100 free portable air-quality sensors available for residents

City of Sacramento residents and businesses now can apply to receive a free portable Purple Air sensor as part of a pilot project aimed at enhancing air quality data in high-need, underserved neighborhoods. Schools located anywhere within the city of Sacramento also are eligible.

Supplies are prioritized for high-need areas in the City of Sacramento including North Sacramento, South Sacramento and outside of Downtown/Central City. Recipients will be selected based on geography and other criteria to ensure equitable distribution among neighborhoods.

The application will remain open until all sensors have been allocated. Residents and businesses that apply by Jan. 6 will be notified in mid-to-late Jan. 2023 if they have been selected. Subsequent awards will be made monthly until there are no remaining sensors.

The easy-to-install compact air sensors do not have cameras, microphones and do not collect personal information.
