Don't get confused between the N95, KN95 and KF94 masks: while all serve the same purpose of covering the nose and mouth and prevent COVID-19, each have a different filtering standard. The "KF" in KF94 stands for "Korean filter," as the disposable mask is made in South Korea, and the "94" refers to the mask's 94% filtration efficiency.
Its design also differs from KN95 masks, as it has a larger pocket in the front with an adjustable band.
KF94 masks can come in both child and adult sizes and are available to purchase in multipacks and a variety of colors on Amazon. Dr. Ashish Jha, dean of the Brown University School of Public Health, told the New York Times the KF94 mask is made of a similar material as the N95. The notable difference is the KF94 has ear loops instead of elastic bands.
KN95 masks are made in China and rated capture 95% of tiny particles, or about 0.3 micron particles. At the beginning of the pandemic in 2020, N95 masks were originally in high demand and often reserved for health care workers, but are now much easier and more available for purchase online or in home improvement stores such as Home Depot and Lowe's.
