GREENGUARD Indoor Air Quality Certification
The GREENGUARD Indoor Air Quality Certification Program gives assurance that products designed for use in
office environments and other indoor spaces meet strict chemical emissions limits, which contribute to the
creation of healthier interiors. Achieving GREENGUARD Certification gives credence to manufacturers’
sustainability claims, backing them with empirical scientific data from an unbiased, third-party organization.

Indoor Air is 2 to 5 Times More Polluted Than Outdoor Air
Most of our exposure to environmental pollutants occurs by breathing the air indoors. These pollutants come
from activities, products and materials we use every day. The air in our homes, schools and offices can be 2 to
5 times more polluted, and in some cases 100 times more polluted, than outdoor air.
People Spend 90 Percent of Their Time Indoors
Indoor air quality is a significant concern, because when the hours spent sleeping, working in offices or at
school are added up, people on average spend the vast majority of their time indoors where they are
repeatedly exposed to indoor air pollutants. In fact, the US Environmental Protection Agency (USEPA)
estimates that the average person receives 72 percent of their chemical exposure at home, which means the
very places most people consider safest paradoxically exposes them to the greatest amounts of potentially
hazardous pollutants.
