Interventions

BEHAVIORAL

Air purifiers

The 10 dormitory rooms were randomized into two groups of 5 rooms each. One group used an air purifier placed in the center of the room for 48 hours corresponding to one weekend, followed by a 2-week washout period, and another 48 hours of using a sham air purifier under the same conditions. The other group simply reversed the order in which the real and sham air purifiers were used. All rooms used the same qualified air purifiers (model FAP04, 3M Filtrete), with the only difference being removal of the filter gauze in the sham purifiers. The air pollution auto-sensing feature of air purifiers was disabled in both groups. All participants and research staff were blinded to the group assignment. We requested all participants to stay in their dormitory room with the windows/doors closed throughout each 48-hour intervention period.
