The invention relates to an air decontamination device. The mobile air decontamination device (1) includes: (i) an inlet port and an outlet port； (ii) a dehumidifying means downstream from the inlet port for dehumidifying the air entering the device (1) via said inlet port； and (iii) a means for evaporating a microbicidal material, which is arranged upstream from the outlet port and downstream from the dehumidifying means, and which is intended for vaporizing the microbicidal material in the air flowing inside the device (1). Furthermore, the dehumidifying means includes a compressor (4) connected to the inlet port for compressing the air entering the device (1), a forced-convection condenser (5) arranged downstream from the compressor (4), and a water-separating filter (6) arranged downstream from the forced-convection condenser (5), the device (1) including a means for adjusting the discharge pressure of the compressor (4).本発明は空気清浄装置に関する。移動型空気清浄装置（１）は、（i）吸込口及び吹出口と、（ii）前記吸込口の下流に配置され、前記吸込口を通じて前記装置（１）に吸入される空気を除湿するための除湿手段と、（iii）前記吹出口の上流かつ前記除湿手段の下流に配置され、前記装置（１）内部を流れる空気中に殺菌剤を気化させるための殺菌剤の蒸発手段とを含む。また、前記除湿手段は、前記吸込口に接続され、前記装置（１）に吸入される空気を圧縮するための圧縮機（４）と、前記圧縮機（４）の下流に配置された強制対流凝縮器（５）と、前記強制対流凝縮器（５）の下流に配置された水分離フィルタ（６）とを含み、前記装置（１）は、前記圧縮機（４）からの吐出圧力の調整手段を含む。【選択図】図３
