When Calgary’s winter settles in, we naturally spend more time indoors, seeking warmth and comfort. However, with our homes sealed tight against the cold, indoor air quality (IAQ) often takes a hit. Stale air, humidity imbalances, and airborne pollutants can cause discomfort and even health issues. So, how can you ensure the air inside your home stays fresh, clean, and healthy all winter long? Let’s explore practical ways to improve indoor air quality, even during Calgary’s harshest months.
1. Keep Your HVAC System in Top Shape
Your heating system works overtime in winter, and a well-maintained furnace is key to good indoor air quality. Here’s how to make sure it’s helping, not hurting.
Change Your Furnace Filter Regularly
Furnace filters trap dust, pet dander, and other airborne particles. In winter, when your furnace runs almost constantly, the filter can clog quickly. Check and replace it every 1–3 months, or more frequently if you have pets or allergies.
Consider a HEPA or High-MERV Filter
Upgrading to a high-efficiency particulate air (HEPA) filter or a filter with a higher Minimum Efficiency Reporting Value (MERV) can capture finer particles, improving air quality without compromising airflow.
Schedule a Furnace Tune-Up
Professional HVAC maintenance ensures your system runs efficiently, circulating clean, warm air. A clean system is less likely to spread dust or combustion by-products.
2. Control Humidity Levels
Winter air in Calgary is notoriously dry, and indoor heating systems often make it worse. Low humidity can cause dry skin, irritated sinuses, and static electricity — not to mention making the air feel colder. On the other hand, too much humidity can lead to condensation and mold growth.
Use a Humidifier
A whole-home humidifier integrated with your HVAC system is ideal, but portable humidifiers can also do the trick. Aim for an indoor humidity level between 30–50%.
3. Ventilate, Even When It’s Cold
It’s tempting to keep windows and doors tightly shut all winter, but that traps pollutants inside. Without fresh air circulation, dust, cooking odors, and even off-gassing from furniture and cleaning products build up.
Use Your HRV or ERV
A Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) exchanges stale indoor air with fresh outdoor air without losing heat.
Kitchen and Bathroom Fans
Turn on exhaust fans when cooking or showering to remove excess moisture and pollutants. Make sure they vent outside, not into the attic.
4. Reduce Indoor Pollutants
Even small changes can make a big difference in the air you breathe.
Vacuum and Dust Regularly
Use a vacuum with a HEPA filter to capture dust, pet hair, and allergens. Don’t forget to clean under furniture and in air vents!
Limit Combustion Pollutants
If you have a fireplace, make sure it’s properly vented and cleaned regularly. Gas stoves can also contribute to poor air quality, so use a range hood while cooking.
5. Get Your Ducts Cleaned
Over time, dust, pet hair, and debris can accumulate in your ductwork, reducing HVAC efficiency and circulating allergens throughout your home.
Schedule a Professional Duct Cleaning
A thorough duct cleaning every 3–5 years (or more often if you’ve had renovations or have pets) can help improve airflow and indoor air quality.
Monitor Your Indoor Air
Technology makes it easier than ever to keep tabs on your home’s air quality.
Use an Indoor Air Quality Monitor
These devices measure humidity, particulate matter, VOCs, and even carbon dioxide levels, giving you real-time feedback on your home’s air health.
Check for Carbon Monoxide
Since furnaces and fireplaces are in heavy use during Calgary winters, a working carbon monoxide detector is essential for safety.
