The invention relates to a moveable air-purifying plant wall and a using method thereof. The plant wall comprises a plant wall body and an air-purifying water tank, wherein a filter material with an air-purifying function is also mounted. According to the moveable air-purifying plant wall, air can be purified by plants; polluted air is absorbed into the water tank and is purified through absorption of water and the filtering and adsorption effects of the filter material; the purified air returns indoors. The moveable air-purifying plant wall can purify the indoor air through multiple effects of absorption by water, filtering by the filter material, absorption by the plants and the like, can purify the pollutants comprising volatile gas pollutants such as PM 2.5 suspended particles, formaldehyde and benzene series in the air quickly and efficiently, and has the characteristics of low energy consumption, high pollution-removing efficiency, low noise and the like.
