N95 and KN95
N95 respirators and face masks are examples of personal protective equipment (PPE) that are used to protect the wearer from airborne particles and from liquid contaminating the face. The Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health (NIOSH) and Occupational Safety and Health Administration (OSHA) regulate N95 respirators. CEP also carries KN95 masks.
What is the Difference? In short, N95 masks are the US standards for respirator masks; KN95 masks are the Chinese standards for masks. These are the requirements that the US National Institute for Occupational Safety and Health requires manufacturers to meet in order to label their masks as N95s. Despite the long list of differences, the two masks are equivalent or nearly equivalent on the features that most people care about.
