<p>The invention relates to an arrangement for increasing the concentration of negative ions in the breathing air of a closed space. In order to make possible a more uniform distribution of the negative ion concentration inside the space without exceeding the permissible limits for ozone in the breathing air, the invention proposes that - at least one conductor pair is arranged in the closed space, - the conductor pair has a first non-insulated conductor, which is switched as the anode, and a second non-insulated conductor, which is switched as the cathode, with the first and second conductors being arranged mutually parallel at a distance, - a voltage source with an output voltage of between 5 kV - 10 kV is connected to the first and second conductors and - the distance between the first and the second conductor is between 10 - 30 mm.</p> |
