The Lowdown on IAQ

- The EPA found that indoor air can be 5X more polluted than outside air – and it’s sometimes as much as 100X more polluted.
- 96% of homes tested had IAQ issues. 86% of these included high levels of ducts, pollen and air-borne viruses. 71% of the air in homes tested was filled with potentially harmful chemicals and gases.
- Improvements in IAQ in the workplace/classroom can increase productivity by up to 10%
- An EPA analysis found that if a school spent just $370 each year on preventative IAQ maintenance for 20 years (a total of $8,140) it would save about $1.5 million in repairs.
- 2 out of 3 indoor air quality problems involve the HVAC system. Many of these are directly related to leaky ventilation shafts and other ductwork.
