Air in rooms is often burdened by fine dust, pollen and unpleasant odors as well as viruses and bacteria. But Viktor filters all this through a specially developed HPP Filter System ™ (International patent application pending), thus permitting you to take a deep breath of fresh air! Small and yet great in his own way - Viktor clearly demonstrates what clean air is all about with top CADR values (Clean Air Delivery Rate). The special filter cleanses the air while active carbon eliminates unpleasant odors. And with five capacity stages (extremely quiet to powerful) and dimmable night-mode LED control lights, Viktor will always be a fine companion!
