Wildfires at the wildland–urban interface (WUI) have been increasing in frequency over recent decades due to increased human development and shifting climatic patterns.

Low-income families in dry regions, including the Southwestern United States, frequently cool their homes with evaporative ("swamp") coolers (ECs). While inexpensive and energy efficient compared to central air conditioners, ECs pull unfiltered outdoor into home, creating a health hazard occupants when wildfire smoke heat events coincide. A community-engaged research project reduce was conducted California's San Joaquin Valley of Spanish-speaking agricultural workers. total 88 study participants were asked about level satisfaction EC willingness pay for filtration. About 47% reported dissatisfaction EC, most reason being that it brings dust pollution. Participants highly satisfied cleaners filters offered them free-of-charge. However, analysis showed filtration solutions would not be adopted without significant subsidies; furthermore, an ongoing cost due need regularly replace filters. Short-term users are feasible implement may exposure during events. Such at low-or no-cost barriers adoption. Longer term include prioritizing exposed regions replacement cooling technologies provide clean air. Because disproportionately low-income homes, addressing intrusion through these devices is environmental justice issue.
