Claim 20:
21. An air cleaner comprising:
a first inlet located at a lower part of the air cleaner;
a first filter assembly at the lower part of the air cleaner where the first inlet is located;
a sensor to sense at least a degree of indoor air contamination, data resulting from sensing by the sensor being used to provide an indicator corresponding to the degree of indoor air contamination;
a first fan, above the first filter assembly, the first fan being rotated based on the degree of indoor air contamination sensed by the sensor being equal to or higher than a value and being rotated based on the degree of indoor air contamination sensed by the sensor being lower than the value to move air from the first inlet to pass through the first filter assembly and flow along a vertical direction;
a first outlet through which air is discharged along a lateral direction of the air cleaner;
a second filter assembly above the first fan;
a second inlet formed at least at a portion of a side surface of the air cleaner;
a second fan, above the second filter assembly, the second fan being rotated based on the degree of indoor air contamination sensed by the sensor being equal to or higher than the value to move air from the second inlet to pass through the second filter assembly and flow along a direction toward an upper portion of the air cleaner, and the second fan not being rotated based on the degree of indoor air contamination sensed by the sensor being lower than the value; and
a second outlet through which air is discharged along the direction toward the upper portion of the air cleaner and
a discharge member including the second outlet and configured to move relative to the upper portion of the air cleaner such that the second outlet is movable between a first position and a second position,
wherein the air cleaner operates in one of a first discharge mode and a second discharge mode and controls a direction of air discharged from the air cleaner whereby:
in the first discharge mode, the second outlet is at the first position and the second fan is not rotated based on the degree of indoor air contamination sensed by the sensor being lower than the value, and
in the second discharge mode, the second outlet is at the second position, different from the first position and protruding upward from the first position, based on the degree of indoor air contamination sensed by the sensor being higher than the value,
wherein, in the second discharge mode, both the first fan and the second fan are rotated and the air drawn into the air cleaner is discharged through both the first outlet and the second outlet.
