Signs of Poor Indoor Air Quality in Your Home — Toronto & Scarborough Guide
Canadian homes are sealed tightly against winter cold, which traps pollutants inside. Toronto and Scarborough homes regularly measure indoor air quality 2–5x worse than outdoor air.
Warning Signs Your Home Has Poor Air Quality
- Worsening allergies or asthma indoors — If symptoms improve when you leave the house, the issue is inside
- Persistent musty or stale odours — Sign of mould growth or inadequate ventilation
- Visible mould or condensation on windows — Humidity above 60% grows mould. Install an HRV or whole-home dehumidifier.
- Dust buildup despite regular cleaning — Dirty ducts or inadequate filtration recirculate dust
- Headaches, fatigue, or nausea indoors — Can indicate VOCs, CO, or inadequate fresh air
- Dry, itchy skin or static electricity — Humidity too low (below 30%); install a whole-home humidifier
