Marie Jönsson has a few tips:
Wash your hands before putting the face mask on.
Always hold the ear straps, never the mask.
The outside is usually blue or green; the white side should be facing inwards towards your face.
The face mask should cover your nose, mouth and chin.
The slightly harder side should face upwards. It should be pressed over the nose so that the face mask is tight.
Straps that can be tied around the head are easier to adjust than ear straps. Then the face mask sits tightly around the face.
Do not touch the face mask while wearing it.
If the face mask gets wet from rain or snow or if you have coughed, sneezed or talked a lot, you need to change it.
Throw the face mask in the bin. Do not put it in your handbag or use it more than once.
Always wash or disinfect your hands when removing the face mask.
