An attachable and movable deodorizer for enclosed space has a body with a plurality of inlet holes and outlet holes. The body has a fan, a photocatalyst filter, and an ultraviolet (UV) control circuit board connected to an UV-A LED lamp. Whereby the body is able to be disposed or attached in an enclosed space such as trash bins and shoe cabinets and to suck in air in the enclosed space by the fan for the air to pass through the photocatalyst filter and then to be discharged from the outlet holes. With the photocatalyst filter illuminated by the UV-A LED lamp, the stench and dusts in the air is therefore filtered and deodorized in the photocatalysis process.
