A "pad" of the type based on corrugated paper, which is known for the moisturising and cooling of intake air for livestock buildings, is found to be particularly applicable as an effective air cleaner when it is arranged in connection with a collection tank for water with a content of bacteria for decomposition of dust and ammonia, in that the tank water is circulated by a pump down through the pad during circulation of the room air transversely through the pad. With the invention, obnoxious odours e.g. from pigsties can be eliminated in a simple and inexpensive manner. |
