Indoor air quality is something we often overlook, yet it plays a huge role in our daily health and comfort.

Two fundamental concepts to grasp when talking about indoor air quality are air balance and air hygiene. Let’s dive into what these mean in a more intuitive way, with tips to assist you to make your indoor spaces healthier and more comfortable.

Finding the Balance in Your Indoor Air

Indoor air, much like a finely tuned orchestra, works best when all elements are in harmony. At its core, air balance is about managing temperature, airflow, ventilation, and humidity to create an environment that feels “just right” for humans, pets, and even the building itself.

Temperature is a key player in this balance. Most of us feel comfortable when the indoor air sits between 22°C and 24°C, a range that’s often considered the “Goldilocks zone.” Not too hot, not too cold, just right.

Of course, our perception of temperature depends on what’s happening outside. Think about walking into a building set at 22°C on a scorching 35°C summer day, well it feels chilly, doesn’t it? Yet the same temperature feels cozy in the middle of winter. Layers like a cardigan or hoodie can assist you adjust as your body acclimates.

Airflow is another vital factor. It acts like a buffer, moving air around to prevent that “stuffy” feeling while also discouraging moisture buildup and reducing energy waste. Whether it’s a natural breeze through an open window or a fan circulating the air, airflow keeps things fresh and ensures you’re breathing clean, healthy air. Without it, you may notice spaces feeling stagnant, drafty, or even oppressive.

Ventilation ties directly into airflow but focuses on the exchange of indoor and outdoor air. Natural ventilation, it’s like opening windows and doors, it is a simple and cost-effective way to let fresh air in and push stale air out. In cases where natural ventilation isn’t enough, mechanical systems can step in to maintain air quality, though these use more energy.

Humidity also deserves a moment in the spotlight.

The ideal range for relative humidity indoors is between 40% and 60%. Too low, and the air dries out, leaving you with itchy skin and dry eyes. Too high, and you’re inviting dampness, mould, and discomfort. In humid climates or the more humid seasons, like February on the east coast of Australia, a dehumidifier can assist in keeping things in check.

Think of humidity as the glue that holds your air’s balance together—it impacts how your home feels and functions.

Clean Air, Healthy Spaces

While balance is critical, cleanliness, or what we call air hygiene, it is just as important. One of the simplest ways to improve your indoor air hygiene is to regularly open windows and doors. This reduces the buildup of pollutants like carbon dioxide, dust, and volatile organic compounds (VOCs).

Sometimes, maintaining air hygiene means removing or replacing certain sources of indoor pollution. For instance, musty smelling materials or heavily scented cleaning products might need to go. Substituting these with clean, non-toxic alternatives can make a world of difference. Using natural, fragrance-free cleaning products not only improves the air but also feels better for you and your family.

Fresh air can also be engineered into your space.

HVAC systems and air purifiers can assist in managing airflow, though they aren’t a substitute for keeping humidity in check. These tools work well as part of a broader strategy, particularly if opening windows isn’t always practical.

Beyond that, developing good habits can significantly impact indoor air hygiene. Regular cleaning, dusting, and even washing your curtains can prevent pollutants like mould spores, pet dander, and dust from building up in the air you breathe.

The Bigger Picture

When you keep your indoor air balanced and clean, you’ll notice the benefits almost immediately. You’ll feel more comfortable, avoid that mid-afternoon slump, and even sleep better. Plus, you’re creating a healthier space for everyone who enters your home, from your family to your guests.

So, take a moment today to think about your indoor air. Is it too hot or too cold? Too dry or too humid? Does it feel fresh, or is there a lingering sense of stuffiness? Small changes can make a big difference, whether it’s opening a window, investing in a dehumidifier, or switching to non-toxic cleaning products.

Your home’s air has a story to tell, and once you are aware of it, you can make changes that will leave you breathing easier every day.
