Brief Summary
The goal of this clinical trial is to learn about whether indoor air quality will improve over time in homes where occupants receive personalized information about levels of health-relevant air pollutants that includes practical, budget-friendly, and culturally relevant recommendations on actions they can take to improve their home's air quality. The rationale for the investigators' approach is that a rigorous intervention study design will generate robust evidence on the value of the in-home environmental data. Participating homes in both the intervention and control groups will receive three, one-week Home Health Box deployments spaced six weeks apart. After each of the first two deployments, homes in the intervention group will receive a Home Health Report with personalized information about in-home levels of health-relevant air pollutants and cost-sensitive recommendations on actions occupants can take to improve their home's air quality. The investigators will (a) investigate whether and how air quality changes over time in control and intervention homes and (b) survey intervention households on the utility of the Home Health Reports.

Outcome Measures
Primary Outcomes (1)
In-Home Air Quality
In-home concentrations of fine particulate matter, nitrogen dioxide, and volatile organic compounds.
from eight to up to 24 weeks
Study Arms (2)
Intervention
EXPERIMENTALThe Home Health Report will provide quantitative information about health-relevant pollutants (fine particulate matter, carbon dioxide, nitrogen dioxide, and volatile organic compounds), their levels compared to health-based guidelines, their potential sources, as well as no- and low-cost actions occupants could take to improve indoor air quality. The Home Health Report will be designed to maximize utility to residents. Each Home Health Report will be provided after the corresponding Home Health Box deployment. The second Home Health Box deployment will occur after the household receiving their first Home Health Report. The third and final Home Health Box deployment will occur within one month of the household receiving their second Home Health Report.
Control
NO INTERVENTIONHouseholds in the control group will also receive three Home Health deployments spaced over several months, but will not receive Home Health Reports after the first and second deployments. At the close of their participation in the study, households in the control group will receive a comprehensive Home Health Report, including results from all three Home Health Box deployments and recommended actions occupants could take to improve their home air quality.
Interventions
The Home Health Report has been described in the intervention arm description.

- Time Frame
- Data will become available to researchers associated with the project via the collaborating institutions as the data are being collected and for up to three years beyond the end of the study period.
- Access Criteria
- Researchers will be eligible for access if they are members of the overall study team.
Our human subjects work will generate a comprehensive dataset that includes information on in home exposures, in-home activities, and home air quality in the form of quantitative, reference grade information on aerosol and gas constituents in indoor air. After de-identifying these data (including location data), we will publish these data in peer-reviewed journals. We will also generate subject response data from surveys and interviews. These data will be organized, assembled, and analyzed for publication in peer-reviewed journals. Standard restrictions would apply to the secondary research use of data involving human subjects, and these data would only be made available through a written agreement with the party requesting the data, after being deidentified.
