About the study

The goal of this clinical trial is to learn if adding Air Quality Index (AQI) information to asthma action plans works to improve asthma outcomes in children. It will also learn about children with asthma who report being more sensitive to outdoor air pollution. The main questions it aims to answer are:

* Does adding either information about the EPA-AQI or commercial AQI improve asthma outcomes over time? * Are there changes in nasal gene expression in children with asthma who report they are more sensitive to outdoor air pollution?

Researchers will compare EPA-AQI and the commercial-AQI groups to a control group to either AQI works to improve asthma.

Participants will:

* Receive standardized outdoor air pollution education and an asthma action plan * Provide nose and blood specimens * Have visits every 4 weeks for 48 weeks, 10 will be conducted by telephone calls and 3 visits will be in person.
