Asthma Intervention With Residential Ventilation and Air Cleaner (AIRVAC) Study
This study, called AIRVAC, is looking at how well two types of home devices, Energy Recovery Ventilators (ERVs) and Portable Air Cleaners (PACs), can help people with asthma. ERVs bring in fresh air while saving energy, and PACs filter indoor air. The study wants to see if these devices can reduce indoor air pollution and mold, and improve asthma symptoms, lung function, quality of life, stress, and sleep for adults and children (ages 5 and up) with asthma who own homes in the Dallas-Fort Worth area. You cannot participate if anyone in your home smokes. The study aims to enroll 80 participants, but its current status is unclear.
- Study design
- This is a randomized, double-blind, placebo-controlled study with four groups, involving 80 participants (children and adults). Participants will receive either an active device or a sham (placebo) device.
- What's involved
- You would participate in a study with a 1-year observation period followed by a 1-year intervention period. Your lung function and asthma control will be measured at various times over 24 months.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your pulmonary function will be measured at 6, 18, and 24 months. Your asthma control will be monitored for 24 months.

What this trial measures
- Pulmonary Function (Spirometry)Baseline; 6 months; 18 months; 24 months
Pulmonary function will be assessed using an EasyOne Air spirometer. The primary parameters measured include Forced Expiratory Volume in 1 second (FEV₁), Forced Vital Capacity (FVC), and the FEV₁/FVC ratio.
- Asthma Control Test ScoreFrom enrollment to the end of intervention at 1 month (24 months in total)
Asthma Control Test (ACT) for adults and Childhood Asthma Control Test (C-ACT) for children every month throughout the 2-year study. ACT score range: 5-25; higher scores indicate better asthma control. C-ACT score range: 0-27; higher scores indicate better asthma control.
