The present invention relates to a structural improvement of a filter casing comprising a base and a cover. The base contains an accommodating space to install a filter module, wherein two edges of the accommodating space are respectively integrated with at least two or more fasteners that extend by leaning inwards, making the cover assemble and cover up the opening of the accommodating space of the base, while two edges of the cover are integrated with at least two or more locking holes used to engage and fix the fasteners on the two edges of the accommodating space correspondingly, thus accelerating the assembly of components in a filter, reducing the assembly procedures and time and enhancing the quality and production of filters.
