Providing an effortless user experience, this compact, premium, yet highly effective purifier has a simple one-button interface that is intuitive and easy to control. Visualizing the indoor air quality level helps guide the user in choosing a preferred mode to personalize and optimize the purification. Very easy to clean, the dark bottom lid also indicates when to change the filter. The design carries the same architecture as the 3000i-4000i series, with a balance of power and elegance in a more minimalistic appearance.
