Abstract

This paper proposes a face covering designed to effectively capture SARS-CoV-2 while maintaining comfort and breathability. The approach uses amorphous silica microspheres attached to cotton fibers to capture bioaerosols, including SARS-CoV-2. Testing demonstrated ~93% average filtration efficiency for aerosolized proteins and inactivated SARS-CoV-2 with minimal breathability impact.
