The US Centers for Disease Control and Prevention has released instructions and visual tutorials on how to make cloth face coverings from common household materials.
The CDC recently released guidance recommending the use of cloth face coverings "in public settings where other social distancing measures are difficult to maintain, especially in areas of significant community based transmission."
Cloth face coverings, according to the CDC, can be homemade out of pieces of fabric, T-shirts, bandannas and coffee filters to slow down the spread of the virus, especially those that may be asymptomatic and capable of transmitting it to others despite experiencing no symptoms.
The CDC recommended any homemade cloth face coverings include multiple layers of fabric, be secured to the ears, and allow for breathing without restriction. The guidance recommends routinely cleaning coverings in a washing machine and that no child under the age of 2 should wear them.
