This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether two types of home air quality devices—energy recovery ventilators and portable air cleaners—can help control asthma symptoms and improve overall health in children and adults with asthma. Researchers will install one of these devices (or a non-working comparison device) in your home for one year and track how well your asthma is controlled, your quality of life, sleep, and stress levels during that time. The study is designed so that neither you nor the research team will know whether you're getting a working device or a non-working one, to keep the results fair and unbiased.
Many people with asthma live in homes where indoor air quality is poor—with excess moisture, mold, dust, and other pollutants that trigger asthma attacks. This trial exists to see whether improving home air quality through ventilation and filtration can reduce these triggers and help people breathe better, especially in lower-income households where asthma is more common and harder to control.

You will participate in this study for two years total. During the first year, researchers will assess your home's air quality and your asthma health without installing any devices. Midway through, you'll be randomly assigned to receive one of four interventions: a working ventilation system, a working air cleaner, or one of two non-working versions of these devices (for comparison). Over the second year, researchers will visit your home to measure air quality and mold levels, and you'll complete monthly surveys about your asthma control, quality of life, sleep, and stress.
