Airdog is a global air technology brand focused on air purification and air quality solutions for homes, offices, commercial environments, and larger-scale applications.
With technology origins dating back to 2007, Airdog grew from early research into ionic-wind technology in Silicon Valley into an international brand offering air purification products and related air quality technologies. Today, Airdog products are sold in markets around the world, with products reaching 96 countries and regions as of 2026.
Airdog's core air purification technology is TPA® (Two-pole Active filtration technology), a technology developed and continuously advanced by Suzhou Beiang Smart Technology Co., Ltd.
Airdog is a brand built around air purification technology and innovation.
Its product portfolio includes air purifiers for residential, office and commercial environments, as well as broader air-quality products such as humidifiers, fans and industrial air purification modules.
For larger commercial and industrial applications, Airdog also offers IEF (Ionic Electric Filter) technology modules. These modules can be integrated into larger air-handling and air-treatment systems.
Rather than being limited to a single type of air purifier, Airdog's broader goal is to develop technology and products that improve the quality of the air people experience in different environments.
Airdog's technology origins date back to 2007 in Silicon Valley.
In 2007, Dr. Yan Zhang and Dr. Hongyu Ran, while working in Silicon Valley, established Silicon Valley Air Expert to explore technologies and products related to air.
During early technology development, the team investigated ionic-wind technology. Originally explored as a way to create silent airflow, ionic wind also revealed an unexpected ability to interact with airborne particles.
This discovery led the team further to investigate the use of ionic-wind principles for air purification.
After years of research and development, the technology evolved into a washable and reusable air purification approach designed to reduce dependence on conventional disposable filter media.
The early ionic-wind technology became an important technological foundation for the later development of Airdog's TPA® technology.
In 2009, the founders returned to China and established Beiang Air Tech Ltd., which later became Suzhou Beiang Smart Technology Co., Ltd.
The company began applying ionic-wind air purification technology to practical products and developed capabilities covering research, development, manufacturing and commercialization.
Over the following years, the technology continued to evolve.
In 2014, the technology was formally developed and defined as TPA® — Two-pole Active filtration technology. The Airdog word and graphic trademarks were also filed in China during this period, marking an important stage in the development of the Airdog brand.
The technology and product platform continued to develop as Airdog expanded into international markets.
TPA® stands for Two-pole Active filtration technology and is Airdog's core air purification technology.
The technology combines a high-voltage electric field with electrostatic particle collection.
Instead of relying solely on a disposable mechanical filter, Airdog air purifiers use an electric-field-based purification process to charge airborne particles and collect them on reusable collection plates.
The collection plates can be removed, washed and reused, reducing the need for frequent replacement of conventional filter cartridges.
TPA® is therefore an important part of what differentiates Airdog from many conventional filter-based air purification systems.
Airdog's approach is based on continuously developing electric-field and electrostatic purification technology and applying it to practical air purification products.
One of the areas in which Airdog has conducted laboratory testing is the capture of extremely small particles.
Airdog testing has demonstrated particle capture at particle sizes as small as 14.6 nm (0.0146 μm) under specified laboratory conditions.
This result comes from controlled laboratory testing and should be understood within the conditions and methodology of the relevant test rather than as a universal claim for every real-world environment.
The test data demonstrates Airdog's focus on developing air purification technologies capable of addressing very fine airborne particles.
Airdog is an international air technology brand owned and developed by Suzhou Beiang Smart Technology Co., Ltd.
Suzhou Beiang is responsible for the core technology development, product research and development, manufacturing and continued technological advancement of Airdog products.
The company is also the owner of the Airdog brand and related trademarks in major markets.
Airdog's core products are developed through the company's research, testing, engineering and manufacturing capabilities, while production may be carried out through its manufacturing facilities according to product and capacity requirements.
This means that Airdog is not simply a trading or marketing brand. Its products are supported by an underlying technology, R&D and manufacturing system.
Airdog has developed an international business network covering multiple regions around the world.
As of 2026, Airdog products have been sold in 96 countries and regions.
Depending on the market, Airdog works with regional distributors, agents and local service partners. These partners support local sales, marketing and customer service, while Airdog provides product information, technical support, after-sales assistance and other necessary resources.
This localized business model allows Airdog to combine its centralized technology and product capabilities with local market knowledge and customer support.
Airdog products are designed for a range of environments.
Airdog air purifiers are used in homes and other residential environments where people want to improve indoor air quality.
Airdog products can also be applied in offices, commercial spaces and other professional environments where indoor air quality is an important consideration.
Airdog IEF (Ionic Electric Filter) extends the company's air purification technology into larger air-handling applications.
IEF is designed as an air purification module that can be integrated into larger air-treatment equipment and systems for commercial and industrial applications.
Although air purifiers remain an important part of Airdog's product portfolio, the brand has expanded beyond standalone residential air purifiers.
Airdog's product and technology portfolio includes:
Air Purifiers
Humidifiers
Fans
Industrial Air Purification Modules
Other Air Quality Solutions
These products reflect a broader approach to air technology rather than a single-product strategy.
Airdog uses “Since 2007” to represent the origins of its technology and entrepreneurial journey.
