Theoretical Background
TriMask is a water-repellent cloth mask with three layers. Different studies have shown that three-layered masks are more effective and safer than one- or two-layered masks (Bahl et al., 2020; Fischer et al., 2020; Sharma et al., 2021). Unlike the single- and double-layered masks where large droplets pass through and atomize into aerosols or tiny droplets, triple-layered masks can prevent big droplets from a sneeze or cough from being atomized into aerosols. Aside from preventing the atomization of droplets, the three layers of the mask can also block small particles from penetrating through mask pores (Connor, 2021). Both are necessary for the aerosols not to leak and linger in the air. As such, cloth masks can similarly perform as surgical masks, given that it contains three layers (University of Surrey, 2021). Therefore, three-layered cloth masks can be as effective as surgical masks in lessening the transmission of infectious diseases like COVID-19. Although additional layers imp...
