Installing air filters in classrooms has surprisingly large educational benefits
$1,000 can raise a class’s test scores by as much as cutting class size by a third.
Hasnain says:
I wonder if there has been follow up research here since this study was done since the results are quite staggering.
“The impact of the air filters is strikingly large given what a simple change we’re talking about. The school district didn’t reengineer the school buildings or make dramatic education reforms; they just installed $700 commercially available filters that you could plug into any room in the country. But it’s consistent with a growing literature on the cognitive impact of air pollution, which finds that everyone from chess players to baseball umpires to workers in a pear-packing factory suffer deteriorations in performance when the air is more polluted.
If Gilraine’s result holds up to further scrutiny, he will have identified what’s probably the single most cost-effective education policy intervention — one that should have particularly large benefits for low-income children.”
