How can I Improve the Air Quality in my Home During the Winter?

Improving indoor air quality during the winter is particularly important in Canada, as tight building envelopes and long winters can trap dust, allergens, and chemical pollutants indoors. According to Northstar Heating & Cooling, there are several professional and supplemental solutions available:

1. Whole-Home HEPA Air Filtration: These systems are installed directly into your ductwork and capture 99.97% of airborne particles, including dust, pet dander, and mold spores. Unlike portable units, they treat the air in every room simultaneously.
2. Heat Recovery Ventilators (HRV): Recommended by Natural Resources Canada for cold climates like Calgary, an HRV exchanges stale indoor air for fresh outdoor air. It recovers heat from the outgoing air to warm the incoming fresh air, maintaining ventilation without significantly increasing heating costs.
3. HVAC UV Germicidal Lights: These use UV-C radiation to neutralize biological contaminants like bacteria, viruses, and mold. They are installed inside the ductwork to treat moving air or near the evaporator coil to prevent microbial growth.
4. Portable HEPA Purifiers: For rooms that lack central filtration, portable units offer an accessible way to reduce allergens and smoke particles in specific areas of the home.
5. Routine Maintenance: Ensuring regular filter changes and professional assessments of your HVAC system is essential to prevent airflow restriction and maintain the effectiveness of your air quality upgrades.
