How to get the best protection from a face mask:
1 Wash your hands with soap and water before you put on the mask and after removing your mask.
2 If your mask has ties, secure the upper ties first around our head.
Then pull the mask by the lower ties over your mouth and chin and secure it around the nape of your neck. If your mask has ear loops, then hold the mask from the ear loops while putting on or taking off.
3 When removing: start removing the mask from behind (do not touch the front of the mask)
4 Avoid touching your mask when using it and assume there could be virus on both sides of the mask.
If you do touch it, wash your hands immediately afterwards.
5 Wash your re-usable mask every time you remove it (60°C in the washing machine) or put the mask somewhere isolated until it can be washed.
6 Make sure you wear a clean mask each time you need to put one on.
