For air purifier manufacturers and distributors serving the U.S. market, regulatory compliance is an important part of product selection. In California, applicable indoor air cleaning devices are subject to requirements established by the California Air Resources Board (CARB).
Several Airdog air purifier models are listed in CARB certification records, including models from the X3, X5, X8, PRO, and X1D product lines. This article explains what CARB certification means, how it relates to Airdog's TPA® technology, and why it matters for buyers and distributors serving the California market.
CARB stands for the California Air Resources Board, the California state agency responsible for implementing measures to protect air quality and public health.
California requires applicable indoor air cleaning devices sold or supplied in the state to meet specific regulatory requirements. For electronic air cleaning devices, these requirements include electrical safety and ozone-emission limits.
CARB specifies an ozone emission limit of 0.050 parts per million (ppm), or 50 parts per billion (ppb) for applicable air cleaning devices. Certified products are also required to meet applicable labeling and certification requirements.
Importantly, CARB certification should be understood as a regulatory compliance designation, not as an overall rating of air purification performance. CARB does not evaluate how effectively an air purifier removes particles, odors, viruses, formaldehyde, or other pollutants. Those claims should be supported by separate testing and technical evidence.
Airdog models appear in CARB certification records under specific model numbers and Executive Orders. The exact model number is important because certification applies to the listed product models rather than simply to the Airdog brand as a whole.

Airdog uses TPA® technology, an electro-filtration approach that actively charges airborne particles and captures them on a collection system. Unlike conventional disposable filter systems, Airdog's filtration components are designed to be cleaned and reused.
The TPA® system includes multiple stages, including a pre-filter, particle charging system, collection plates, and a catalyst component. Together, these components are designed to process airborne particles while allowing the main collection components to be cleaned and reused.
CARB certification and TPA® technology represent two different aspects of an Airdog air purifier.
TPA® technology describes how the air purifier works.
CARB certification demonstrates compliance with applicable California regulatory requirements.
CARB's classification of Airdog models as electronic air cleaning devices reflects the type of air-cleaning technology used by these products. CARB certification does not, however, serve as a performance rating for TPA® technology. Air-cleaning performance should be supported by separate laboratory testing and technical evidence.
An important distinction when evaluating air purifiers is the difference between regulatory compliance and product performance.
CARB certification addresses applicable regulatory requirements. It does not establish:
CADR or airflow performance
particle removal efficiency
virus or microorganism removal performance
formaldehyde removal performance
odor removal performance
overall air-cleaning effectiveness
These characteristics require separate performance measurements or laboratory testing.
