A: The CDC offers a number of evidence guidelines about cloth face coverings. Here are a few hot tips:
- Be sure not to touch the outside of the mask when you put it on and take it off (hold it by the straps). And continue washing your hands regularly.
- Be sure to wash cloth masks between wears. A washing machine is fine.
- Multiple layers is better. A recent study indicates that a second layer of nylon (yes, hosiery) can help increase protection by keeping more particles out and helping hold the underlying mask in place.
