How can you tell if your N95 or KN95 mask is fake?

(WJW) — The Center for Disease Control and Prevention began recommending Americans wear high-quality masks, specifically KN95s and N95s, amid the omicron surge last week.

But with all the choices on where to buy them and which type, it can get confusing to determine which masks are the real deal.

The CDC reports that 60% of the KN95 masks (a version of N95 masks made in China) in the U.S. are fake, for example.

The most common pitfall scenarios, according to the CDC, occur because:

Below is some information to help you choose your masks wisely.

What are N95 and KN95 masks?

As outlined by the Cleveland Clinic, cloth masks don't do much to protect users from inhaling particles that carry the virus.

According to the CDC, tight-fitting masks like N95 and KN95 respirators are designed to protect the people wearing them from particles, including the virus that causes COVID-19. But, at the same time, they protect others from the wearer's respiratory droplets and particles.

Some respirators are tested to meet international health standards and are labeled to tell users what standard they meet. The most widely available respirators that meet international standards are KN95s, according to the CDC.

But others go a step further and also meet a specific U.S. standard that includes a quality requirement through the National Institute for Occupational Safety and Health (NIOSH). Those include the N95 respirators.

The CDC recommends that specially labeled "surgical" N95s be prioritized for health care workers.

"It's really best to find a mask that has been approved by a regulating body," said the Cleveland Clinic's Dr. Steven Gordon. "But the truth is that at the end of the day, any mask that fits closely to the face is better than a mask that doesn't."

How can you tell if your mask is a counterfeit?

The CDC warns that some counterfeit respirators are falsely marketed and sold as being NIOSH-approved. As a result, they may not be capable of providing appropriate respiratory protection, according to the CDC.

NIOSH-approved respirators, like N95 masks, will have an approval label on or within the packaging of the respirator. An abbreviated approval is also on the respirator.

KN95 masks are not approved by NIOSH, so legitimate KN95 masks should not include a NIOSH-approved stamp or claim.

Other signs that a respirator may be counterfeit, according to the CDC, include the following:
