Solutions · Bushfire Smoke
Keep the smoke outside where it belongs
During the 2019–20 Black Summer, over 10 million Australians were exposed to hazardous bushfire smoke for months. A sealed room and true fine-particle filtration is the recommended way to protect indoor air.
Why it matters in Australia
Bushfire smoke is a growing Australian reality
Bushfire smoke is dominated by PM2.5 - fine particles under 2.5 microns that penetrate deep into the lungs and bloodstream. Homes offer only partial protection, as smoke infiltrates through gaps and builds up indoors.
Sydney’s 24-hour PM2.5 peaked near 500µg/m³ in 2019–20 - the national standard is 25µg/m³.
MJA / peer-reviewed researchCanberra’s air quality index hit 5185 on 1 Jan 2020 - around 25× the ‘hazardous’ threshold.

Health authorities recommend a sealed ‘clean-air room’ with continuous fine-particle filtration. That’s exactly what Airdog delivers.
How Airdog helps
Patented TPA® filtration, down to 0.0146 microns
Where ordinary HEPA filters trap larger particles, Airdog’s Toxin Particle Annihilation (TPA®) technology charges and captures pollutants as small as 0.0146 microns - around 20× finer than standard HEPA. Its five-step process targets the microscopic triggers that everyday cleaning leaves behind.
- Captures ultrafine particles, allergens and smoke - not just dust
- Washable, reusable filter plates - no filters to buy and bin
- CARB-certified ozone safe (<0.01 ppm, undetectable)
- Real-time AQI display and app so you can see it working

FAQ
Common questions
How do I protect my home during a smoke event?
Keep windows and doors closed, set up one ‘clean-air room’ (often a bedroom), and run an air purifier continuously. Airdog’s real-time AQI display lets you watch levels drop.
Does TPA® capture bushfire smoke?
Yes. Bushfire smoke is mostly PM2.5; Airdog is lab-verified to reduce PM2.5 by over 99.9% and captures particles down to 0.0146 microns.
Which model should I choose for smoke?
For living areas and open plan, the X5D (up to 35 m²) or X8D (up to 100 m²) move more air faster. For a single sealed bedroom, the X3D is ideal.
Do the filters need replacing after a smoke season?
No single-use filters - Airdog’s plates are washable and reusable, so you simply clean them rather than buying replacements after heavy use.
