king county air ventilation
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. -
2021-05-01Healthy schools; A school based air quality intervention
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. -

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. -
2020-10-19Funding of Phase I of a University of Washington study in partnership with the cities of Des Moines, Federal Way, Normandy Park, and SeaTac — School resilience to air pollution
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. -

Relative sizes of various allergens
Diagram comparing the sizes of common airborne particles including human hair (50–70 microns), pollen (30–50 microns), ragweed (17–23 microns), dust mite (10 microns), and a 1-micron reference marker. The illustration uses scaled circles to visually represent relative particle sizes, relevant to air quality and filtration contexts. -
