Air Queen Nanofiber Filter Mask

3D trifold design with adjustable nose piece provides a snug but comfortable fit. N95 filter and breathable structure allows for use in clinical and non-clinical settings. NIOSH N95 certification pending.

KF94 is the Korean standard for 94% effective particle filtration, the Korean equivalent to the US N95 mask rating. South Korea has been extremely efficient in their response to COVID-19. By conducting widespread testing, keeping close track of confirmed cases, and managing the distribution and use of certified masks, Korea has effectively contained the outbreak.

KF94 classified products are required to meet a lower inhalation resistance standard compared to the N95.  Additional tests required for KF94 standards include a CO2 clearance limit (prevents CO2 building up while wearing) and human fit-tests. These restrictions ensure KF94 certified products are breathable and ergonomic as well as effective. KF94 (like CE standards) also tests filtration performance with both salt and paraffin oil, unlike US certification agencies, which test with only salt particles.
