Indoor air quality guides

How should indoor air quality be managed in schools and classrooms?

School indoor air quality should be assessed across ventilation, occupancy density, particles, airborne microorganisms, VOCs, and odors—not CO₂ alone. Ventilation remains fundamental; air-treatment equipment should be considered as a complement to the space’s management goals.

Why consider multiple indicators?

Pollutants vary with student count, occupancy time, room size, and airflow. CO₂ can indicate ventilation conditions, but it does not represent particle, odor, or airborne microorganism levels by itself.

What to check in schools

  • CO₂, ventilation rate, and occupancy density
  • Particles and airflow
  • Airborne microorganism test and management evidence
  • Sources of VOCs and odors
  • Filter construction and maintenance status

General management practices

Start with outdoor-air supply and ventilation equipment, then manage pre/post-use ventilation and airflow during busy periods. If air-treatment equipment is added, maintain it according to the product’s application, operating conditions, filter replacement, and cleaning requirements.

When selecting equipment

Do not choose solely by room area. Consider occupancy, purpose, ventilation conditions, and the operator’s ability to maintain the equipment. Check whether the tested model and conditions match the intended space.
