Easy Ways to Improve the Air Quality in Your Home

You might think the air inside your home is cleaner than the air outside, but in reality, indoor air can be more polluted. Your home can harbour many airborne toxins, from aerosols and mould spores to dust mites and pet dander. These pollutants can affect your health and overall well-being.

The good news is that improving indoor air quality doesn’t have to be complicated. You can create a fresher, healthier environment for yourself and your family with a few simple changes. Whether you suffer from allergies, have respiratory issues, or simply want to breathe cleaner air, these practical tips will help.

1. Keep Shoes Off Indoors

A simple yet effective way to reduce indoor pollutants is to leave your shoes at the door. Shoes track in dirt, bacteria, chemicals, and allergens from outside. By switching to indoor slippers or going barefoot, you’ll minimise the contaminants brought into your living space. As a bonus, your floors will stay cleaner for longer.

2. Avoid Smoking Indoors

Cigarette smoke contains thousands of harmful chemicals, including carbon monoxide and formaldehyde. These toxins linger in the air long after smoking has stopped, contributing to long-term indoor pollution. If you or someone in your household smokes, take it outside to protect the health of your family—especially children and pets. If quitting is an option, even better.

3. Reduce Aerosol Usage

Aerosol sprays, such as air fresheners and hairsprays, release volatile organic compounds (VOCs) that pollute indoor air and irritate the respiratory system. Instead, opt for natural alternatives like essential oils or fresh air circulation by opening windows. For personal care, switch to pump bottles or solid products that don’t release harmful chemicals.

4. Control Humidity Levels

Excess moisture creates the perfect breeding ground for mould and dust mites—common allergens that can trigger asthma and respiratory issues. Keep your home’s humidity between 30% and 50% using a hygrometer (an inexpensive tool available in most hardware stores). If humidity levels are too high, use a dehumidifier or ensure proper ventilation in moisture-prone areas like bathrooms and kitchens.

5. Improve Ventilation

Proper ventilation is essential for flushing out indoor pollutants. Open windows regularly, even in colder months, to let in fresh air. If your home is well-sealed for energy efficiency, invest in a mechanical ventilation system or an air purifier to improve air circulation.

6. Use Air Purifiers

Air purifiers help remove airborne contaminants like dust, pollen, pet dander, and smoke, making them particularly beneficial for allergy and asthma sufferers. Choose a model with a HEPA filter for the most effective air filtration. Place air purifiers in frequently used rooms, such as the bedroom and living room, for the best results.

7. Choose Safer Cleaning Products

Many commercial cleaning products contain harsh chemicals that release toxic fumes. Switch to eco-friendly cleaning products or make your own using natural ingredients like vinegar, baking soda, and lemon. These alternatives are safer for both your health and the environment.

8. Keep Pets Groomed

Pet dander and fur can contribute to poor air quality. Regular grooming and cleaning the areas where your pet spends the most time can help reduce airborne allergens. Brushing your pet outside and washing bedding frequently can also make a difference.

9. Clean Carpets and Upholstery Regularly

Carpets and upholstered furniture trap dust, allergens, and bacteria. Vacuum regularly using a HEPA-filtered vacuum to reduce pollutants. Periodically steam-clean carpets and upholstery to remove deeply embedded dirt and allergens.

10. Add Houseplants for Natural Air Purification

Houseplants not only brighten up your home but also help filter the air. Certain plants, such as spider plants, snake plants, and peace lilies, absorb pollutants like formaldehyde, benzene, and carbon monoxide. Adding a few air-purifying plants to your living space is a natural way to enhance indoor air quality.

11. Replace Air Filters Regularly

Your home’s heating and cooling systems use air filters to trap dust and pollutants. Over time, these filters become clogged, reducing their effectiveness. Change or clean filters regularly—especially if you use air conditioning or heating frequently—to keep your air clean and your HVAC system running efficiently.

Breathe in Fresh, Clean Air

Improving indoor air quality is easier than you might think. Small changes, like removing shoes at the door, limiting aerosol use, improving ventilation, and managing humidity, can significantly enhance the air you breathe. By implementing these simple steps, you can create a healthier home environment for yourself and your loved ones.
