Why Indoor Air Quality Matters for Ontario Homes
Health Canada research shows indoor air is typically 2–5× more polluted than outdoor air. In Ontario, where homes are tightly sealed for 6+ months of heating season and allergy-triggering pollen runs April–October, indoor air quality directly affects respiratory health, sleep quality, and comfort.
- Allergy season: Tree pollen (April–May), grass (June–July), ragweed (August–October) enter through infiltration and the HVAC system. High-MERV filtration captures most pollen before it circulates.
- Winter dryness: Ontario heating season drops indoor RH to 10–20% — causing respiratory irritation, nosebleeds, and increased viral susceptibility. A whole-home humidifier raises RH to the healthy 35–50% range.
- VOC accumulation: In tightly sealed winter homes, VOCs from furniture, paint, and adhesives accumulate. HRV/ERV ventilation continuously dilutes indoor pollutants with fresh outdoor air.
- Pet dander and dust mites: Both are year-round problems. A MERV 11–13 or HEPA filter dramatically reduces airborne concentrations.
