Study Summary
Alaska Native children experience a high burden of respiratory disease, especially those in the Yukon-Kuskokwim (YK) Delta. Studies have shown that things like wood stove use, poor ventilation, and indoor tobacco smoke exposure can lead to poor indoor air quality inside the children's homes. This leads to more frequent and more severe respiratory infections in children. In the Yukon-Kuskokwim (YK) Delta, it's common for homes to have exposure to woodstoves and tobacco use. Both of these activities affect indoor air quality in homes. We know that high efficiency particulate air (HEPA) purifiers can reduce particulate matter and make air quality better. One way that we measure air quality is through particulate matter (PM2.5). One of the few studies that looked at this in the YK Delta found that PM2.5 levels that were nearly twice as high as homes with woodstoves in other states. We believe it is important to reduce the PM2.5 in YK Delta homes. However, the few studies that looked at HEPA purifiers in rural Alaska did not include homes where smokers lived. We know that breathing air with PM2.5 harms the lungs. We also know that HEPA filters can reduce PM2.5, which can mean reducing cough and wheeze in people with chronic lung conditions. We want to learn how HEPA filters work in homes with woodstoves or where a smoker lives, as it's likely these homes may have more PM2.5 than other homes. We expect that using HEPA filters will make the indoor air better and will mean decreased respiratory symptoms. We plan to include 15 households with a child less than 5 years old in the family. Households that join will be asked to: * Set up study equipment in their homes. * Run the study equipment for 12 weeks and do a weekly report of child's respiratory symptoms by phone or text. * Return the air-quality monitor equipment to the study team and keep the HEPA filters.
