As the Omicron variant of COVID-19 continues to infect people around the world, figuring out the proper masks to keep you and your family safe has become more and more difficult. From N95, KN95, and now KF94, it can sometimes feel hard to decipher which one provides the best protection. That said, you may want to learn the differences between these preventative face coverings as you shop. 

Last year, we highlighted the difference between the best N95 and KN95 masks, so this article will focus squarely on the similarities and differences between KN95 and KF94 masks. Read on to learn more.

KN95 Masks vs. KF94 Masks: Similarities and Differences

Much like N95s, both KN95 and KF94 masks feature high levels of filtration, helping to keep unwanted viruses and particles from entering your nose and mouth. In short, KN95 masks are the Chinese equivalent of N95 masks and KF94 masks are the South Korean equivalent. The difference between them is simply in how they’re certified.

The “KF” in KF94 actually stands for “Korean filter,” while the “94” indicates a 94 percent filtration efficacy, making it closely similar to the KN95 mask, which offers 95 percent filtration efficacy. Although the KN95 provides one additional percentage of coverage, when sealed properly against the face, both the KN95 and KF94 are very efficient at preventing particles from entering your nose and mouth with a study from the NIH suggesting  KF94s are just as effective at protecting against COVID. KF94s are also typically made with four layers as opposed to three, providing an added layer of protection over the mouth and nose.

In terms of overall design, most KF94s come with side flaps, which mold to the contour of your face, and a nose bridge that adjusts to fit snugly. This gives it a fit that is both breathable and protective, making it a viable option when compared to KN95 and N95 masks. 

No matter which type of mask you choose, you’ll want to be sure you’re purchasing your face covering from a reputable company. Throughout the pandemic, news outlets such as The New York Times have cited counterfeit masks as a growing concern. When interviewed by NPR Sonali Advani, an assistant professor of medicine at Duke University shared, “Not all KF94 masks are made in Korea — many are manufactured in China — [but] KF94s manufactured in Korea may be less prone to counterfeiting.”

Given that, we’ve been careful to source products made in Korea with reputable reviews and recommendations. Take a look at some of the best KF94 and KN95 masks you can purchase online.
