Indoor air quality (IAQ) isn’t just a buzz‑word—it’s a major factor in your health, comfort and the value of your home. Whether you’re building a new house, renovating or simply upgrading your living space, understanding how to maintain great indoor air quality is essential. In this guide we’ll explore why IAQ matters, common pollutants, and practical steps for better air that keeps you breathing easy.

Why Indoor Air Quality Matters

We spend around 90% of our time indoors, making the air inside our homes a critical health factor. Poor indoor air quality has been linked with respiratory disease, heart disease, reduced cognitive performance and greater health risks for children and the elderly. From a building‑design perspective, good IAQ supports wellness, enhances comfort and adds value to your property.

Common Indoor Air Pollutants to Watch For

Here are some high‑impact pollutants that often go overlooked:

• • Volatile organic compounds (VOCs) from paints, adhesives, furnishings and cleaning products.
  • Particulate matter (PM2.5 / PM10) and combustion by‑products (gas stoves, fireplaces).
  • Biological contaminants: mould, mildew, pet dander, dust mites.
  • Poor ventilation or building design that traps pollutants indoors rather than flushing them out.

How Indoor Air Quality Impacts Your Home & Health

• • • Comfort: Stuffy, damp or odorous air undermines enjoyment of your space.
    • Health: Symptoms like headaches, fatigue, irritation of eyes/nose/throat can be linked to poor IAQ.
    • Productivity & wellness: Cleaner air supports better sleep, concentration and general wellbeing.
    • Property value & durability: A well‑designed home that controls indoor air is more efficient, healthier and more desirable in the market.

Practical Steps to Improve Indoor Air Quality

Here are actionable tips you can implement right now:

• • • 1. Ventilation first – ensure your building design includes cross ventilation, mechanical exhaust, and appropriate air exchange to dilute indoor pollutants.
      2. Choose low‑VOC materials – paints, adhesives, insulation, furnishings: select products with low chemical emissions.
      3. Control humidity – aim for 30‑50% relative humidity to reduce mould growth and dust mites.
      4. Proper combustion & filtration – if you use gas appliances or fireplaces, ensure they are vented correctly. Use HEPA filters or air purifiers if needed.
      5. Smart cleaning habits – minimise use of harsh chemicals, maintain HVAC filters, ensure dust and allergens are removed regularly.
      6. Monitor & design for air quality – include IAQ considerations early in your build or renovation. Use sensors or monitors to track CO₂, VOCs, PM levels.
      7. Commissioning & maintenance – ensure ventilation systems and finishes perform as intended; good IAQ doesn’t end at hand‑over.

Key Takeaway

Indoor air quality is not optional—it’s foundational to health, comfort, and value in your home. By prioritising ventilation, materials, filtration and monitoring, you protect occupants and future‑proof your space.
