|Even if you never before considered getting a home air purifier to filter out smoke, pollution, pollen or pet dander, the widening pandemic may have you pondering such a purchase now.
But could an air cleaner really help keep your family safer from the coronavirus?
Maybe, scientists say, but it depends on the type. Certain purifiers – those with HEPA filters – might indeed add an extra measure of safety, when used alongside the usual cleaning, masking and distancing routines.
“It’s a relatively easy way to get clean air in a place where people are in close contact,” says Joseph Gardner Allen, an associate professor of exposure assessment science who directs the Healthy Buildings program at the Harvard T.H. Chan School of Public Health.
