From Air Purification to

Air System Integration

Traditional air purification solutions typically rely on disposable HEPA filters, which require excessive maintenance and replacement costs. However, large buildings, commercial facilities, and industrial environments require a different, cost-effective approach: integrating clean, eco-friendly air filtration technology into existing ventilation systems.

Integrate IEF purification technology theory and modules into the air handling system. Easy to disassemble and clean, with strong maintainability.


Airdog IEF was developed to address this need.

Built on Airdog TPA® Technology

IEF is based on Airdog's proprietary TPA® active electronic air purification technology. It actively charges particles, collects them electrostatically, uses high voltage to kill germs, and uses washable and reusable components, delivering high efficiency. Low resistance, low energy consumption, and cost-saving for industrial applications.

Behind Airdog IEF

Airdog IEF is developed and manufactured by Suzhou BeiAng Smart Technology Co., Ltd., the technology and manufacturing organization behind the Airdog brand.

Suzhou BeiAng has developed air purification technologies and products since 2007, with manufacturing and R&D capabilities supporting applications from portable air purification to industrial air filtration.

Focusing on creating high-quality and efficient air comfort solutions for residential and commercial uses. With the mission to improve indoor air quality and promote healthier living, Airdog has developed advanced air filtration technology, TPA ®. It is a washable solution that actively deactivates and collects harmful pollutants/particles from the air, including bacteria/viruses and ultra-fine particles, down to nanometers. Serving 90+ countries and regions with millions of users. It is well recognized by 10K+ hospitals and 6000+ schools worldwide as their clean air primary choice. Whether you're looking to alleviate allergies or asthma or improve the overall air quality in your home or workplace, Airdog provides a reliable, effective, and environmentally friendly solution to help you breathe easier and live healthier.

At present, Airdog has three major production bases in Suzhou, Wenzhou and Hefei, with a factory area exceeding 200,000 square meters.

Air Treatment for Mushroom Cultivation: Managing Fungal Spores and Microbial Contaminants

Air Treatment for Mushroom Cultivation: Managing Fungal Spores and Microbial Contaminants

For IEF-based applications, the technology can be incorporated into customized equipment according to the specific requirements of the cultivation environment. Specialized systems can combine electrostatic precipitation to address different types of airborne contaminants. The supplied mushroom application demonstrates how a portable air-treatment system can be used in controlled indoor cultivation environments. Mushroom cultivation environments can benefit from careful management of the surrounding air.

How Does Airdog IEF Work?

How Does Airdog IEF Work?

IEF uses Airdog's TPA® (Two Pole Active) technology, derived from ionized wind technology and developed for active electronic air filtration. Airdog IEF uses a four-stage process: pre-filtration, particle charging, electrostatic collection and catalytic filtration. The result is a modular industrial air filtration approach that can be incorporated into suitable HVAC, air handling and ventilation systems.
