Official title
ASPIRE (Advancing Science Partnerships for Indoor Reductions of Smoke Exposures)-Health Tulare County
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this clinical trial is to compare indoor air quality and health in people exposed to air pollution, including possible exposure to wildfire smoke. The study will test the effect of using a do-it-yourself (DIY) air cleaner when air pollution is present to answer the following questions: * Do health outcomes differ between participants who use a DIY PAC and those who use a sham air cleaner? * How effective is the DIY air cleaner in reducing indoor concentrations of fine particles (PM2.5), and volatile organic compounds found in wildfire smoke? OR How effective is the DIY air cleaner in reducing indoor concentrations of fine and coarse particles (i.e., PM 10)? * What are barriers to use of a DIY air cleaner and what factors facilitate its use? Participants will be asked to do the following: * Participate in 5 home visits from study staff between July - October 2023 * Have an air quality sensor placed in the participant's bedroom for the whole study period * Have a small sensor attached to the main door of the participant's house to record when the door is open or closed (important for air quality inside) * Allow researchers to take air and dust samples in the participant's bedroom * Run a DIY air cleaner in the participant's bedroom for at least 6 nights while the participant sleeps * Complete 2 interviews * Allow study staff to collect 3 fingerstick blood samples * Allow study staff to collect 3 samples of fluid from inside the nose * Use the study air cleaner in the participant's bedroom during the study period The investigators will measure air quality in participating homes and measure health outcomes for participants. The investigators will compare outcomes of participants who use a DIY air cleaner with filters that work well to those of participants who use a DIY air cleaner with a placebo filter (one that does not work well to remove the air pollutants of concern). The goal of the study is to see if using the effective air cleaner leads to better health outcomes and indoor air quality.
