Abstract: This application discloses a filtering system, an air conditioning system that includes the filtering system, and a cleaning method for a filtering system. An example filtering system includes a total liquid inlet, a total liquid outlet, a first Y-shaped strainer, and a second Y-shaped strainer. The first Y-shaped strainer includes a first liquid flow port, a second liquid flow port, and a first drainage port. The first liquid flow port is connected to the total liquid inlet by using a first pipeline, the second liquid flow port is connected to the total liquid outlet by using a second pipeline, and the first drainage port is connected to a first waste liquid area by using a third pipeline. The second Y-shaped strainer includes a third liquid flow port, a fourth liquid flow port, and a second drainage port, the third liquid flow port is connected to the total liquid inlet by using a fourth pipeline.
