Solutions · Viruses & Bacteria
Cleaner, healthier air - down to the microscopic
Airborne viruses and bacteria are far smaller than the particles ordinary HEPA filters are rated for. Airdog’s TPA® field is lab-verified to neutralise them.
Why it matters in Australia
Most airborne pathogens are ultrafine
Viruses can be as small as 0.02–0.3 microns - beyond the rated capture size of standard HEPA. Airdog’s charged TPA® field captures and inactivates these ultrafine particles as air passes through.

Patented TPA® filtration, down to 0.0146 microns
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
Can an air purifier reduce airborne viruses?
Airdog is laboratory-verified to remove and inactivate airborne viruses and bacteria. It’s a complement to good hygiene and ventilation, not a substitute for them or for medical advice.
How is TPA® different from HEPA for viruses?
Many viruses are smaller than HEPA’s rated capture size. TPA® captures particles down to 0.0146 microns and inactivates pathogens on its collecting plates.
Is it safe to run around people?
Yes - Airdog is CARB-certified ozone safe, emitting <0.01 ppm ozone (undetectable), so it’s designed to run continuously in occupied rooms.
Does it help in shared spaces like offices or clinics?
Yes. For larger or shared rooms, higher-CADR models (X5D, X8D) refresh the air more times per hour. See For Business for fleet options.
