2020-01-01Air filters, pollution and student achievement
★A study by NYU economist Michael Gilraine found that installing air filters in classrooms led to a 0.20 standard deviation improvement in math and English test scores, using a natural experiment from the 2015-2016 Aliso Canyon gas leak in Los Angeles. The gas company installed air filters in all schools within five miles of the leak, allowing researchers to compare student achievement between schools that received filters and those that did not. The findings suggest that air filtration is a cost-effective way to boost student achievement by reducing exposure to common indoor air pollutants. -

Air purifiers
Should you get an air purifier? If you live near the flight path, the answer is ‘Yes’. Not only because of the aviation emissions, but also because of roadway emissions, the increasing prevalence of wildfires, and, if you have a Port Package, the increased risk of indoor mold.

2021-01-01Healthy Air, Healthy Schools study executive summary
A 2021 University of Washington study found that ultrafine air pollution particles from road and aircraft traffic near Seattle-Tacoma International Airport were infiltrating nearby school classrooms, with indoor levels reaching roughly half of outdoor concentrations before any intervention. Installing portable HEPA air purifiers reduced classroom ultrafine particle levels to about one-tenth of outdoor levels, cutting overall particle concentrations by an estimated 70%. A follow-up Phase 2 study is now underway in 30 Washington schools to examine longer-term air quality improvements and their effects on student health and academic performance. -

Airproofing: Piloting a Strategy for Improving Air Health in East Boston
This presentation outlines the 'Airproofing' pilot project aimed at improving air quality for residents of East Boston, a neighborhood heavily impacted by pollution from nearby Logan Airport. The project, a collaboration between Air Partners, Olin College of Engineering, Aerodyne Research, and community organizations, examines the problem of airport-related air pollution, explores protective solutions for homes and buildings, and describes testing methods and resource needs. While focused on East Boston, the initiative offers a potential model for addressing aviation-related air quality burdens in other airport-adjacent communities.
