Invention refers to air cleaning systems, which are intended for use in livestock buildings and in different food and other kind of industry, in household insulated rooms for removing odours or aroma and odour-bearing substances, for example, ammonia evaporations, displeasing odour or annoying aroma as well as microbes and dust from room air. The object of the invention is to simplify the air cleaning system, prevent production of big amount of wastewater and on the same time to reduce the total costs. Air cleaning system is provided with recirculation type water supply system maintaining clean water supply to air cleaning chamber (1) connected to used water storage tank (4) which is connected to water purifier (11). Air cleaning chamber (1) is connected to ventilation chamber (2), which is made with several untreated air (A) inlets (3) and to used water storage tank (4) being made as a compact interconnected unit. Water supply system is provided with mist-creating sprayers (5) placed in air cleaning chamber (1) and connected to purified water supply means (6, 10, 12). Exhaust fan (7) is located in zone of outgoing clean air (B). In zone between sprayers (5) and fan (7) in chamber (1) the water-retainer (9) is mounted. Water supply system includes water pump (1) and water purifier (11) as well as clean water reservoir (12), which is connected to additional water supply source. Used water tank (4) is connected to water purifier (11) by discharge pipelines (14). The polluted air (A) is sucked into ventilation chamber (2) and afterwards in air cleaning chamber (1), wherein the sprayers (5) are creating mist removing dust, microbes and odour from air. When the mist is reaching water-retainers (9), discharge water, containing pollutions removed from air, is flowing back to used water tank (4) and afterwards to water purifier (11). Purified water from reservoir (12) through pipeline (6) is discharged back to sprayers (5) creating mist.
