  • the air cleaner unit according to the invention combines the optimization of the flow conditions with the function of support elements in which functional elements, for example for air purification, in particular filters or electrodes, are optimized for their functions. As a result, the delivery volume, the reduction of noise and odor removal can be optimized. Other functions of the air cleaner unit, which can be realized by additional elements, for example, serve the safety of the user.
  • the present invention has a number of advantages.
  • an air cleaner unit for use in combination with extractor hoods is provided, in which the air flow in a certain way in the air treatment room, and in particular in the reaction chamber, can be performed.
  • other functions can be linked to the air cleaner unit, such as the inclusion of certain components, which are also referred to as functional elements and, for example, electrodes for generating of a DBE plasma.
  • the air cleaner unit according to the invention it is possible by the air cleaner unit according to the invention to provide a defined interface to the hood.
