KN95 is a Chinese respiratory standard (GB2626-2019) requiring ≥95% filtration efficiency against non-oily particles. This performance level is very similar to the US N95 standard (≥95%) and the European FFP2 standard (≥94%). The European FFP3 standard requires higher filtration (≥99%). While the core filtration efficiency goals are similar for KN95, N95, and FFP2, there can be minor differences in testing protocols and specific regulatory requirements.

These masks are designed as disposable respirators for limited use. They should be replaced if they become soiled, damaged, or if breathing becomes difficult. Reusing disposable respirators is generally not recommended as it can compromise fit and filtration effectiveness.

Ensure the mask fully covers your nose and mouth with no gaps. Place the head straps correctly (one upper, one lower). Press the adjustable nose clip firmly to conform to the shape of your nose bridge. Perform a user seal check: inhale and exhale sharply – the mask should slightly collapse inwards on inhalation and expand on exhalation without air leaking around the edges.

GB2626-2019 is the current Chinese mandatory national standard for respiratory protection – specifically covering non-powered air-purifying particle respirators. It outlines the technical requirements, testing methods, and markings for masks like the KN95, ensuring they meet specific performance criteria, including filtration efficiency (≥95% for KN95) and breathing resistance.

While KN95 masks offer high particle filtration (≥95%), they are certified under the GB2626 industrial standard, not typically as medical devices (e.g., like surgical masks certified to EN 14683 which focus on splash resistance). They primarily protect the *wearer* from inhaling particles. For specific medical or healthcare settings, consult relevant guidelines to ensure the appropriate type of certified PPE is used.
