  • an additional health aspect can be taken into account, namely the improvement of the quality of the ambient air.
  • air filtering can improve the health aspect that pathogens, for example viruses, can be filtered out of the ambient air and thus the risk of infection and the spread of diseases can be reduced.
  • the furnishing element can take on the additional function of air filtering in addition to the primary function (sound absorption) and, for example, no separate air filter device has to be provided. This is also advantageous from an optical point of view and / or space reasons.
  • the function of air filtering is integrated into the furnishing element.
  • the furnishing element then has an integrated air filter in addition to its primary function (sound absorption).
  • the flat furnishing element has a sound absorption area for absorbing sound
  • this primary function of the furnishing element is combined with the further function of air filtering.
  • noises caused by the air filtering are also absorbed with the aid of the sound absorption area of the furnishing element.
  • Furnishing elements have the advantage that possible noises caused by air filtering are absorbed again.
  • the flat furnishing element can be distinguished by its flat extension within a plane.
  • the furnishing element can be referred to as an acoustic element.
  • the furnishing element is preferably movable, in particular a room divider.
  • the furnishing element can be a partition wall.
  • the furnishing element can be fixed or mobile.

  • a radial fan can be used as the fan, for example an EC radial fan RadiCal from ebm-papst.
  • An axial fan is also conceivable.
  • a particulate filter or so-called HEPA (High Efficiency Particulate Air) filter for example from camfil, can be used as the filter.
  • a filter can consist of several sub-filters; several filters can be provided.

  • the air inlet opening can be at least partially surrounded by the sound absorption area or on the same side of the furnishing element as the
  • the suction device, the air filter and / or the air duct can be located at least in sections within the sound absorption area. This enables a particularly good integration of the air filtering with the sound absorption. In particular, a desired area can then not only be sound-absorbing and thus be sound-reduced, but the air present in this area is also cleaned. This enables the simultaneous improvement of the impairments that can affect a person staying in this area.
  • the air filter is preferably a surface filter and is preferably arranged on the surface of the furnishing element and / or in the air inlet opening.
  • the air filter can be arranged essentially flush with the sound absorption area.
  • the air filter can be provided directly at the air inlet opening so that the air is filtered immediately upon entry into the furnishing element. This has the advantage, for example, that unpurified ambient air is only present outside the furnishing element, but not inside it.

  • the air outlet opening is preferably arranged outside the sound absorption area or facing away from the sound absorption area. It is further preferred that the air outlet opening faces away from the air inlet opening and / or is arranged at a distance from the air inlet opening. It can thereby be achieved that the air is discharged through the air outlet opening at a point on which the furnishing element should not predominantly act.
  • the dedicated environmental area can thus be improved for a person who is in the vicinity of the sound absorption area, where the
  • Air inlet opening is arranged so that this person benefits from the sound absorption and the removal of contaminated ambient air.

  • the air outlet opening and the air inlet opening are located at different points on the furnishing element.
  • the air outlet opening can define the air outlet from the furnishing element, but does not necessarily also imply the return to the environment directly at the air outlet.

  • the air duct is preferably widened at least in sections towards the air outlet opening, preferably funnel-shaped or conical; the volume defined by the air duct can increase in the direction of flow, the volume of the air duct at the air outlet opening being preferably at least 1.2 times, more preferably at least 1.5 times the volume of the air duct at the suction device . Due to the increase in the volume of the air duct towards the air outlet opening, the outlet speed of the air at the air outlet opening decreases. This can reduce airborne noise.
  • the air outlet opening can have at least an area of 0.05 mm ⁇ , preferably at least 0.1 mm ⁇ and / or at least 1/4, preferably at least 1/3, of the outer dimension of the furnishing element in the plane of its extent (height or Width).
  • the air duct can, preferably towards the air outlet opening and / or between the suction device and the air outlet opening, be set up at least in sections to have a sound-absorbing and / or sound-absorbing effect.

  • the air duct can be made of wood, for example.
  • the air duct can enclose the air flow completely or in sections. This can mean in particular that the air duct between the air inlet opening and the air outlet opening does not run through sound-absorbing material. This helps ensure that the sound absorption is not exposed to adverse effects that could be caused by the passage of the ambient air. For example, this can prevent particles that are contained in the air from being increasingly deposited on the sound absorption material or the sound absorption structure and possibly impairing the sound absorption properties.
  • the suction device is preferably arranged at least partially or completely within the device element. This enables a compact implementation of the furnishing element according to the invention. However, it is not ruled out that the suction device is located outside the main body of the furnishing element, in particular outside the two-dimensional extent of the furnishing element.

This enables the components of the filter unit to be optimally integrated into the rest of the furnishing element and, in particular, into one "Hiding" the filter unit in the furnishing element, that is to say an inconspicuous integration that essentially does not entail any external changes in the furnishing element compared to a furnishing element without a filter unit.
  • the air inlet opening and the air outlet opening are arranged such that the flow direction of the air between these two openings runs essentially perpendicular to the plane of the furnishing element, i.e. through the element (viewed in depth). This could be implemented in particular with thicker furnishing elements.

  • the sound absorption properties of the furnishing element can be kept high, as unaffected as possible by the additional provision of the filter unit.
  • the furnishing element has an air inlet opening in each case on two preferably opposite sides, in which an air filter is also arranged in each case. This enables effective air cleaning of a larger area of the room, since the furnishing element can effect air cleaning on two sides of the furnishing element.
