When it comes to making your home feel comfortable, most people immediately think of temperature. But there’s another element that’s just as important — and often invisible: the air you breathe.

Whether it’s seasonal allergies, wildfire smoke, or just the dust that collects day to day, the quality of your indoor air plays a major role in how you feel — from how well you sleep to your long-term health. Learning more about indoor air quality and how to improve it can make a noticeable difference in your daily life.

What Is Air Quality, Really?

Air quality simply refers to how clean or polluted the air is in a given space. Outside, it’s usually measured using the Air Quality Index (AQI), which tracks pollutants like ozone, fine particles (PM2.5), and carbon monoxide.

Indoors, things work a little differently — but air quality is just as important, if not more so, especially considering how much time we spend inside.

Some of the most common factors that affect indoor air quality include:

• Dust, pollen, and allergens
• Mold spores and excess moisture
• Chemicals from cleaning products, furniture, and building materials
• Smoke from cooking, fireplaces, or outdoor sources
• Pet dander, VOCs (volatile organic compounds), and poor ventilation

Why Indoor Air Quality Should Be on Your Radar

The average Canadian spends about 90% of their time indoors — even more during those long winter months. And believe it or not, indoor air can be up to five times more polluted than outdoor air.

Here’s why that matters:

• Short-term effects can show up as headaches, fatigue, trouble sleeping, itchy eyes, or worsened allergy and asthma symptoms. Kids, older adults, and those with existing health conditions are especially sensitive.
• Long-term exposure to poor air quality can contribute to more serious health concerns, including respiratory and heart issues.

On the flip side, clean indoor air means easier breathing, better sleep, fewer irritants, and an overall healthier home for you and your family.

How to Tell If Your Home’s Air Needs Help

You don’t need fancy equipment to spot the signs of poor air quality. Just pay attention to what your body — and your home — are telling you.

Some common red flags include:

• Stale or stuffy air that never feels fresh
• Frequent sneezing, coughing, or itchy eyes indoors
• Musty smells or visible mold
• Condensation on windows that doesn’t go away
• Dust that seems to come back right after cleaning

If you notice that you feel better when you’re outside or away from home — and worse when you return — it’s likely your indoor air could use some attention.

Simple Ways to Improve Indoor Air Quality

The good news? You don’t need to do a full renovation to make meaningful improvements. Here are some easy and effective ways to start breathing better at home:

• Let in fresh air. Open windows when the weather allows, and make sure your home’s ventilation system is working as it should.
• Use an air purifier. Especially helpful for allergy sufferers or during wildfire season, a quality purifier can remove particles and contaminants from your indoor air.
• Manage humidity. Use a humidifier in the dry winter months and a dehumidifier when it’s muggy to help prevent mold and respiratory discomfort.
• Keep your HVAC system clean. Replace filters every 1–3 months depending on use and the type of filter. It’s a small step that makes a big impact.
• Choose safer products. Go for low-VOC cleaning supplies, paints, and furniture, and keep rooms well-ventilated when you’re painting or using anything with strong fumes.

Final Thoughts

You can’t always see what’s in the air, but you can definitely feel its effects. Taking steps to improve your home’s air quality can help you feel more energized, breathe easier, and protect your family’s health all year round.

From better sleep to better focus, the quality of your indoor air touches every part of your daily life. And the best part? With a few practical changes, you can take control of your air and your comfort.
