Air Filters, Pollution, and Student Achievement

This paper by Michael Gilraine from New York University probes something I had already read before, pollution, even mild amounts, can be harmful to kids learning outcomes. 

In this case a discontinuity regression is applied to a environmental event in NY.

"This paper identifies the achievement impact of installing air filters in classrooms for the first time. I leverage a unique setting arising from the largest gas leak in U.S. history, whereby the offending gas company installed air filters in every classroom within five miles of the leak (but not beyond). Using a spatial regression discontinuity design, I find substantial improvements in student performance: air filters raised mathematics and English scores by 0.20σ. Natural gas was not detected inside schools, indicating that the filters improved air quality by removing common pollutants. On that basis, these results should apply more widely."

I guess the situation was very tough as the leaky gas could be harmful to the students. I am glad theindoor air quality systems were installed on time and surprised too as it improved students' performance. Every school faculty should start giving importance to Air Purifier Installation as pollution is everywhere. Kids have the maximum chance to fall sick due to pollution or any kind of leaky gas. So according to me, it's essential to install air filters in every school.
