EPA provides resources for school officials and staff, teachers, health care professionals, parents, and students to help improve indoor air quality in schools. Read more about:

Why It's Important

  • Studies show that one-half of our nation's 115,000 schools have problems linked to indoor air quality (IAQ).
  • Students are at greater risk because of the hours spent in school facilities and because children are often susceptible to pollutants.
  • The health and comfort of students and teachers are among the many factors that contribute to learning and productivity in the classroom, which in turn affect performance and achievement.

What You Can Do

  • Ensure proper maintenance of the school's HVAC system to promote ventilation.
  • Install and regularly replace filters (high efficiency, if possible).
  • Install carbon monoxide detectors, especially near combustion sources (e.g., boilers, stoves, hot water heaters).
  • Be sure to consider indoor air quality in the design of a new school building.
  • Read the Ensure Good Ventilation component of EPA's model school environmental health program with actions for schools to improve the quality of indoor air.
