Airdog Air Quality & Technology Insights

The Airdog X3D builds on the foundation of the original X3 with a series of design refinements and minor specification updates. The differences can be seen in several details, including the top structure, control panel, AQI display placement, air intake and outlet design, and rear cover. While these updates give the X3D a refreshed appearance and refine certain aspects of its design, the two models share the same core product concept and TPA® air purification technology. Overall, the X3D is an updated version of the X3 rather than a completely new generation of air purifier. Understanding these differences can help you compare the two models more clearly and select the version that best fits your requirements.

What is Airdog TPA Technology? TPA® is Airdog's active air filtration technology that electrically charges airborne particles, attracts them through an electric field, collects them on reusable plates, and integrates additional filtration stages to provide a multi-stage air purification system. In its simplest form: Charge → Attract → Collect → Clean → Reuse. That is the fundamental idea behind Airdog TPA® technology. TPA® stands for Two-Pole Active filtration technology.

How does the Airdog TPA filter work? the short answer is: Airdog's TPA technology electrically charges airborne particles, uses an electric field to attract them, collects them on washable plates, and provides additional treatment through downstream filtration stages. simply: Charge → Attract → Collect → Clean → Reuse. That is the basic idea behind the Airdog TPA filtration system.

CARB certification demonstrates compliance with applicable California regulatory requirements. This article explains what CARB certification means, how it relates to Airdog's TPA® technology, which Airdog models are associated with CARB certification, and why CARB compliance matters when supplying air purifiers in California.

Why are air purifiers so expensive? In this guide, we'll explain the major factors that influence air purifier pricing and help you understand how to evaluate whether an air purifier is truly worth its cost. Understanding these factors makes it easier to choose an air purifier that delivers lasting value—not just a lower price tag.

Airdog X1D was independently tested for particle removal down to 14.6 nm, reaching 100% measured removal efficiency. Airdog X1D progressively reduced measured particle concentrations at 14.6 nm, 51.4 nm and 101.8 nm, reaching 100% reported particle removal efficiency at all three tested sizes at the end of the 50-minute test period.

What happens to an air purifier after it has processed a large amount of cigarette smoke? Does the purification performance remain stable after the purifier has continuously captured a large amount of pollution? We used an Airdog air purifier and a HEPA air purifier to test. The test focused on performance attenuation after continuous exposure to cigarette smoke pollutants.
