Tulip is an air purifier that uses a modern, refined HEPA filter and activated-carbon filter to remove dust, bacteria, viruses and unpleasant smells from the air. Tulip comes in two sizes and is suitable for both living and sleeping areas. The clear and simple design draws the user’s attention to the main display. The control elements, situated in a circle around it, make it very easy to use. This user-friendliness is underlined by the fact that the four buttons, arranged in an intuitive way, are the only controls needed to adjust the air purifier. The central display uses four illuminated coloured indicators to show the current air quality.
