Social media users have been sharing an image online that explains the difference between the blue and white side of a medical mask. The claim incorrectly advises to have the colored side facing out if you are sick and the white side out if you are healthy.

One post reads: “While at the doctors office today, we were informed by a Nurse the proper way to use a medical mask... When using a medical mask you’re supposed to use as follows: Colored side out if you’re sick and do not want to spread your germs around. White side out (this is the filter part) for when you’re not sick and you want to stop germs from getting in... The Nurse said the entire doctors office never knew either, until the supplier sent them “proper directions” for them this past week! Hope this helps!”

The image does not give any information about the name of the nurse, the doctor’s office or the supplier. It also does not credit any health organization or office for these directions.
