With a filtering capacity of more than 94% for FFP2 and more than 99% for FFP3, the new BLS 502 and BLS 503 masks are DPI without valves, CE certified according to European regulation 2016/425 and technical standard EN 149: 2001, able to protect users in the event of exposure to solid and/or liquid non-volatile particles (dust, fumes, mists) and to block the dispersion of viruses both incoming and outgoing. They are, in fact, sealed on the face and manufactured with a "welding” process, without seams and perforations on the fabric from which micro particles could pass, thus creating a barrier during exhaling, protecting the environment from the user of the mask. These masks are therefore ideal for use in the food & beverage and medical sectors, as well as in all work environments where contamination by the user must be avoided.
