Following the ANSM opinion of March 25, 2020, revised on April 21: cleaning protocol for reusable masks)

• Machine wash the mask with detergent. Choose a washing program that includes at least 30 min at 60°C minimum. You can put it in the machine with your laundry
• Dry the entire mask (the inner layers must also be completely dry). To do this, you can: use a tumble dryer (making sure to clean the tumble dryer filters and wash your hands afterwards), use a hair dryer, or even dry your mask in the open air, on a clean and disinfected support.
• Steam iron your mask at 110°C. As soon as the mask is dry, store it in clean airtight packaging (plastic bag or freezer bag, for example...)
