Title: Improving Residential Air Quality: Barriers to Adoption of Air Purifiers and Effects on Health and Well-Being (Pre-analysis plan)

Joint with Patrick Behrer and Bridget Hoffmann

We will conduct a randomised controlled trial with three groups, a control and two free air purifier trials of 10 and 90 days, with low- and middle-income households in Mexico City. First, we will use air quality monitors, wearable fitness trackers, smart outlets, and in-person surveys to measure residential air quality and estimate the impacts of air purification on health and well-being. Second, we will test interventions to address three potential key barriers to adoption of purifiers: experience, information, and cost. After the interventions, we will elicit all participants’ willingness to pay (WTP) for the purifier in an in-person survey. Later in the survey, we will provide households in the trials with personalised feedback on objectively-measured improvements in air quality and health relative to matched control participants to increase information and the salience of the air purifier’s benefits and elicit WTP a second time.
