Louisville is a tough place to live with asthma. The Asthma and Allergy Foundation of America named Louisville one of the top 20 "Most Challenging" cities to live in with asthma, and the #1 "Spring Allergy Capital" in the US in 2014.


In 2012, the City of Louisville partnered with Propeller Health and local funders to give 300 local residents a Propeller sensor that fit on top of their asthma inhaler. People in the program saw improved asthma outcomes after tracking their asthma for a year.


We are expanding this program to two thousand Jefferson County residents with asthma. Our goal is to continue to improve residents' daily lives, avoid costly ED visits and hospitalizations, and help city leaders make policy decisions.

Program and Partners

AIR Louisville is the first-of-its-kind data-driven collaboration among public, private and philanthropic organizations to use digital health technology to improve asthma. Propeller Health and the Institute for Healthy Air, Water and Soil are leading the program with support from the City of Louisville, the Mayor's office and the Louisville Metro Department of Public Health and Wellness.

In addition to local Louisville residents, a coalition of seven employers, three healthcare providers, a health plan and three advocacy groups have committed to enrolling patients, members, dependents, and employees. The program includes local employers Brown-Forman, Humana, Kindred Healthcare, Metro Louisville employees, Papa John’s, Seven Counties, WHAS11, healthcare providers including Family Allergy & Asthma, JenCare, and University of Louisville Pediatrics, and Passport Health Plan.

The American Lung Association of the Midland States, the Asthma and Allergy Foundation of America and the Kentucky chapter of The Nature Conservancy are also supporting the program.
