Indoor Air Quality Calgary: What’s Really in the Air You’re Breathing? [2025 Guide]
If you’ve been asking yourself, “Why is it so smoky in Calgary?”, you’re not alone. Calgary’s Air Quality Health Index (AQHI) has spiked to dangerous levels in recent seasons, sometimes hitting 10+, which means the air is at a high-risk level for human health. The city recently experienced 52 hours of smoke this season — the highest in years. Wildfire smoke is a big part of the problem. Scientists have found that wildfire smoke is more toxic than other types of pollution, and the microscopic particles it carries can cause inflammation in the lungs. These fine particles (PM2.5) affect everyone — but seniors, infants, pregnant women, and people with respiratory or heart conditions face the highest risks. This guide explains what’s in Calgary’s indoor air quality right now, how it impacts your health, and practical steps you can take to protect your family when the outdoors gets smoky. What’s in Calgary’s Indoor Air Right Now? Your Calgary home’s air is not just “air.” It’s a mix of gases, dust, allergens, and smoke particles that can build up in sealed indoor spaces. Some of the most common pollutants in Calgary homes include: These pollutants often build up to levels 2–5 times higher indoors compared to outdoors, according to environmental health experts. Seasonal factors make things worse: How Poor Indoor Air Quality Affects Your Health The symptoms of poor indoor air quality show up quickly — itchy eyes, runny nose, headaches, fatigue, or difficulty breathing. Over time, the risks become more serious. Certain groups in Calgary are especially vulnerable: Since Calgarians spend about 90% of their time indoors, knowing what’s in your home’s air is essential to protecting your health. Why Is It So Smoky in Calgary? Wildfire activity across Alberta and British Columbia has made smoky skies more frequent in Calgary. When outdoor air is filled with smoke, it quickly seeps into homes through doors, windows, and ventilation systems. Unlike dust or pollen, wildfire smoke particles are so small that standard air filters can’t always catch them. This is why Calgary residents often notice worsening asthma, allergies, and even heart-related symptoms during wildfire season. How to Protect Yourself Indoors The good news? There are practical steps you can take to improve indoor air quality in Calgary homes — even when wildfire smoke makes the outdoors unbearable. Conclusion: Take Control of Your Indoor Air Calgary’s air has become increasingly smoky and unpredictable, making indoor air quality more important than ever. While we can’t control wildfire smoke outdoors, we can take real steps to protect the air we breathe inside our homes. From HEPA purifiers and upgraded HVAC systems to regular maintenance and indoor air quality testing, small actions make a big difference for your health and comfort. If you’re concerned about indoor air quality in Calgary, consider scheduling a professional assessment. Clean indoor air isn’t just about comfort — it’s about protecting your family’s long-term health in a city where smoky skies are becoming the new normal.
