It’s important to remember that a reusable cloth mask should be washed in hot water after each wearing. If it’s not going right into the laundry, store it in a disposable bag that you don’t re-use. Disposable masks are one-use only and should be properly disposed of after use. Be sure to wash your hands after handling a mask, you should treat it as potentially contaminated with virus. If you’d like us to launder your mask, be sure to remove any filter elements, then fold the mask in half, with outer surface facing inward, and put it in a ziplock bag.
