CA 2665394

Microwave energy may be used to disinfect used face masks, respirators and other items containing filtration media for respiration. A method of disinfecting is provided as well as filtration media having indicators to visually indicate when disinfection has occurred. The indicators may function based on temperature and steam generation during microwaving. Thermochromic materials may be used to indicate that a proper temperature has been reached.

Selon l'invention, l'énergie micro-onde peut être utilisée pour désinfecter des masques faciaux usagés, des respirateurs et d'autres objets contenant des matériaux filtrants pour la respiration. Un procédé de désinfection est proposé ainsi que des matériaux filtrants comportant des indicateurs afin d'indiquer visuellement le moment où la désinfection s'est produite. Les indicateurs peuvent fonctionner sur la base de la température et de la génération de vapeur lors d'un passage aux micro-ondes. Des matériaux thermochromiques peuvent être utilisés pour indiquer qu'une température correcte a été atteinte.
