Yes, of course, but thanks to the ViralOff® protective layer it is not necessary to wash the mask very often as it reduces 99% of viruses on its own within two hours thanks to its self-cleaning technology. The mask practically sterilizes itself in two hours. For best performance and sustainability, wash less and only when needed. Do not, however, ever wash or disinfect the removable nanofilters as that would compromise their ability to block pollutants and other contaminants.
