Newly published research on indoor air quality from Colorado State University shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings, published in Science Advances, show that wildfire smoke can attach to home surfaces like carpet, drapes or counters – extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers. However, Professor Delphine Farmer said the research also shows that simple surface cleaning – like vacuuming, dusting or mopping – can reduce exposure and limit risk. The research illustrates the hidden and persistent health threats many in the Western U.S. are facing given the increase in wildfires over the last decade, she said.
