The KF94 face mask provides protection and comfort. With 4 layers, these white, disposable, Korean-made masks filter at least 94% of PM1 airborne particles when worn properly. The KF94 folds open to provide the user with ample breathing space and features an adjustable aluminum nose piece that ensures a secure fit and helps minimize the fogging of glasses. These masks are certified by the Korean Food & Drug Administration and all materials are made in Korea. Masks are sold individually.
How do KF94 masks compare to N95 masks?
The functional differences between N95 and KF94 masks are minor. The KF94 is the Korean standard similar to the US N95 mask rating. Korean standards are closer to EU standards than US standards, however. Standards require N95 masks to be somewhat easier to breathe out of (“exhalation resistance”); Korean masks are required to test for “CO2 clearance,” which prevents CO2 from building up inside the mask. In contrast, N95 masks don’t have this requirement. Additionally, to be label certified, Korea requires the human fit-tests for the KF94, which the US does not require for the N95.
Note: Ear loops on this mask are not adjustable. This product is non-returnable.
