The indoor air is often contaminated with fine dust, pollen, unpleasant odors, viruses, and bacteria. Viktor filters this polluted air with full commitment, allowing you to breathe freely again. The specially developed HPP filter system cleans the air highly efficiently, and the powerful activated carbon filter eliminates unpleasant odors. With five performance levels (from very quiet to powerful) and the dimmed night mode of its control LEDs, Viktor never disturbs your well-deserved rest.
