What is the most effective way to use a cloth face mask?

A cloth face mask should ideally be made out of multiple layers of a pre-washed tight-weave non-stretch cotton material.
The mask should cover both nose and mouth and fit snugly but comfortably. It should be breathable.
Cloth face masks should be laundered or washed routinely depending on frequency of use. Laundry detergent/soap and water are adequate to kill the virus, due to their ability to break apart the fat layer (lipid envelope) protecting the virus.
Avoid touching the eyes, nose, or mouth when removing the face mask and wash hands immediately after removing.
Cloth masks should not be worn by children under 2 years, have severe intellectual or respiratory impairment, or by those who are unable to remove the mask without assistance. Supervise children under 4 years of age when wearing a face mask. Masks should not be worn around the neck.
