The AIRWISE group will use two PACs to filter indoor air and two optical PM2.5 sensors with lights that change color in real time according to AQI. In addition, automated outdoor air quality alerts are sent via text and email when outdoor AQI goes above 75 (mid-point of the Moderate AQI category). Outdoor air quality will be referenced from the Environmental Protection Agency or PurpleAir monitor nearest to the participant's home. Based on the indoor and outdoor AQI levels, participants will reference a decision matrix and educational materials to make informed decisions on improving indoor air quality. Education and behavioral strategies are delivered through multiple approaches, including visual aids, handouts, videos, and a magnet with the decision matrix that can be placed in an accessible location in the home.",[13],"Behavioral: Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education (AIRWISE)",{"label":15,"type":16,"description":17,"interventionNames":18},"PAC Control","ACTIVE_COMPARATOR","Participants randomized to the PAC Control group will use two PACs in their home without additional AIRWISE equipment\u002Feducation.

To reinforce cues to action, AIRWISE uses alerts from air quality sensors, prompting timely behavioral responses. Specifically, indoor and outdoor air quality alerts act as behavioral cues to promote active engagement and reference a decision matrix with specific recommendations based indoor and outdoor air quality. Recommendations on the decision matrix include simple strategies to reduce air pollution exposures, including increasing use and fan speed of portable air cleaners, opening or closing windows to change ventilation, and changing activities such as physical activity, cooking, and cleaning. This integrated approach promotes sustained behavior change by aligning with all key HBM constructs.",[9],null,{"type":6,"name":28,"description":29,"armGroupLabels":30,"otherNames":26},"Portable Air Cleaner (PAC) Control","Participants will use two PACs in their home according to manufacturer recommendations.
