Two years after the coronavirus pandemic, as the infectivity of the Omicron variant increases, people abandon cloth masks and reach for more effective N95 and KN95 masks. Chicago alone distributes 1.5 million masks through ward offices, schools and community groups.
N95 and KN95 masks are treated as disposable gear in clinical practice, but with proper care, they can be reused for long periods of time in daily life. (The difference between N95 and KN95 is mainly a matter of where they are certified. N95 in the US and KN95 in China.)
Here are some tips from the city authorities:
— Put the mask in a dry paper bag and keep it clean between uses.
— Wash your hands before putting on or taking off the mask to minimize dirt.
— Do not wash the mask or try to disinfect it with alcohol.
The National Biotechnology Information Center I have additional suggestions:
— Obtain 3-4 N95 or KN95 masks, number or label them, and rotate them daily.
— You can boil the mask for 5 minutes, being careful not to boil the elastic straps. Do not stir the mask in water. It is recommended to air dry.
The mask has reached the end of its life when it is dirty or stretched until it no longer covers the nose or mouth. According to health authorities, a snug fit is the most important consideration.
In the public indoor environment of Illinois, mask obligations remain for everyone over the age of two, regardless of vaccination status.
