Study Summary

This trial tests if using HEPA filters can improve heart and metabolic health by reducing air pollution.

Who is the study for?
This trial is for people aged 65-84 living in Los Angeles County who are overweight (BMI ≥ 25 kg/m2 historically), non-smokers for at least a year, have Wi-Fi at home, and speak English or Spanish. It's not for those with active cancer treatment, plans to move soon, certain health conditions, homes unsuitable for air purifiers or already equipped with HEPA filters.Check my eligibility
What is being tested?
The study tests if using HEPA filters in the home can improve heart and metabolic health by reducing fine particle pollution indoors. Participants will be randomly assigned to use either a real HEPA filter or a fake one without knowing which they have.See study design
What are the potential side effects?
Since this trial involves the use of air filters rather than medication, there are no direct side effects from interventions like you would expect with drugs. However, changes in air quality could potentially affect respiratory symptoms.

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: HEPA first and shamExperimental Treatment2 Interventions
This group of participants will be assigned an intervention of HEPA filters with the capacity to reduce PM2.5 levels at their residence for 6 months. After 6-month wash-out period, will be assigned to sham filters for 6 months.
Group II: Sham first and HEPAPlacebo Group2 Interventions
This group of participants will be assigned an intervention of sham filters without the capacity to reduce PM2.5 levels at their residence for 6 months. After 6-month wash-out period, will be assigned to HEPA filters for 6 months.
