Why It's Important

  • Indoor air can be two to five times more polluted than outdoor air. 
  • Adequate air ventilation, filtration and exhaust can help reduce the effects of radon and carbon monoxide. Well-maintained systems capture and remove airborne vapor, mold and particles that can be asthma triggers, allergens and infectious or toxic to humans. 
  • Growing evidence suggests that improving outdoor air ventilation can improve student and teacher performance, increase test scores and reduce airborne transmission of infection.

What You Can Do

  • Follow the industry's ventilation standards to provide adequate outdoor air, control moisture and minimize energy costs.
  • Comply with your state's relevant environmental health policies and emergency management protocols when conducting ventilation and filtration maintenance activities.
  • Read the Ensure Good Ventilation section of EPA's model K-12 school environmental health program for more information.
