Classroom Indoor Air Quality (CO2, VOCs, HVAC Inadequacy, Post-COVID Ventilation) — child safety profile
Moderate riskClassroom air quality is often worse than outdoor air and worse than office standards.
What is this product?
Classroom air quality is often worse than outdoor air and worse than office standards. CO2 levels routinely exceed 1,000-3,000 ppm in occupied classrooms (outdoor baseline: 420 ppm), causing measurable cognitive performance decline. Harvard T.H. Chan study: cognitive function scores dropped 21% at 1,000 ppm CO2 and 50% at 1,400 ppm. VOCs from markers, cleaning products, art supplies, and building materials accumulate in poorly ventilated rooms. ASHRAE 62.1 recommends 15 CFM/person for classrooms but 50%+ of US schools fail to meet this standard. Post-COVID: increased awareness led to ESSER funding for ventilation upgrades, but many schools still lack mechanical ventilation — relying on windows that may be sealed or inoperable.
