1/4 - “Most home fabrics substantially block droplets, even as a single layer. With two layers, blocking performance can reach that of surgical mask without significantly compromising breathability...” medrxiv.org/content/10.110…
2/4 - “...Home fabrics are hydrophilic to varying degrees, and hence soak water. In contrast, medical masks are hydrophobic, and tend to repel water. Incoming droplets are thus soaked and “held back” by home fabrics, which might offer an advantage of home- made cloth masks.”
3/4 - “Overall, this study suggests that most double-layered cloth face coverings may help reduce droplet transmission of respiratory infections.”
4/4 - “During pandemics and mask shortages, home-made mask can be effective against transmission of infection through droplets. Mask wearing by all individuals, supported by proper education and training of mask making and appropriate usage, can be an effective strategy.”
