In its guide to opening schools, the Centers for Disease Control and Prevention (CDC) recommends schools consider adding portable air purifier units with high efficiency particulate air (HEPA) filters to “enhance air cleaning wherever possible.” The CDC’s FAQ on ventilation notes, “Portable HEPA filtration units that combine a HEPA filter with a powered fan system are a preferred option for auxiliary air cleaning.” 

An investigation by The Classic has found that, though it has told the public that two “HEPA Purifiers” will be in each classroom this fall, the New York City Department of Education (DOE) will be providing devices (Intellipure compact air purifiers) that do not match that description. The DOE has repeatedly referred to the Intellipure units as “HEPA purifiers” on its website, in a “DOE Homecoming Health and Safety Guide,” and in statements to The Classic. Multiple experts have told The Classic that to be a “HEPA Purifier” the units should have within them an actual HEPA filter, but they do not...
