Context of use of consumer masks of category 1 filtration > 90% filtration

These masks are designed to protect against the projection of contaminated droplets. They are suitable for protection against COVID19. They are however reserved for Non-Sanitary Use (UNS1) in a professional context.

The health crisis linked to VIDOC19 has led to the implementation of certain measures such as the national containment in force since 17 March 2020, the reorganisation of work and barrier gestures. The use of UNS 1 filtration masks > 90% is part of the application of these safety measures.

Look out! Category 1 "UNS 1" barrier masks do not provide adequate protection for healthcare workers in contact with patients with IDVOC19.

This equipment is not considered a medical device within the meaning of EU Regulation 2017/745, also known as "surgical masks". UNS 1 filtration > 90% masks should also not be confused with personal protective equipment within the meaning of Regulation EU/2016/425, known as "FFP2 type filter masks".
