Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study (n=20) is a prospective evaluation of the implementation of an indoor air pollution intervention among adults 55 years of age or older. The intervention, called Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education (AIRWISE), is focused on improving indoor air quality through air filtration, education, and behavioral recommendations. All participants will receive the AIRWISE intervention with the objective of evaluating acceptance and use of the individual intervention components. This implementation study will inform the submission of a larger NIH proposal for a randomized trial. The central study hypothesis is that an intervention program with educational strategies and visual behavioral cues will increase knowledge and awareness of air pollution exposures among the participants and lead to improved intervention compliance.

Intervention Type OTHER

AIRWISE (Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education) utilizes personal air cleaners (PACs) to filter indoor air, while enhanced aspects focus on improving compliance to PAC use. Key components include low-cost sensors (PurpleAir, Inc, USA) that change color according to air quality index (AQI) and behavioral recommendations that correspond to varying AQI levels.
