Are old painted classrooms and offices off-gassing chemicals that affect kids' health?

What's actually in it

Schools and offices accumulate VOCs from old paint, furniture, carpet, cleaning sprays, whiteboard markers, and printer toner. Closed buildings with poor ventilation let the chemicals build up over the day. Kids and office workers spend hours in that air.

The worst classrooms are the ones with new carpet, recently painted walls, or a printer in the corner.

What the research says

A 2026 study in Sci Rep measured indoor VOCs across European educational buildings. Many classrooms had risk scores above health-based thresholds, especially for formaldehyde and aromatic VOCs. Buildings with active ventilation systems did much better than those relying on open windows alone.

The team flagged ventilation upgrades as the most cost-effective fix.

For your kid's school, ask about HVAC age and whether windows can open. At home, run a HEPA + activated carbon air purifier in study rooms. Choose low-VOC paint and let new furniture air out for a week before using. Open windows daily.
