A fluid filtering device comprising a housing having an interior chamber with an open top and an inlet and outlet open to the chamber. An annular seat is secured to the housing within the chamber in a position spaced downwardly from the open top so that the seat protrudes inwardly into the chamber and forms an axially extending surface having a seal member. A filter element is removably insertable into the chamber through its open top and to a filtering position in which the filter element is positioned in between the housing inlet and outlet. The filter element includes an outwardly flanged portion which abuts against the top of the seat when the filter element is in its filtering position while the seal member sealingly engages an axially extending surface of the filter element. A cover is detachably secured across the open top of a housing while an elongated handle is secured at one end to the filter element and its other end is positioned adjacent the intersection of the cover with the housing. The handle facilitates both the insertion and removal of the filter element from the housiong chamber and, in addition, secures the filter element against any loss of seal with respect to the housing during operation of the filtering device.
