Today I will show how to sew a face mask with my own hands. Article 3 is the most common option. Two of them with a special pocket for replaceable filters. Reusable masks, they should be washed with soap or detergent, and then steamed with an iron or steam generator. Recommended materials: cotton, linen, gauze. I must say right away that such masks will not save you from viruses. They are effective only in combination with other methods of prevention. The World Health Organization does not recommend the use of cotton or gauze fabric masks as a means of protection against coronavirus infection. Masks should be worn by those who have symptoms of the disease so as not to infect other people. They are also suitable for dusty work in the house and for repairs. Remember to change medical / face masks every 2-3 hours.
