Summary
This pilot study tests whether giving N95 masks and indoor air cleaners to 20 older adults with COPD can reduce lung flare-ups during poor air quality from wildfires. Participants are Kaiser Permanente members aged 65+ who use oxygen. The study focuses on whether this approach is practical and acceptable, not yet on health outcomes.

What this could lead to
