You probably know that N-95 masks are the most effective face coverings—and that they should be reserved for frontline workers. But do you know about the N-95’s sister, the KN95 mask? The few KN95 masks available on Amazon have been selling out quickly but are slowly being restocked. Here’s a rare chance to buy some. Read on...

What makes KN95 masks so effective?

KN95 masks are almost identical to N-95 masks. “The basic difference is regulatory,” says Dr. Kavita Patel, managing director of clinical transformation at The Brookings Institution’s Engelberg Center for Health Care Reform. “KN95 masks are approved by Chinese regulators, and in theory they are similar to N-95 masks, which are approved by the FDA but also likely to be manufactured in China. This means they keep out 95 percent of particles, which is essentially the highest filtration you can get.”

The KN95 mask’s interaction with the U.S. medical system has varied recently. When the pandemic first hit and N-95 masks and other medical-grade masks were in particularly short supply, the FDA granted an emergency use authorization for medical workers to use KN95 masks. Now, the FDA has removed its emergency use authorization for several manufacturers of KN95 masks after they failed to filter out up to 95 percent of particles—a hallmark of N-95 masks. However, others are still authorized for use.

Many healthcare professionals use KN95 masks, as there is still a shortage of N-95 masks for clinic-based doctors. “The sense is that these are better than the common surgical mask, which filters anywhere from 40 to 75 percent of particulates, depending on type and fit,” says Dr. Patel. “Compare this to cloth masks, which optimally can filter about 60 percent of particles.”

That said, while regular three-ply disposable masks or cloth masks should do the job when you’re social distancing at least six feet away, KN95 masks offer more protection in riskier situations, like on public transportation or when flying.

High-quality KN95 masks prevent the spread of coronavirus as effectively as N-95 masks. “If your source for a KN95 mask is reliable, you should be fine to buy them,” Dr. William Schaffner, an infectious disease specialist and professor at the Vanderbilt University School of Medicine, tells Yahoo Life. “They’re comparable to the N-95 masks that we use.”

I will be purchasing more.”
