Why do we have to wear KN95 masks?

• Masks are effective in preventing the spread of covid-19.
• KN95 masks are snug around the nose and mouth, and offer high filtration.
• According to the Centers for Disease Control and Prevention (CDC), “well-fitting disposable surgical masks and KN95s offer even more protection,” against the virus compared to both loosely and finely woven cloth products, and “well-fitting NIOSH-approved respirators (including N95s) offer the highest level of protection.”

How can I take care of my KN95 masks and reuse them?

• Store your mask in a paper bag for a few days after initial use. For best results, place the paper bag in a sunny place.
• Wash your hands before touching your mask, and touch only the elastic part when you put it on and take it off.
• Do not wash your masks with water, alcohol, hydrogen peroxide, or other chemicals.
• When your mask gets soaked with water or other liquids, it’s time to throw it away.

Tips for finding a legitimate N95

• Look for the NIOSH marking on the N95. This means the mask is approved by the National Institute for Occupational Safety and Health (NIOSH).
• Your N95 should not have any FDA approval markings, which only appears if it is a surgical-grade mask.
• According to the CDC, NIOSH does not approve child respirators. However, there are legitimate children sized KN95 and KF94 masks.

Tips for finding a legitimate KN95

• Look for a mask stamped with GB2626-2019. This is the KN95 standard for masks made after July 1, 2021.
• KN95 masks stamped with GB2626-2006 are still legitimate to use, as long as the expiration date on the product’s label or packaging has not passed.

Signs you may have a fake mask:

• Packaging not fully sealed
• No expiration date listed on product’s label or packaging
• Quality issues (elastics break or detach easily, nose-bridge is crooked)
• Has decorative components like sequins
