Why Indoor Air Quality Matters

Indoor air quality refers to how clean or polluted the air is inside your home. Everyday things like dust, pet hair, cleaning sprays, mould, or gas stoves can pollute the air you breathe, and it all happens quietly, without you noticing.

According to the World Health Organisation, indoor air pollution causes millions of health problems globally every year. In fact, the air inside your home can be up to five times more polluted than the air outside. That’s especially concerning when you consider that we spend most of our time indoors working, relaxing, or sleeping.

Is Your Home Making You Sick? Look for These Signs:

You often sneeze, cough, or feel short of breath indoors.
You get frequent headaches or feel dizzy at home.
Your eyes, nose, or throat feel irritated.
You see mould, especially in bathrooms or damp corners.
You feel tired or unwell but better when you leave the house.

If these sound familiar, it’s time to make a few changes to improve air quality in your homes.

What’s Polluting the Air in Your Home?

In South African homes, common sources of indoor pollution include:

🦠 Mould and Damp

Places like Cape Town or Durban, which are more humid, often have mould problems. Mould releases spores into the air, which can trigger allergies or asthma.

🧹 Dust and Pet Dander

Dry seasons in cities like Johannesburg increase dust levels. Add pets, rugs, and curtains to the mix, and you’ve got a recipe for poor air quality.

🧴 Cleaning Products and Paints

Many household items — like air fresheners, paint, and polish — contain volatile organic compounds (VOCs), which release harmful gases.

🍳 Cooking Fumes

Gas stoves and wood fires release smoke and gases that can harm your lungs, especially in homes with poor ventilation.

10 Simple Ways to Improve Air Quality in Your Homes

Here’s how to make your indoor air cleaner, fresher, and healthier:

1. Let Fresh Air In

Open windows and doors often. Even a few minutes of fresh air every day helps remove stale air and indoor pollutants.

2. Control Dampness

Use a dehumidifier or moisture absorber in damp areas. Fix leaking taps or roofs, and always dry wet spots quickly to prevent mould.

3. Add Air-Purifying Plants

Plants like peace lilies, snake plants, and bamboo palms absorb toxins and release oxygen. They also brighten up your space!

4. Use Safe, Low-VOC Products

When buying paint, glue, or furniture, look for products marked low-VOC. These are less toxic and safer for your family.

You can check recommendations at GBCSA, which promotes eco-friendly buildings in South Africa.

5. Switch to Natural Cleaning Products

Make your own cleaners using vinegar, lemon, and baking soda. They’re affordable, effective, and don’t pollute your air.

6. Vacuum and Dust Often

Clean your floors, furniture, and curtains weekly. Use a vacuum with a HEPA filter to trap tiny particles like pet hair and dust.

7. Say No to Indoor Smoking

Cigarette smoke contains thousands of harmful chemicals. If someone in your household smokes, ask them to smoke outside, away from open windows.

8. Test for Carbon Monoxide

Gas stoves, heaters, and generators can release carbon monoxide, a dangerous gas you can’t see or smell. Install a carbon monoxide detector to stay safe.

9. Use an Air Purifier

A good air purifier with a HEPA filter can remove allergens, smoke, and even germs from the air. These are especially helpful for people with asthma or sinus problems.

10. Clean and Groom Pets Regularly

Brush your pets often and keep them off beds and couches. Pet dander (tiny bits of skin and fur) is a major cause of allergies.

Create a Healthier Home for Your Family

Improving indoor air quality isn’t something you need to do all at once. Small steps like opening windows, cleaning regularly, or switching to safer products — can make a big difference.

Whether you live in a modern apartment in Sandton or a cosy home in Soweto, these practical tips will help you improve air quality in your homes and create a healthier space for everyone.

Clean air doesn’t just help you breathe better; it helps you sleep better, think clearly, and live longer.
