Join us on October 26 as we announce the winners of the Cleaner Indoor Air During Wildfires Challenge. Winners will share their innovative designs for low-cost solutions that quietly and safely reduce indoor fine particulate matter (PM2.5) during periods when outdoor PM2.5 concentrations are high.

EPA and its federal, state, local and tribal partners held a Challenge competition to encourage the development of detailed plans for novel, effective, low-cost technologies to reduce indoor PM2.5 concentrations and protect public health during wildfire smoke events.

Exposure to PM2.5, an air pollutant from wildfire smoke and other sources, can be harmful to
lung and heart health, especially for those with pre-existing health conditions.
