The Roger big air purifier ensures clean air in meeting rooms, open-plan offices and large rooms up to 104 m2. The mobile air purifier continuously measures the air quality with its two sensors. Air pollutants such as unpleasant odours, volatile organic compounds (VOC), pollen, fine dust, viruses and bacteria are detected immediately. If the air deteriorates, the air quality indicator informs by means of the changing colour. If the intelligent auto mode is also activated, the cleaning performance adjusts automatically. The more polluted the air, the higher the power level Roger big selects. Furthermore, the sleek air purifier is equipped with two washable textile pre-filters - including an integrated Sanitized hygiene function. The heart of the air purifier is a combination of HEPA and activated carbon filters - the two Dual Filters. Highly efficient, the H12 HEPA filter part filters pollutants such as fine dust, allergens, pollen, viruses and bacteria. The activated carbon filter adsorbs gases from the air. Roger big convinces besides timer, night mode and wheels for transport by its WiFi equipment: monitoring of air quality as well as control of all functions via app. For good and healthy indoor air at all times.
