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.
