How Airdog Works
Conventional air purifiers rely on HEPA filters to trap particles. But these filters clog over time, quickly lose efficiency, and require constant replacement. Airdog does things differently.At the heart of every Airdog purifier is its patented TPA® — Two-Pole Active Filtration Technology. It creates a high-voltage electrostatic field that charges airborne particles and pathogens, destroys bacteria and viruses on contact, and captures the debris on washable metal collection plates. These plates are then simply rinsed clean — no replacement filters required.TPA® captures particles as small as 0.0146 microns — including smoke, allergens, chemical vapours, and viruses like influenza — well beyond what HEPA filters can catch. The result is a smarter, cleaner, and more sustainable way to purify the air.
