A study examining the effectiveness of portable HEPA filters in reducing ultrafine particles (UFPs) from aircraft and traffic sources in five schools near Sea-Tac International Airport. The research found that HEPA cleaners significantly reduced indoor UFP concentrations to one-half to one-tenth of outdoor levels. Atmosphere 2022: https://www.mdpi.com/2073-4433/13/10/1623

A University of Washington research team held an advisory group meeting in August 2022 to discuss ultrafine particle (UFP) pollution in urban areas near airports. The meeting covered topics including indoor air quality in schools affected by aircraft emissions, short-term health effects of UFPs, and plans for mobile air quality monitoring. The multidisciplinary team includes environmental health scientists, researchers, and public health experts examining how aviation-related pollution impacts surrounding communities.

A 2021 Washington State legislative funding request of $912,810, sponsored by Representatives Tina Orwall and Jesse Johnson, seeks to deploy HEPA portable air cleaners in 20 schools across SeaTac, Des Moines, Federal Way, Normandy Park, and Burien to reduce students' exposure to outdoor air pollution from traffic and wildfire smoke. The University of Washington's Department of Environmental and Occupational Health Sciences would lead the project, measuring indoor air quality improvements and student performance outcomes. The initiative builds on an ongoing 2021 pilot study monitoring air quality in five schools within the Highline and Federal Way School Districts.

In October 2020, the City of Burien considered joining Des Moines, Federal Way, Normandy Park, and SeaTac in funding a $62,500 University of Washington study examining how ultrafine particles from aircraft emissions penetrate school buildings near Sea-Tac Airport. The first phase of the study would assess the air filtration efficiency of five schools located north and south of the airport, while a proposed second phase ($250,000) would test interventions to improve indoor air quality and measure their impact on student health and academic performance. Each participating city was asked to contribute $12,500, with the City Manager recommending approval of an Interlocal Agreement to move the project forward.
