Every building has an air exchange with the outdoors. Leaks, open windows, and weather can all impact how much air gets in. As outdoor air makes its way in, it carries particles with it. This pollution can have an enormous impact on health.

ROCIS (Reducing Outdoor Contaminants in Indoor Spaces) is dedicated to monitoring and improving indoor air quality in the homes and workplaces where people spend their time.

ROCIS Mission

Our mission is to reduce the impact of exterior environmental pollution in southwestern Pennsylvania to create healthy and energy efficient indoor environments.

Simple IAQ Interventions with Big Results

Because most modern air pollution (at least in southwestern Pennsylvania) is so small that it’s more or less invisible, it can be easy to ignore. That’s part of why we run the Low Cost Monitoring Project. Not only do we loan low cost air monitors to our LCMP...

Clean Air Chronicles

Participants in our Low Cost Monitoring Project witness firsthand how outdoor air quality impacts the air inside. As part of our program, they learn what can be done to improve the air in their homes. These short videos capture a few families’ experiences with low-cost monitoring and targeted interventions. Watch their stories and explore other resources related to indoor pollution exposure.
