Fabric masks or face coverings are available in a large sort of materials and might be something you create reception or furnish a store. While research into the employment of material masks is ongoing, their efficacy depends on the categories of material used and therefore the number of layers. The World Health Organization suggests three layers made up of:
- Inner layer of absorbent like cotton
- Middle layer of non-woven material like polypropylene
- Outer layer of non-absorbent material, such as polyester or polyester blend
Regardless of the form of face covering you decide on, it must cover the nose, mouth and chin and be secured with elastic loops or ties.
