A study finds that masks made from cloth commonly found in the home can make highly effective masks, capturing between 80 and 99 per cent of … Health agencies reserve N99 and N95 masks for healthcare workers as they provide the best protection to frontliners. Another recent study also determined that N95 masks offered better protection than surgical masks. A new study published in the scientific journal ACS Nano found that homemade face masks that use a combination of tightly woven cotton and polyester-spandex chiffon or silk will provide a very effective filter for the aerosol particles that spread the COVID-19 virus. A preliminary analysis of 194 countries found that places where masks weren't recommended saw a 55 percent weekly increase in coronavirus deaths per capita after their first case was reported, compared with 7 percent in countries with cultures or guidelines supporting mask-wearing. WHO recommends that fabric masks have three layers: an inner layer that absorbs, a middle layer that filters, and an outer layer made from a nonabsorbent material like polyester. However, there is limited knowledge available on the performance of various commonly available fabrics used in cloth masks. Science has repeatedly proven that face masks can prevent the spread of coronavirus and therefore save lives. Even so, research has suggested that wearing masks improperly or sporadically could still reduce transmission. But not all masks confer equal levels of protection. In an editorial published Tuesday in the Journal of the American Medical Association, CDC Director Robert Redfield predicted that the universal adoption of face masks could bring the US's outbreak under control in as little as four weeks. In a recent paper that hasn't yet been peer-reviewed, researchers in the UK determined that "hybrid" masks – combining two layers of 600-thread-count cotton with another material like silk, chiffon, or flannel – filtered more than 80 percent of small particles (less than 300 nanometres) and more than 90 percent of larger particles (bigger than 300 nanometres). Scientists from the UK found that people wearing cotton masks have a 54% lower chance of infection compared to those who do not wear anything at all. These materials are not ideal to use, but they are better than a single layer of cotton. A 2013 study found that these masks are three times more effective than homemade face masks and are also recommended for healthcare workers. However, the World Health Organization and the CDC still recommend the general public without any underlying conditions to wear a fabric mask. Scarves and cotton T-shirts reduced infection risk by about 44 percent after 30 seconds of exposure to the coronavirus, the Journal of Hospital Infection study found.
