Poor air quality is a pressing environmental health concern in many low-income countries, especially in South Asia, where stringent environmental laws coexist with weak regulatory institutions and inconsistent enforcement. In such a context, understanding the role of private defensive investments like air purifiers in households and workplaces is paramount. However, we know extremely little about the adoption, use, and impact of air purifiers. To fill this void, we will conduct a randomized control trial with households in Dhaka, Bangladesh. The project will answer four research questions: (i) What are the benefits of air purifier use? (ii) Does correcting misperceptions about air pollution severity increase the demand for and use of air purifiers? (iii) Does subsidizing electricity costs or altering the frequency of electricity compensation increase air purifier use? (iv) Do investments in air purifiers diminish households’ engagement in efforts to reduce ambient air pollution?
