Air purifier Roger Big provides clean air in conference rooms, open-plan offices and large spaces of up to 104 m2. The mobile indoor air purifier measures the air quality using its two sensors. So pollutants are detected immediately and removed by the Dual Filter. If the air quality deteriorates, the air quality indicator changes colour. If the automatic mode is activated, the level of performance of the purifier is adjusted automatically. Roger Big purifies the air efficiently with his two Dual Filters. He removes particles such as fine dust, allergens, pollen, bacteria and viruses from the air as well as gases, unpleasant odours and volatile organic compounds (VOCs) with the same level of efficiency. Roger Bigs impressive features include a timer, night mode, transportation wheels and WiFi monitoring the air quality and controlling all his functions are carried out via an app. Features: Removes 99.9% of SARS-CoV-2 which causes COVID-19* Washable pre-filter integrated hygiene function Air quality monitored and controlled via app Specifications: Dimensions: H:52.0 x W:42.0 x D:34.0 cm Colour: White Guarantee:2 Years Material: Abs, Pp Model Number: R-018
