we recommend washing before first use. Cloth masks should be washed often, especially after each use. Hand or machine wash with warm water and mild detergent, dry completely in a hot drier.
For masks with vinyl accents: do not dry clean. Wash and dry your mask inside-out. Use cold or warm water for the wash (not over 178 degrees F) and a mild detergent. Dry on a low/tumble setting or hang to dry. Do not iron.
You can tie the ends of your string together and place your mask(s) in a pillow case tied shut when washing so the string doesn't get all caught in your machine. Store clean mask in a clean container or bag.
FILTERS: What can you use as a filter? Google is your friend for this one. We've seen many different materials suggested from paper towel to coffee filters. Be safe and choose one that is right for you.
STRING: You can remove the string and replace it if you wish! You could even cut it and make smaller ties to slip around your ears if that's what you prefer. If your string accidentally comes out, don't panic! You can secure a safety pin to one end of the string and feed it back through the holes.
