COVID 19: It can help to prevent spread of virus. Fabric masks should be at least two ply and tightly woven. If you hold the mask up to light and can see through it - it is less likely to be helpful.

Two masks: Double masking with a surgical mask and a cloth mask is more effective. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
