What are The Differences Between The Airdog X3 and X3D?
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.
