Economic players in the Auvergne-Rhône-Alpes region, mobilize to produce a reusable protective mask to fight against Covid-19.

A group of economic players from the Auvergne-Rhône-Alpes region, comprising the CEA, large companies, SMEs, institutions and local authorities, under the coordination of the Grenoble-based VOC-COV collective, has been working since March 16 on the design and large-scale deployment of a reusable mask.

Called “OCOV®”, this mask developed and produced in record time, is economical, long-lasting and can be manufactured in large quantities. Reusable up to 100 times thanks to its five washable and interchangeable filters, its cost is very competitive. A pre-series of 5,000 units of this first version is now being manufactured. The production capacity target is 1 million masks per week during May, i.e. a production exceeding 5 million by the end of June (the equivalent of 500 million disposable masks today). 130,000 masks are already reserved today.

Unlike an FF (Face Filter) P1 or P2 type filter made of filter material only, “OCOV®” is an FM (Face Mask) P1 or P2 type mask that includes a flexible face piece that covers the nose, mouth and chin, as well as reusable and replaceable filters. The loss rate required by the FM standard is 5 times lower than the FF standard (<2% for FM and <8% for FF filters). The soft face piece conforms to the shape of the face and therefore minimizes the leakage rate compared to FFP1 or FFP2 filters or other washable masks. It ensures a good seal between the surrounding atmosphere and the user’s face (whether the skin is dry or wet and when moving the head).
