Effect of Indoor Air Quality Improvement on Health in Patients With Interstitial Lung Disease

100 participantsStarted 2026-03

Plain-language summary

Air pollution threatens the respiratory health of patients with interstitial lung disease (ILD). High-efficiency air purifiers, featuring easy operation and excellent particulate matter removal efficiency, have been shown in previous studies to potentially delay lung function deterioration and reduce acute exacerbation risk in respiratory disease patients. This randomized crossover study employs air purifiers to filter indoor gaseous pollutants, allergens, and other contaminants, aiming to alleviate respiratory irritation, improve daily life comfort, and enhance overall health status in ILD patients.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients diagnosed with interstitial lung disease (ILD). * Stable disease status, defined as no hospitalization due to acute exacerbation within the past month. Exclusion Criteria: * Patients with complications of severe organ failure (including heart, liver, or kidney failure), malignant tumors, or mental disorders. * A history of respiratory tract infection within the past two weeks.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
