Water filtering device equipped with water level adjustment unit

A water filtering device equipped with a water level adjustment unit, comprising:

• an external air inlet through which dust-containing air flows in;
• a dust separator communicating with the external air inlet and separating dust in the inflow air;
• exhaust outlets communicating with the dust separator and discharging the air from which the dust has been separated;
