How to buy face masks, according to medical experts
The most effective design, according to the study, was a dual-layer heavyweight cotton mask with a thread count of 180 or more. A double-layer mask with a simple cotton outer layer and inner layer also performed well, said Segal. Poor performers in the study consisted of a single-layer mask or a double-layer mask of low-quality, lightweight cotton.
“Some of these cloth items being sold are focused only on the decorative or artistic aspect,” Segal said. “You need to think about the effectiveness and the public health aspect of it. We don’t want people to think just any material is enough and give them a false sense of security.”
Some masks also allow for the ability to insert an additional filter, like a high efficiency particulate air, or HEPA, filter.HEPA filters are designed to clear out at least 99.7 percent of particulates that are 0.3 microns or larger in size. For reference, a micron, or micrometer, is about one twenty-five thousandth of an inch and designated with an μm. That can add an additional layer of filtration, said Segal.
Additionally, consumers should also find a mask that can be easily washed and is comfortable, said Anna Davies, a research facilitator who previously worked in the Infectious Diseases department at the University of Cambridge. “If you can’t breathe through it very well, you’re not going to want to wear it very long and air takes the path of least resistance so it’ll just bypass the material and go out the sides,” she said. “The wearer shouldn’t be touching their mask once on, so ideally a soft fabric is good.”
While shopping for a face mask, here’s the bottom line: Comfort, washability and dual-filtration is key. But above all else, keep practicing social distancing, washing your hands and other precautions, no matter what type of mask you have on.
