Roger air purifier measures the air quality and detects pollutants immediately. He purifies the air with his Dual Filter™, removing pollutants such as fine dust, pollen, viruses and bacteria as well as gases, unpleasant odours and volatile organic compounds (VOCs) with the same level of efficiency.  If the air quality deteriorates, the air quality indicator lets you know by changing colour and the purification performance is adjusted automatically in intelligent automatic mode. The mobile Roger air purifier has a textile pre-filter with hygiene function. And Roger’s impressive features include not only a timer and night mode but also WiFi: you can monitor the air quality in real time and control all his functions via an app on your smartphone!
