Air Purifiers, Fans, and Filters: A COVID-19 Explainer for Schools

COVID-19 is surging in nearly every state, and public health experts are warning that colder temperatures and increased indoor activity will mean the virus is likely to remain an urgent threat for the foreseeable future.

At the same time, schools are grappling with the potentially devastating effects of learning loss, social isolation, and diminished access to vital offerings for millions of students who haven’t been in a physical classroom since March.

Faced with limited resources and uncertain prospects for relief from the federal government, schools are in desperate need of clear, definitive guidance for reopening buildings safely and maintaining in-person instruction over the long haul. Some teachers in Boston have been posting pictures of their classrooms on social media and asking for guidance on whether their schools’ mitigation efforts are sufficient. (Boston officials have since since closed school buildings due to a surge in COVID-19 cases.)
