- Wash with soap at night after one day’s wear, and best to be washed with warm/hot water
- If you would encounter many people during the day, it is recommended to wash the mask with boiled water or hot water with at least 60 degrees. You could simply sink the mask in the hot water for around 10 to 15 minutes, to ensure the kill of all virus
- If you would like to wear the same mask every day, you could choose to iron (several times) the mask right after wash, not to make the mask flat, but to ensure that the mask could be fully dried over night !

Although there is no sign on the mask for up & down, when you wear them, if you feel that your nose is too close to the inner layer while breathing, you could try to switch the up side down of the mask.
