Abstract: The present application discloses a humidification and purification apparatus, which includes: a machine body provided with an air inlet and an air outlet; a purification and humidification module disposed in the machine body and close to the air inlet; and a blower disposed in the machine body and close to the air outlet. The purification and humidification module includes: a humidification module including a wet pad water tank, a wet pad and an elevation mechanism. The elevation mechanism is connected to the wet pad and is configured to drive the wet pad to move, and the humidification module can be switched between a humidifying state and a non-humidifying state. In the humidifying state, part of the wet pad is immersed into the water in the wet pad water tank, and in the non-humidifying state, the wet pad is lifted above the water level of the wet pad water tank.
