Geschäftsführer Herr Robert Krüger


and Mission

We are innovators for better urban air quality

We want to reduce harmful urban pollutants NOW.

  • Our mission is to actively improve the air quality in densely populated urban environments.
  • Our City Air Cleaners provide clean air whereever it is needed.

We believe in technology as a problem solver

We use proven technologies for creating innovative solutions.

  • If it is not possible to avoid the emission of harmful air pollutants in cities in the short term, they must be actively reduced.
  • We use technology to bridge the gap between the desired short-term air quality improvements and more sustainable comprehensive mid to long-term solutions.

We strive for impact for a better quality of life

We want to excel in improving urban air quality.

  • Air quality in cities varies greatly in time and space and must therefore be considered at a hyperlocal level.
  • The increasing use of real-time pollution sensors enables demand-oriented air quality management in zones and periods with harmful concentrations.

Our air purifiers provide clean air effectively wherever and whenever it is needed.
