ubumasks are fashionable pollution masks that comes in a range of patterns and sizes, designed to international standards KN95/N95/FFP2/P2 to allow even more people gain access to clean and healthy air. It filters over 99% of pollution, gases, bacteria and viruses.Viruses usually travel on droplets of water, which are very large. ubumasks will block these particles.The protection against viruses depends on the particle size of the aerosols containing infectious viruses. The sizes of these virus-containing particles differ from just the naked virus diameter (0,02–0,03 µm) to the sizes of the carrier particles. According to a study of the influenza virus, the virus-containing particles vary largely in size and 5% of the particles where larger than 4 µm, 75.5% was 1–4 µm and 19.5% smaller 1 µm. In another study of FMDV, 65–71% of the virus-containing particles were over 6 µm in diameter, 19–24% was 3 - 6 µm and 10–11% were under 3 µm. ubumask is tested and certified for over 99% protection against particles down to the size of 0.1µm and because of this, the mask will protect you against virus-containing particles that are larger than 0.1µm. However, we cannot guarantee full safety and protection against viruses.For more information, you can read the USA Centers for Disease Control and Prevention guidelines on Coronavirus here: https://www.cdc.gov/coronavirus/2019-ncov/about/transmission.html“It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.”
