THESE ARE THE BEST AND WORST MATERIALS FOR FACE MASKS

 While research has revealed masks work in decreasing the spread out of COVID-19, not all masks or mask products are equally effective, inning accordance with new research.

"WE KNEW THAT MASKS WORK, BUT WE WANTED TO KNOW HOW WELL AND COMPARE DIFFERENT MATERIALS' EFFECTS ON HEALTH OUTCOMES."

In a research study in the Journal of Medical facility Infection, scientists evaluated the ability of a variety of nontraditional mask products to protect an individual from infection after 30 secs and after 20 mins of direct exposure in an extremely polluted environment.

When the scientists contrasted wearing masks to wearing no protection throughout 20-minute and 30-second exposures to the infection, they found that infection dangers were decreased by 24-94% or by 44-99% depending upon the mask and direct exposure period. Risk decrease reduced as direct exposure period enhanced, they found.

MASKS FROM BEST TO WORST

"N99 masks, which are much more efficient at filtering system air-borne bits compared to N95 masks, are certainly among the best options for obstructing the infection, as they can decrease average risk by 94-99% for 20-minute and 30-second exposures, but they can be hard to find by, and there are ethical factors to consider such as leaving those available for clinical experts," says lead writer Amanda Wilson, an ecological health and wellness sciences doctoral prospect in the community, environment, and plan division in the Mel and Enid Zuckerman University of Public Health and wellness at the College of Arizona.

The next best options, inning accordance with the research, are N95 and medical masks and, perhaps remarkably, vacuum filterings system, which can be inserted right into filter pockets in cloth masks. The vacuum cleaner filterings system decreased infection risk by 83% for a 30-second direct exposure and 58% for a 20-minute direct exposure. Of the various other nontraditional products evaluated by the scientists, tea towels, cotton-blend fabrics, and antimicrobial pillowcases were the next best for protection.

Headscarfs, which decreased infection risk by 44% after 30 secs and 24% after 20 mins, and similarly effective cotton tee shirts are just slightly better compared to wearing no mask at all, they found.

"We understood that masks work, but we wanted to know how well and contrast various materials' impacts on health and wellness outcomes," says Wilson, that focuses on quantitative microbial risk evaluation.
