Can Japanese Pitta Masks Protect Against Coronavirus

The Pitta masks claim to be 99% effective at filtering out pollen and dust particles, which range from 5-100 microns in size. The Pitta mask might be great at capturing pollen, but for viruses such as the coronavirus and flu, the Pitta mask doesnt cut it. 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.
