Provided is a wall surface greening air purification installation (1) of a wall panel type configuration. The installation (1) includes a plant growth medium (2) having a first surface and a second surface opposite to the first surface. Plant(s) (20) may be planted in the plant growth medium (2) at the first surface thereof. The installation (1) includes a ventilation layer formation segment (4). The ventilation layer formation segment (4) forms a ventilation layer (3) along the second surface of the plant growth medium (2). The installation (1) includes an air permeable member (5) between the plant growth medium (2) and the ventilation layer (3). The installation (1) may include, within the plant growth medium (2), a water-permeable, within-compartment-soil support (6) that divides the plant growth medium (2) into a plurality of compartments and that is configured to support the load of soil within corresponding one(s) of the compartments. The plant growth medium (2) may be configured as a greening module unit such that different greening module units are assigned to respective, different segments.本發明之壁面綠化大氣淨化裝置(1)，為壁面板狀，其包含：植物生育基盤(2)，於一單面種植植物(20)；及通氣層形成構件(4)，形成有沿著該植物生育基盤(2)的另一單面之通氣層(3)。並使通氣性構件(5)夾設於植物生育基盤(2)與通氣層(3)之間。在植物生育基盤(2)內，使該植物生育基盤(2)分為複數之區塊，並使支持區塊內之土壤的負重用之可通水的區塊內土壤支持構件(6)夾設其間。植物生育基盤(2)，亦可在各個區塊作為個別之綠化單元。
