Summary
A comprehensive study led by University of Colorado Anschutz Medical Campus and NIOSH/CDC researchers analyzed nearly 700 studies from 1929-2024 on air cleaning technologies like HEPA filters and UV systems. The research, published in Annals of Internal Medicine, found significant gaps in evidence for technologies claiming to prevent respiratory infections like COVID-19 and flu. Most technologies haven't been tested on people, and their potential risks remain poorly understood despite widespread claims about their effectiveness.
