Mar 15, 2020 · Single use masks (normally one layer, very thin) are typically only effective at capturing larger dust particles, but can do so fairly well. Surgical mask standards have higher requirements for capturing virus-sized (0.1 micron) particles, however they vary by region. Pollution masks (respirators) typically capture >90% of virus-sized particles.

Scientific Achievement Filtration efficiency for fabrics used in cloth masks as a function of aerosol particle size was determined. The highest performers were hybrid fabrics with high thread-count cotton and electrostatic layers such as silk or polyester chiffon.
