Bad smells, volatile organic compounds, fine dust, pollen, viruses and bacteria can worsen our air quality. Our air purifier Roger shows the air quality at home or in the office. With his two sensors, he continuously measures the quality of the room air and immediately detects contamination. The air quality indicator lets you know if air quality deteriorates by changing its color. The specially-developed Dual Filter combines a HEPA and activated carbon filter. The HEPA filter is very efficient at purifying the air of pollutants and the activated carbon filter skillfully eliminates bad smells. Roger takes care of his role as a household air improver even more independently with his auto mode which adjusts the cleaning performance to what is currently needed. Roger sensitively provides clean and healthy air at home and in the office and lets allergy sufferers take a deep breath.
