Interventions

BEHAVIORALUsing air purifiers with high-efficiency particulate air (HEPA) and carbon filters

Participants in the intervention arm will receive active air purifiers, which will be installed in their bedroom and the room where they spend the most time at home. The devices will operate continuously for the entire intervention period.

BEHAVIORALUsing air purifiers with non-functional filtration system

Participants in the intervention arm will receive sham air purifiers, which will be installed in their bedroom and the room where they spend the most time at home. The devices will operate continuously for the entire intervention period.
