How Climate Change is Affecting Indoor Air Quality in Australia
When most people think of climate change, they picture melting ice caps, rising seas, or extreme outdoor weather. But there’s another impact that often gets overlooked: the air inside our homes, offices, and buildings.
From bushfire smoke to mould-inducing humidity, climate-driven changes in Australia are creating new threats to indoor air quality (IAQ). At LoFlowAir, we help families and businesses stay ahead of these challenges with targeted, effective IAQ solutions.
Key Ways Climate Change Affects Indoor Air Quality
1. Bushfire Smoke Infiltration
Australia’s bushfire seasons are growing longer and more intense, producing airborne smoke filled with PM2.5 particles that easily penetrate indoor spaces. Even buildings far from fire zones can suffer poor indoor air due to wind-carried pollutants.
2. Increased Humidity and Heat
Warmer climates mean higher indoor humidity levels, which can lead to:
- Mould growth behind walls or ceilings
- Increased dust mite populations
- Worsened asthma and allergy symptoms
3. Longer and Harsher Pollen Seasons
Climate change is altering plant cycles, leading to earlier and longer pollen releases. This results in:
- More frequent allergic reactions
- Reduced air quality even in tightly sealed buildings
4. Frequent Flooding and Water Damage
More intense storms and flooding events increase the risk of indoor water damage, often followed by:
- Black mould growth
- Contaminated air due to fungal spores
How to Protect Your Indoor Air from Climate Impacts
Invest in High-Efficiency Air Purifiers
- HEPA + activated carbon units are essential for filtering out bushfire smoke, allergens, and VOCs.
- Look for models that handle PM2.5 and ultrafine particles.
Control Indoor Humidity
- Use dehumidifiers to maintain indoor humidity levels between 40–60%.
-
Helps prevent mould and keeps indoor air breathable.
Strengthen Moisture Resilience
- After floods or heavy rain, conduct regular inspections for damp spots and mould.
- Install smart humidity sensors in vulnerable zones like basements or attics.
Upgrade Your Building Envelope
- Improve seals around doors and windows
- Install filtered mechanical ventilation systems to bring in fresh air without pollutants
Adapt Your Air for a Changing Climate
The climate outside is changing—and it’s changing the air inside, too. But with the right tools and knowledge, your indoor environment can remain a safe, healthy space no matter the season.
At LoFlowAir, we specialise in smart, adaptive IAQ solutions including:
• Air scrubbers and purifiers
• Dehumidification systems
• Real-time air quality monitoring
