Indoor air quality (IAQ) is one of those aspects of home comfort that we often overlook. Since we can’t see the air we breathe, it’s easy to ignore potential issues. However, for residents of Canada, where the climate can vary greatly with the seasons, it’s especially important to monitor the air quality in our homes. This article will guide you on how to test your home’s air quality and what steps to take to improve it.

Why Indoor Air Quality Matters

Have you ever wondered why you or your family members frequently sneeze or have allergy symptoms? Poor indoor air quality could be the culprit behind these and other health issues. Polluted air can lead to respiratory problems, worsen allergies, and even contribute to chronic illnesses. Conversely, good air quality helps us feel better, improves sleep, and enhances overall comfort at home.

Common Indoor Air Pollutants

So, what can contaminate the air in our homes? Let’s look at some of the main sources:

  1. Dust and Dust Mites: Household dust, which accumulates on furniture and floors, can contain dust mites—tiny creatures that can trigger allergies.
  2. Mold: Particularly in damp, poorly ventilated areas like bathrooms and basements. Mold not only looks bad but can also be harmful to health.

  3. Pet Dander: Hair and skin flakes from pets can cause allergic reactions.

  4. Volatile Organic Compounds (VOCs): These are emitted by many household products, such as paints, cleaning supplies, and even furniture.

  5. Radon: This radioactive gas can seep into homes from the soil and is a leading cause of lung cancer.

  6. Carbon Dioxide (CO2): High levels of CO2 can indicate poor ventilation.

  7. Carbon Monoxide (CO): A dangerous gas that can be emitted by malfunctioning heating appliances.

Signs of Poor Indoor Air Quality

How can you tell if your home’s air quality is poor? Here are a few signs to watch for:

  1. Frequent Allergic Reactions: If you or your family members are constantly sneezing, coughing, or have nasal congestion, it could be due to poor indoor air quality. Allergens such as dust mites, pet dander, and pollen can accumulate inside your home, triggering these reactions. If these symptoms improve when you leave home, it’s a strong indicator that the indoor air quality may be the issue.

  2. Unusual Odors: Persistent, unusual smells can be a sign of poor air quality. The smell of mold, for example, can indicate the presence of moisture and mold growth in hidden areas like behind walls or under floors. Chemical smells might suggest high levels of VOCs from cleaning supplies, paints, or new furniture. If you notice these odors regularly, it’s worth investigating further.

  3. Visible Mold: Mold growth is a clear sign of a moisture problem, which can lead to poor air quality. Black or green spots on walls, ceilings, or around windows are common indicators. Mold can produce allergens and irritants, and in some cases, toxic substances. Even if the mold isn’t visible, a musty smell can be a telltale sign of hidden mold.

  4. High Humidity: Consistently foggy windows and damp walls can indicate high humidity levels in your home, which contribute to mold growth and dust mites. High humidity makes the air feel stuffy and can exacerbate respiratory problems. Maintaining balanced humidity levels is crucial for both comfort and air quality.

  5. Difficulty Breathing: If you experience difficulty breathing, particularly at night or after returning home, it may be due to pollutants like dust, VOCs, or CO2. Poor air quality can exacerbate asthma and other respiratory conditions, making it hard to breathe comfortably. If you find yourself breathing easier when you’re outside, it’s a strong indicator that your indoor air needs attention.
