SEATTLE (Oct. 26, 2021) – Today, the U.S. Environmental Protection Agency announced the winners of the Cleaner Indoor Air During Wildfires Challenge. Challenge winners receive prizes of up to $10,000 for their proposed innovative technologies that could be used in homes to clean indoor air during wildfire smoke events. Three of the five winning projects selected nationwide are here in the Pacific Northwest, where longer and more intense wildfire seasons frequently cause unhealthy and even hazardous air quality in many communities.
“The increasing intensity of wildfires is a major public health challenge,” said Dr. Wayne Cascio, Acting Principal Deputy Assistant Administrator for Science in EPA’s Office of Research and Development. “The innovative ideas proposed by the challenge winners can further our efforts to protect public health and keep indoor air as clean as possible during wildfires and other high air pollution events.”
Wildfires release many pollutants that worsen air quality in areas downwind. Particle pollution, specifically fine particulate matter (PM2.5 or particles smaller than 2.5 micrometers), is a significant component of wildfire smoke and a known health risk for people exposed to high amounts or prolonged concentrations. Wildfire smoke exposure is particularly hazardous for people with pre-existing health conditions, such as asthma or cardiovascular disease. Smoke can spread many miles during wildfires, impacting communities near and far. Recommended responses to reduce smoke exposures during wildfires include staying indoors with doors and windows closed, when possible.
Current indoor air cleaning technologies have multiple limitations that prevent their widespread use, including the cost of purchase, operation, and maintenance, as well as dependence on electrical power, which can be disrupted by wildfires or rolling blackouts. The challenge winners developed detailed written proposals for affordable approaches to keep indoor air as clean as possible during periods when outdoor PM2.5 concentrations are elevated, such as during wildfire smoke events. Winners from this first phase of the challenge will be invited to submit prototypes of their technologies for evaluation in the next challenge phase.
