Airdog Air Quality & Technology Insights

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.

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.

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.

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.

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 mos

Many buyers focus only on CADR or filter type, while overlooking other factors that significantly affect long-term performance, maintenance costs, and everyday user experience. This guide explains the 10 most important features to consider before purchasing an air purifier—and why these features matter in real-world use.
