Surgical masks are recommended by the World Health Organization for personal protection against disease transmission. However, most of the surgical masks on the market are disposable and cannot be self-sterilized for reuse. Thus, when confronting the global public health crisis, severe pollution due to disposable masks is inevitable. In this paper, a novel low-cost filter mask with excellent breathability is reported to replace the filters’ oil derivatives through an ecologically correct filter with properties sustainably optimized on a pre-industrial scale (roll-to-roll). A roll of common paper was passed through a vacuum chamber and deposited by CVD. Hydrophobicity and permeation were measured through contact angle, SEM and AFM. The droplets do not penetrate the filter for a minimum of two hours. Moreover, the filters proved to be efficient in antimicrobial and breathability tests.
