11 Top Tips to Improve Indoor Air Quality in Your Home

Updated December 2025

Creating a healthy home environment involves many interconnected elements, and air quality is one of the most vital. The air you breathe every day influences everything from your energy levels and sleep to your mood and long-term health. Poor indoor air quality can contribute to headaches, fatigue, allergies, and respiratory issues—and it can quietly affect your overall sense of wellbeing.

In this post, we’ll explore simple, effective strategies to improve indoor air quality and reduce common household pollutants. From natural purification methods and low-tox swaps to mindful habits that support cleaner air, you’ll learn how to transform your home into a space that nurtures your body, mind, and daily life. Whether you’re starting small or doing a full home refresh, these tips will help you create a healthier, more breathable sanctuary.

1. Improve Indoor Air Quality with Eco-Friendly Paints

Traditional paints often release volatile organic compounds (VOCs) as they dry, which can seriously degrade indoor air quality. These harmful chemicals contribute to pollution and health problems. To improve air quality, choose low-VOC or VOC-free paints that minimise the release of toxins into your home. Eco-friendly paints offer a sustainable solution while ensuring better air for you and your family.

2. Understanding VOCs 

Volatile Organic Compounds (VOCs) are invisible gases emitted from everyday products like paints, solvents, and cleaning products. These pollutants can significantly impact air quality and lead to respiratory issues and allergies. To improve indoor air quality, identify sources of VOCs in your home and opt for low-VOC or VOC-free alternatives. Proper ventilation and air purifiers with VOC filters can also help reduce exposure.

3. Combat Dust Mites to Improve Indoor Air Quality

Dust mites are a common allergen that thrives in humid and warm environments. Their presence can trigger asthma and allergies, worsening air quality. To improve your air quality, regularly vacuum, wash bedding, and invest in allergen-proof mattress covers. Maintaining indoor humidity between 30-50% will also help deter dust mites and mould, contributing to healthier air in your home.

4. Managing Fireplace & Woodstove Emissions

While a fireplace can add warmth and charm to your home, the emissions from burning wood and other fuels can degrade indoor air quality. To improve indoor air quality, ensure your fireplace or woodstove is well-maintained and use dry, seasoned wood. Proper ventilation and a clean chimney will reduce harmful particulate matter and pollutants from entering your living space.

5. Mitigating Pet Dander to Improve Indoor Air Quality

Pet dander and hair can significantly impact indoor air quality, especially for those with allergies. Regular grooming and cleaning will help manage pet allergens. Use air purifiers with HEPA filters to reduce airborne pet dander and hair. Washing pet bedding regularly and vacuuming with a pet-specific vacuum cleaner will further improve air quality in your home.

6. Optimising Natural Ventilation to Improve Indoor Air Quality

One of the simplest ways to improve air quality is by optimising natural ventilation. Open windows and doors when possible to bring fresh outdoor air into your home. For more control, use air purifiers, air quality monitors, and humidity controllers to target specific air quality concerns and create a healthier living space.

7. Harnessing the Power of Lighting

Lighting can influence more than just your mood—it can also impact your overall well-being. The quality and type of lighting in your home can affect your circadian rhythms and sleep patterns. To improve indoor air quality in your home, use natural light where possible and avoid lighting that contributes to heat buildup or poor ventilation.

8. Preventing Mould to Improve Indoor Air Quality

Mould thrives in damp, humid conditions and can greatly diminish the quality of your indoor air. To prevent mould growth, identify areas prone to moisture and address leaks or water intrusion. Use dehumidifiers, exhaust fans, and proper ventilation to maintain dry conditions and prevent mould, which can release spores that degrade air quality.

9. Green Cleaning Products to Improve Indoor Air Quality

Many conventional cleaning products contain harsh chemicals that can pollute the indoor air. To improve the air you breathe, switch to green cleaning products made from biodegradable and non-toxic ingredients. These products clean effectively while protecting your health and the environment, ensuring that your home stays fresh without compromising air quality.

10. Garage Safety to Improve Indoor Air Quality

Garages can introduce pollutants into your home, including carbon monoxide and VOCs from vehicle emissions and chemicals. Ensure proper ventilation in your garage, especially when using vehicles or storing chemicals. Installing exhaust fans or keeping windows open can help vent harmful gases outside, protecting your indoor air.

11. Minimising Pesticide Exposure

While pesticides help manage pests, their chemicals can degrade indoor air quality and pose health risks. To reduce pesticide exposure, adopt integrated pest management techniques that focus on non-chemical solutions like sealing entry points and using traps. When pesticides are necessary, choose low-toxicity options and ensure proper ventilation to avoid air contamination.
