Yes, Cambridge Masks are reusable and washable by handwash method only.
Handwashing the mask will remove dirt, make-up and surface dust. Our PRO mask inner filters are treated with silver which enhances the anti-viral properties of the technology used, so excessively washing the mask is not necessary.
However, the washing process will not extend the life of the filters. Each mask will need to be replaced after extended use to ensure proper filtration, preventing a build of particles within the filter.
