Last year’s hot kitchen appliance is trendy again — this time, for being a virus killer. A recent study showed that electric multicookers — often dubbed Crock-Pots, slow cookers or Instant Pots — can decontaminate N95 masks. In the report published last month in the journal Environmental Science & Technology Letters, researchers from the University of Illinois, Urbana-Champaign discovered the electric multicooker is capable of decontaminating N95 respirators without chemicals and without compromising the equipment’s filtration or fit.
