Clean Air Tech

constantly clean air

By generating an electromagnetic field, harmful particles become charged, allowing even ultrafine contaminants as small as 0.0146 μm to be drawn to the filter—just like a magnet.

Working mechanism for Clean Air

Air is pulled in from the bottom and flows upward. Large particles like hair, pet fur, and allergens are caught by the pre-filter. Smaller particles then enter a high-voltage ionization field, where they're positively charged and broken down—eliminating pollutants like dust, pollen, bacteria, viruses, and particles as small as 0.0146 microns. This helps prevent airborne diseases and protects lung health.

HOW Filtration works?

Ozone removal filter

Airdog’s purification process produces a small amount of ozone, but its ozone removal filter lowers the ozone level at the air outlet to just 0.01 ppm—well below the international safety limit of 0.05 ppm. Additionally, the activated carbon filter helps eliminate odours.

Dust collection filter

Adsorbs charged contaminants down to 0.0146μm.

Ionized Wireframe

It creates an electromagnetic field and charges pollutants with positive ions.

Pre-filter

Removes large dust particles and hair.

Airdog vs other air purifiers

Air purifier performance

HEPA filters lose efficiency quickly as they become clogged. In contrast, Airdog maintains strong performance—up to 50 times better than HEPA—even as its collection plates fill.

This is measured by a key metric called Cumulative Clean Mass (CCM), which indicates how much pollution an air purifier can handle before its effectiveness starts to decline.

A standard HEPA filter reaches its limit after filtering smoke from about 45 cigarettes. An Airdog TPA purifier, however, can handle the smoke of 440 cigarettes with only a 0.2% drop in performance.
