Cleaning Up Indoor Air

According to researchers, people in developed countries spend 90 percent of their time indoors, potentially breathing air polluted by emissions from indoor sources, such as formaldehyde. One approach to improve indoor air quality is to increase the amount of fresh air intake, the old “dilution is the solution to pollution”.  But increasing fresh air intake brings with it increased energy consumption of energy for heating, cooling and humidifying/dehumidifying.

Members of the Indoor Environment Department of the Lawrence BerkeleyNational Laboratory’s Environmental Energy Technologies Division (EETD) have developed methods for reducing levels of indoor formaldehyde concentrations with a synthetic catalyst and evaluating reduction of other volatile organic compounds with activated carbon fiber filters.
