Summary

This study seeks to reduce exposure to asthmagens in the homes of a community of Latino children residing in an area of intense agricultural production in Eastern Washington by testing the effectiveness of an intervention (high efficiency particulate air filter- HEPA portable room air cleaners) plus asthma education to reduce indoor measures of particulate matter, ammonia, improve clinically relevant measures of asthma health, and reduce biomarkers of inflammation.

Conditions

  • Asthma in Children

Interventions

DEVICE

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.
