HEPA air cleaner
Participants in the intervention group received two HEPA air cleaners per household. They were informed to place the HEPA air cleaners in the child's bedroom and the living room. Field staff provided and discuss how to use the air cleaner which promoted continuous operation of both air cleaners, keeping the child's bedroom door closed, and selected the highest fan speed. Typical use of the HEPA cleaners were questioned during the mid-study and final visits.
