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:
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.
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.
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.

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.
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.
| 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 |
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.
