• Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.
  • Cover mouth and nose with the mask and make sure there are no gaps between your face and the mask.
  • Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.
  • To remove the mask: remove it from behind (do not touch the front of the mask). If you are using an Airinum mask or another reusable mask wipe the filter with a tissue and place it in a storage pouch; clean hands with alcohol-based hand rub or soap and water.
