How Airdog Air Purifiers Work — Core Operating Principle


Airdog air purifiers use a TPA (Twin-Pole Active) Ionic Filtration Technology, which is different from traditional HEPA filtration. Instead of trapping particles in a fiber filter, Airdog actively charges, collects, and destroys airborne pollutants using electricity.

This process happens in four key stages:


1. High-Voltage Ionization (Particle Charging)

Air first passes through a Wire Frame, where high voltage creates a strong electric field.

  • This field releases negative ions that attach to airborne particles.

  • Once attached, the particles become negatively charged.

Even ultra-fine particles — including viruses, bacteria, PM0.1, smoke, and allergens — can be charged in this step.


2. Particle Capture on Collecting Plates

After charging, air flows through a set of positively charged collecting plates.

  • The charged particles are attracted and adsorbed onto these plates, similar to how dust sticks to a magnet.

  • This mechanism allows Airdog to capture particles as small as 0.0146 microns, far smaller than the HEPA standard of 0.3 microns.

Because plates don’t clog like HEPA filter fibers, airflow remains strong and consistent.


3. Pathogen Destruction

The high-voltage electric field not only captures particles but also:

  • Destroys bacteria and viruses,

  • Breaks down organic pollutants,

  • Prevents microbial growth inside the machine.

This avoids secondary contamination — a common issue with dirty HEPA filters.

4. Washable Filter System (No Replacement Needed)

The collecting plates can be removed and washed with water.

  • No disposable filters

  • No recurring maintenance cost

  • No waste pollution

This is a major difference from HEPA purifiers, which require regular filter replacement.


Summary of the Working Principle


Airdog purifiers actively charge particles, pull them onto collecting plates using electric attraction, destroy harmful microorganisms, and allow fully washable filtration — delivering high efficiency without the need for disposable filters.


Airdog TPA technology VS HEPA air purifier


Features Airdog Air Purifier HEPA Air Purifier
Filtration Technology Ionic/electrostatic filtration with washable collecting plates Disposable HEPA filter media
Particle Capture Captures down to 0.0146 μm ultra-fine particles Captures down to 0.3 μm particles
Filter Replacement No replacement needed – plates are washable and reusable Requires regular filter replacement (every 6–12 months)
Maintenance Cost Low – only cleaning required High – recurring filter purchase costs
Airflow & Efficiency Maintains strong, consistent airflow (no clogging) Airflow decreases as filters clog
Eco-Friendliness Sustainable, produces less waste Creates large amounts of disposable filter waste
Additional Functions Airdog X8 removes ozone, and Airdog X series monitors air quality Mainly particle filtration only
Long-Term Value High – durable, reusable, cost-saving Lower – ongoing replacement expenses


Summary of the Airdog TPA compared with HEPA


Airdog air purifiers stand out with washable filters, ultra-fine particle capture, eco-friendly design, and lower long-term cost, while HEPA purifiers depend on disposable filters, leading to higher maintenance and waste.
