As a result of more requests for concepts for air purifiers in museums and exhibition halls, we developed air purifier systems and made them a separate part of our product range. With development and production we made use of our own in-house expertise which our engineers, developers, designers and programmers bring to the development of interactive exhibits. Luftklar was developed in two versions, each in three design variants and with the option of individual customization. Luftklar was made ready for series production within a short space of time - it took just under six months from design, prototyping and initial production to series production. As a result of this series production, 442 Luftklar devices were manufactured and delivered within nine months.
