A humidity indicating apparatus B for a dehumidifier comprising a housing with a cavity 4 and at least one venting aperture 1211. A top member 111 of the housing has a transparent observation window 1111. A transparent separation plate 2 is disposed in the cavity for dividing the cavity into a storage space (41, Fig 5) communicating with the at least one venting aperture and a thermal insulation space (42, Fig 5) located next to the transparent observation window. At least one color-changing humidity sensor 3 is disposed in the storage space. Condensation is formed when the humidity sensor is regenerated through heating. The thermally insulated space reduces condensation to prolong and improve the life of the humidity sensor. Preferably the apparatus has a locking member 13 disposed between a front casing 11 and a back casing 12 for fastening the front and back casing to each other. Preferably the locking member comprises at least two protruding ribs 131 and at least two ear pieces 132, wherein the each ear piece has a slot 133 to engage with each protruding rib.
