The Core 360 air purifier was developed for one- and two-person households where space is relatively limited. The aim was to make the unit as compact as possible while implementing optimum performance for this size. To this end, all sides are generously perforated to maximise air intake. The control unit has four buttons to which the core functions are assigned, so that the air purifier can be operated intuitively by all age groups. The level of air contamination is indicated by a number on the top display and by coloured lights in four levels on the front. This makes it easy for the user to discern the air quality.
