    We produce respiratory protection at the Niedenstein site. The OP mask has been checked in a German laboratory according to EN 14683 Type II. Specially approved by the German Federal Institute for Drugs and Medical Devices. Our face mask passed the test according to the EN 14683: 2019-10 Type II standard on 19th June 2020 in a German laboratory. Basic information: BFE (bacterial filtration efficiency) = 99.97%, limit value 98%, pressure difference (breathing resistance) = average of 29 Pa/cm², limit value 40 Pa/cm². Microbiological purity = average of 8.8 CFU/g, limit value 30 CFU/g. Dimensions 17.5 cm x 9.5 cm. For our face masks, we therefore rely on a combination of different micro non-woven filter materials, which clean the air in a filter cascade and consequently allow a wide range of uses. The mask is made of three layers. The middle layer is made out of ultra-fine melt-blown material (virus and bacteria filter). We use a product from a prominent German manufacturer here.
