Core Technology

In 2007, Dr. Ran participated in the research and development of cooling for the first-generation ultra-thin MacBook Air laptop. However, Dr. Ran discovered that while ionized wind technology could solve the laptop's cooling problem, it quickly absorbed a large amount of air pollutants, hindering the computer's normal operation and ultimately leading to the project's failure. Dr. Ran's team pioneered a new approach, incorporating ionized wind technology into air purifiers. After three years of research and development, they finally achieved filter-free, consumable air purification. Ionized wind technology is the predecessor of Airdog's patented TPA® technology.

TPA Technology Integrates High-Voltage Ion Fields

TPA technology integrates high-voltage ion fields, electronic materials, aerodynamics and other technologies. It creates a 20,000-40,000 volt high-energy ion field between the emitter wires and the collecting plates, actively capturing dust particles and inactivating bacteria. Compared with traditional HEPA filters, it purifies more cleanly and has longer-lasting performance. It can be washed and reused without consumables, bringing technological innovation in the field of air purification.

Two Pole Active (TPA) technology was an active filtration technology, which is different from the HEPA filter passive filtration.

It is based on Ionic Wind technology and optimized for air filtration.

It enables electrical filtration with high collecting efficiency but low power consumption.

It enables a washable green solution, for which no filter change is needed.

It offers an environmentally green solution!

Double Electrode

Dual-electrode active attack: Capture 0.0146μm particulate matter in one net

The first electrode field and the second electrode field are combined into positive and negative dual electrodes based on an electronic control system to actively capture dust, hair, PM2.5, bacteria, viruses, formaldehyde and other harmful substances in the air. Compared with the passive interception and adsorption of traditional purifiers, it takes the initiative to attack and catch them all in one fell swoop!

A 10,000-Volt Electric Field

Not only adsorb, but also kill

A high-voltage electric field of tens of thousands of volts is formed between the collection electrode and the generation electrode, directly electrolyzing and inactivating harmful pollutants such as bacteria, viruses, and allergens, avoiding the secondary release of pollutants, leaving no hidden dangers, and restoring deeply clean air.


* The special design of the ion chamber structure ensures that the electric field energy does not leak out but only flows within the machine.

Stable Performance

One choice, long-term companionship

Traditional purifiers use HEPA filters for adsorption, which can become clogged with pollutants over time, leading to performance degradation. The hollowed-out ion field in TPA technology is impervious to contaminants, ensuring stable performance that lasts longer.

Traditional purifiers require regular HEPA filter replacement, and frequent consumable replacements add up to rising costs. The unique design of TPA technology allows the dirt collecting plates to be repeatedly washed without replacement, enabling an environmentally friendly, green purification mode without consumables becoming a burden on fresh air.
