Buff is now launching the newly developed Filter Mask, a particularly comfortable and reliable face mask that can be worn comfortably for longer thanks to its innovative design and material. The mask with replaceable filter system meets the performance requirements of the standard for surgical masks (DIN EN 14683) with 98 percent bacterial filtration efficiency and high breathability. Part of the proceeds from sales will go towards supporting UNICEF projects worldwide in the fight against COVID-19. The BFilter Mask is now available at www.buff.com and will soon be available in selected stores.
