Uncover pristine air with Airdog X3, a stylish, minimalist, small-footprint air purifier. 🍃 Airdog’s patented Two-pole Active Filtration Technology® (TPA) sets a new standard, actively destroying >99.9% of germs and capturing particulate as small as 14.6 nanometers—10-20x smaller than HEPA filters can. Small but mighty, the Airdog X3 covers rooms up to 860 sq. ft. (1 air change per hour). For a better cleaning experience, we recommend using it in rooms ranging from 215 sq. ft. (4 air changes per hour) to 287 sq. ft. (3 air changes per hour). Airdog X3 is an essential add-on for your preferred spots—pet space, bedroom, nursery, and more.
