[origin: WO9801212A1] To provide a filter frame which enables a filtering medium to be easily renewed on a site and makes it possible to provide a filter at a low cost. The filter frame comprises a pair of frame elements capable of being integrally coupled together through flange bonding, each frame element comprising a passage portion allowing the passage of a fluid to be filtered and a flange portion outwardly disposed at a peripheral end portion of said passage portion, and that each of said flange portions has at least one bending portion, and said two flange portions, when coupled together, are engaged with each other based upon at least one tongue-in-groove connecting portion with said filtering medium being sandwiched between said flange portions.
