The Centers for Disease Control and Prevention (CDC) created a technical guidance document titled “Evidence on the Use of Indoor Air Filtration as an Intervention for Wildfire Smoke Pollutant Exposure.” According to the CDC, the document summarizes the available peer-reviewed literature about the effectiveness of air filtration as an intervention to decrease exposure to wildfire smoke and protect health when sheltering indoors. It describes the different types of air filtering technology and metrics for measuring air quality and summarizes the literature on their effectiveness in protecting against the harmful air pollutants in wildfire smoke.
