Précimask®: Air Filtration for Mask Protection
This context boosted a consortium of French companies, led by Pracartis Group and with the participation of Saint-Gobain Performance Ceramics Refractories, to develop a revolutionary solution for reusable face masks: the Precimask®.
Its main differentiating feature lies in the use of cleanable and compact ceramic filters, which can achieve an excellent trade-off between retention efficiency and breathability. The filters can provide a filtration efficiency equivalent to surgical masks (>95% retention of bacteria-inoculated aerosols of 3 µm, ref. EN 14683 AC), with an enhanced tightness to ensure a reliable and high level protection.
The Precimask® has other interesting features, such as translucency and the use of biocompatible silicone to ensure maximum comfort and durability. The tight adjustment to the wearer’s face ensures an optimized protection against harmful microorganisms transmitted by respiratory droplets such as the ones produced during speaking, coughing or sneezing.
This major technological breakthrough is a great example of how Saint-Gobain Performance Ceramics Refractories can offer its extensive knowledge in ceramic materials science to partner with its customers in the development of more sustainable solutions that can make the world a better home.
