Ultra-fine particles
Removal of ultra-fine particles down to 0.0146 microns - 20× the performance of HEPA filtration.
Patented TPA® technology
Most purifiers trap particles in a filter. Airdog's patented TPA® technology destroys them - capturing pollutants down to 0.0146 microns, around 20× finer than HEPA, with washable filters that are free for life.

Watch TPA® filtration in action.
Thirty seconds inside the technology - see how Airdog charges, captures and destroys the particles HEPA can only try to trap.
In one sentence
TPA charges airborne particles and collects them on washable plates - destroying what HEPA can only try to trap.
Read just this, or keep scrolling for the full picture: the five-step process, what it removes, and exactly why it beats HEPA on capability, cost and the environment.

The TPA® purification process
Five stages, from intake to clean air.
From intake to output, Airdog guides air through a multi-stage purification journey that removes pollutants and returns cleaner, healthier air to your space.
-
1
Pre-filter screen
Air flows from the bottom and into the pre-filter screen to collect hair, pet dander and larger particles. -
2
Wire frame
Creates an electro-field that charges the dangerous particles that would otherwise travel into our lungs. -
3
Ionic field
Annihilates bacteria and germs - charged particles are destroyed at a molecular level. -
4
Collecting plates
Charged particles stick to the washable collecting plates, removing dangerous toxins from the air. -
5
Catalyst filter
The final step removes unpleasant odours, keeping your air fresh and pure.

HEPA filtration is rated to 0.3 microns. TPA® captures particles around20×
smaller - reaching the ultra-fine pollutants that do the most harm.
Targeting key health issues
One technology. Twelve everyday threats.
From viruses and bacteria to smoke, allergens and chemical odours - TPA® captures and destroys the pollutants that ordinary filters let slip through.
- Viruses
- Fungus
- Germs
- Pollen
- Dust
- Formaldehyde
- Mites
- Dander
- Smoke
- TVOCs
- PM2.5
- Odours
Washable. Reusable. Free for life.
The last filter you'll ever need is the one in the box.
HEPA filters are disposable. They clog, lose performance and need replacing every few months - costing you money and sending non-degradable waste to landfill, year after year.
TPA® collecting plates simply rinse clean. Wash them, let them dry, slide them back in. No replacements to buy, no performance drop-off, and nothing thrown away - for the entire life of your Airdog.
TPA® vs HEPA
Better by capability, cost and conscience.
HEPA was a breakthrough - in the 1940s. Here's how today's patented TPA® technology compares, point for point.
| HEPA | Airdog TPA® | |
|---|---|---|
| Smallest particle captured | ~0.3 microns | 0.0146 microns - 20× finer |
| How it works | Traps particles in a fibre net | Charges & destroys particles at a molecular level |
| Performance over time | Clogs & declines as it fills | No clogging - retains 99%+ performance |
| Filters | Disposable - replaced every few months | Washable & reusable - free for life |
| Ongoing filter cost | $$ every year, forever | $0 - nothing to replace |
| Waste | Non-degradable filters to landfill | Zero-waste - nothing thrown away |
| Noise | Varies; rises as filter clogs | Optimised aerodynamics - from ≤58 dB |
| Ozone safety | Varies by product | CARB certified - ozone-safe |

Compare the range →Air purifier performance
HEPA fades as it fills. Airdog doesn't.
HEPA filters lose efficiency quickly as they become clogged. Airdog maintains strong performance - up to 50 times better than HEPA - even as its collection plates fill.
Purifier performance against cumulative pollution captured — Airdog (blue) holds near 100%; Normal HEPA (black) falls away.
What is CCM?
Performance over time is measured by a metric called Cumulative Clean Mass (CCM) - how much pollution a purifier can handle before its effectiveness starts to decline.
45
cigarettes
A standard HEPA filter reaches its limit after filtering the smoke of about 45 cigarettes.
440
cigarettes
An Airdog TPA® purifier handles the smoke of 440 cigarettes - with only a 0.2% drop in performance.
Better for the planet
Clean air shouldn't cost the earth.
Every disposable HEPA filter is made, shipped, used briefly and thrown away. TPA® was designed to break that cycle.
Zero
filter waste - washable plates are reused for the life of the product.
No
non-degradable HEPA filters sent to landfill, ever.
Lower
lifetime footprint - nothing to manufacture, ship and replace on repeat.
