When we think about air pollution, our minds often drift to crowded city streets, billowing factory smoke, and traffic jams. But what many people don’t realise is that the air inside our own homes, the very place we go to relax and recharge, can be just as polluted as the world outside.
Breathing in poor indoor air can take a quiet toll on our health. It can trigger sneezing fits, itchy eyes, or wheezing, and over time, it may even contribute to more serious conditions. The good news is that by understanding the hidden risks and making small, simple changes, you can turn your home into a space where the air is cleaner, fresher, and safer for everyone.
Here, we’ll uncover the common sources of indoor air pollution, explore its effects on your health, and share practical ways to breathe easier.
Understanding Indoor Air Pollution
Indoor air pollution happens when tiny particles and impurities linger in the air inside our homes and buildings, quietly affecting the air we breathe. Because we spend so much of our lives indoors, especially during the colder months, these invisible pollutants can gradually impact our health, often without us even noticing.
“The air inside our own homes can be just as polluted as the world outside.”
Common indoor air pollutants include:
Particulate matter (PM)
These are microscopic airborne particles released from cooking, smoking, candles, and fireplaces. Outdoor air pollution containing PM can also get inside of our homes and get trapped.
Volatile organic compounds (VOCs)
These chemicals are found in everyday cleaning products, paints, and air fresheners.
Mould and mildew
High humidity can encourage mould growth, releasing spores that may harm your lungs.
Carbon monoxide
This is a dangerous colourless, odourless gas that comes from gas stoves, fireplaces, and heating systems. High levels can be deadly, so proper ventilation and monitoring are essential.
Dust and pet dander
These are common allergens that can irritate the respiratory system, especially in sensitive individuals.
Radon gas
This naturally occurring radioactive gas can seep into homes from the ground and increase the risk of lung cancer.
What Are the Health Risks?
The effects of indoor air pollution can sneak up on us in different ways, depending on the type and intensity of pollutants and each person’s unique sensitivity. For many, the impact is felt through certain signs and symptoms, including:
Irritation of the eyes, nose, and throat
Headaches and dizziness
Fatigue and difficulty concentrating
Allergic reactions, including sneezing, congestion, and itchy skin
Long-term damage to the respiratory and cardiovascular systems, increasing the risk of conditions like asthma, bronchitis, high blood pressure, and heart disease
Prolonged exposure may also raise the risk of developing certain cancers
How to Improve Indoor Air Quality
Fortunately, small, intentional steps can make a big difference. By reducing indoor pollution, you can turn your home into a healthier, more refreshing place to live.
"Small, intentional steps can make a big difference to indoor air quality.”
Improve ventilation
Open windows and doors regularly to let fresh air circulate. Use exhaust fans in kitchens and bathrooms to remove extra moisture as well as fumes.
Use air purifiers
HEPA filters capture dust, pet dander, and mould spores. Place purifiers in highly used areas like bedrooms and living rooms, especially if your home has poor airflow. Maintain heating and cooling systems by changing filters regularly, scheduling annual inspections, and keeping vents clear.
Control humidity levels
Keep indoor humidity between 30-50% to prevent mould and reduce dust mites. Use dehumidifiers in damp areas, fix leaks, and dry wet surfaces quickly. Turn on exhaust fans while cooking or showering to minimise moisture buildup.
Reduce indoor pollutants
Keep your home smoke-free to eliminate secondhand smoke, which contains hundreds of harmful chemicals.
Choose household products carefully
Select cleaning supplies, paints, and furnishings with low or no VOCs. Also, trying using natural alternatives like vinegar or baking soda if you can, and store chemicals in well-ventilated areas or outdoors.
Keep your home clean
Vacuum carpets, rugs, and upholstery regularly, as well as wash bedding, curtains, and soft furnishings often to remove allergens. Dust surfaces with a damp cloth to trap particles.
Test for harmful gases
Since radon and carbon monoxide are invisible and odourless, hire a professional to assess your home and install carbon monoxide detectors near bedrooms and fuel-burning appliances.
Introduce indoor plants
Some houseplants, such as peace lilies, snake plants, and spider plants, can help filter toxins from the air, which complement other good air-quality measures.
Breathe Better, Live Better
The air quality in your home has a big impact on how you feel on a daily basis. By making even small, intentional adjustments, you can turn your living space into a true sanctuary; one that supports easier breathing, deeper sleep, and a greater sense of calm and comfort throughout your day.
