Do you have an innovative idea for an effective, low-cost technology or approach to clean indoor air?
EPA and its federal, state, local and tribal partners announce a Challenge competition to encourage the development of effective, low-cost technologies to reduce indoor PM2.5 concentrations and protect public health. Applicants can submit designs for an innovative technology, approach, or technology combination. Winning submissions will receive prizes of up to $10,000. 

Attend the webinar to find out how you can participate in the Challenge.

The Challenge is now open, and proposals will be accepted through May 17th, 2021.
