The name of the KN95 certified face mask relates to its effectiveness. Purar is derived from Pure Air and refers to the fact that the comfortable, lightweight and washable mask can filter more than 95 per cent of all particles with a diameter of 0.3 μm or more from the air we breathe. Its ergonomic design is characteristic; it prevents glasses from fogging and allows for comfortable adjustment to the shape of the face. With its comfortable neck strap, the face mask also offers safety for users of headphones and AirPods.
