N95 masks are considered the foremost effective face covering and may catch up to 95% of particles. But they are not made to be sterilized and reused. But health care workers have had to reuse them anyway thanks to shortages of the masks and other PPE, like scrubs and gloves. Physicians have had to reuse potentially contaminated gear, which could expose them or their patients to coronavirus. it is the alternative to not using protection in the least , albeit reusing PPE poses some risk. It's a risk researchers don't need health care workers to require . Peter Tsai, the person who invented the N95 mask's filtering fabric, has begin of retirement to check sterilization methods. a gaggle of Duke University researchers developed their own method of decontamination in March using peroxide .

The Duke team's biocontamination method takes hours to finish , requires equipment many hospitals do not have and may only be spent to twenty times for an equivalent mask. The MIT researchers said they knew they needed to make a more versatile process -- or product. "One of the key things we recognized early was that so as to assist meet the demand, we would have liked to actually restrict ourselves to methods that would scale," said Dr. Giovanni Traverso, an professor of engineering at MIT and a gastroenterologist at Brigham and Women's Hospital. The researchers used several different sterilization methods on iMASC, including running them through an autoclave (steam sterilizer), putting them in an oven, and soaking them in both bleach and isopropanol . The silicone material was undamaged after each test.The MIT team is functioning on a replacement version of the mask, which they'll test to ascertain if it can efficiently filter viral particles. within the meantime, hospital workers -- and other people who work on essential businesses and schools that decide to reopen -- are urging local, state and federal leaders to supply more PPE to guard their health.
