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.

Infographic by Mark Nowlin for The Seattle Times, sourced from the Centers for Disease Control and Prevention, illustrating how various ventilation methods (no ventilation, open window, portable HEPA air filter, HVAC system) reduce airborne particles that may contain coronavirus. Data shows particle reduction percentages at end of a 4-hour visit and 1 hour later for six ventilation scenarios.
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. So many choices… However, the question of

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.
