New study finds no evidence of educational benefits from installing air filters in classrooms A new study was performed of a set of Los Angeles schools and found no effects on test scores, comparing schools with and without newly-installed air filters. However, this was a small study, and even though it found null effects, it could still be worth exploring the idea of installing air filters in classrooms, given all that we believe about the bad effects of air pollution. We should not let this particular null study deter us from continuing to explore this possibility.
