One embodiment of the invention provides an air treatment device. The air treatment device comprises: an air purifying unit, configured to purify air; an air sensor, configured to measure a first air quantity and provide a measurement output, wherein the first air quantity comprises the purified air purified by the air purifying unit; and a processor, configured to generate a first value based on the measurement output of the air sensor so as to calibrate the air sensor. With the air treatment device of one embodiment of the invention, clean air, i.e. zero air, is generated locally by the air treatment device so as to calibrate the air sensor, without the need for externally generating the zero air, which brings convenience for the user or other operators performing calibration of the air sensor of the air treatment device. Another embodiment of the invention also provides a method of calibrating an air sensor of an air treatment device. The method comprises the steps of: purifying air by using the air treatment device; and measuring a first air quantity by using the air sensor to get a first value so as to calibrate the air sensor, wherein the first air quantity comprises the purified air.
