Indoor Air Quality is a term used to describe the levels of pollution found in the air in our buildings. Most people spend up to 90% of their time indoors and U.S. Environmental Protection Agency (EPA) studies have determined that levels of indoor pollution may be two to five times greater than outdoor levels. In some extreme cases, levels of indoor pollutants were 100 times higher than outside levels.
What products or factors affect indoor air quality?
Many products affect indoor air quality. Some of the most common include:
- Cleaning products and processes used in the building
- Personal care products used by occupants
- Heating, ventilating, and air conditioning (HVAC) systems
- Building furnishings and floor coverings — furniture, fabric finishes, adhesives, and carpet may emit formaldehyde and other volatile organic compounds (VOCs)
- Copiers and other office equipment —can emit ozone, VOCs, and other toxic chemicals
- Construction materials — paints, insulation, pressed wood, and plywood products can emit formaldehyde and other VOCs
- Pesticides used in or around the building
