A face mask helps you to protect yourself against dust, dirt and the possible transfer of bacteria and viruses. Wearing a cloth face covering can also be useful to avoid infecting other people when you may be a carrier of a bacteria or virus. The inner layer of the non-medical face mask is made of cotton for extra comfort while the outside is made of 100% polyester. The reusable face masks have comfortable elastic straps, and can be washed up to 60°C. We do not recommend using fabric softeners. The masks can be tumble dried on a delicate program.
