NON Certified / A BIY Protective Face Mask for the General Public

Certified face masks that protect against viruses are currently only available for system-relevant professionalss and are still in short supply. ordinary containment masks for the general public can protect surrounding people, but does not offer good protection against external infections for the wearing person.
Offering better protection to the general public without putting even greater pressure on the market for certified masks led us to develop a reusable "Build-It-Yourself" mask. It offers a level of protection comparable to that of a certified mask and is therefore an effective alternative to ordinary masks.
