Comparison of Mask Standards, Ratings, and Filtration 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.
