How Does Airdog TPA Work?
Airdog TPA® is an active electrical air-filtration technology. It charges airborne particles, uses an electric field to attract them, and collects them on washable collection plates.
Unlike conventional disposable HEPA filters, the main particle-collection system can be removed, cleaned, and reused according to the product's maintenance instructions.
In simple terms:
TPA = Charge → Attract → Collect → Wash → Reuse

Is 14.6 nm the same as PM2.5?
No. PM2.5 refers to particulate matter with an aerodynamic diameter of 2.5 micrometers or less, while 14.6 nm is a specific nanometer-scale particle size. They describe different particle-size scales and should not be treated as interchangeable.

What Is CADR?
CADR (Clean Air Delivery Rate) measures how quickly an air purifier can remove airborne particles from indoor air.
It indicates the volume of clean air an air purifier delivers every minute or hour. A higher CADR generally means the purifier can clean a room faster.
CADR is one of the most widely recognized performance indicators when comparing air purifiers.
