According to the January newsletter from the International Indoor Air Quality Commission, indoor air emissions from dry-process photocopy machines include: VOCs, ozone, and particles. These emissions can contribute to adverse health effects such as eye, nose, and respiratory system irritation, and several are listed as hazardous air pollutants. Now researchers have confirmed that typical office copy machines are often a major source of VOCs in the office environment. A test of 4 photocopiers revealed compounds with the highest emission rates overall were ethylbenzene (28,000 µg/hr), mp-xylene (29,000 µg/hr), o-xylene (17,000 µg/hr), 2-ethyl-1hexanol (14,000 µg/hr), and styrene (12,000 µg/hr). Remove VOCs and other harmful chemicals from the air in your home or office with an air purifier that contains activated carbon. Learn more about air purifiers with the Air Purifier Buying Guide.
