Abstract

Le "masque" selon l'invention est un dispositif de protection des voies respiratoires contre les micro-poussières ou les bactéries et les virus dans la phase d'admission d'air, afin d'éviter d'être contaminé et de contaminer l'environnement extérieur en émettant de l'air ou des gouttelettes potentiellement infectées. Les caractéristiques principales sont le degré élevé d'étanchéité du filtre, l'interchangeabilité, la bonne gestion de l'hygiène, la portabilité avec moins d'effets nocifs sur la peau, un remplacement rapide et la possibilité de recycler le filtre avec une désinfection par polymère.
