Abstract: A filter arrangement for a vacuum cleaning appliance includes: a filter enclosure having an enclosure opening; a filter configured to be received through the enclosure opening into the filter enclosure in an insertion direction; and retention means operable between latched and unlatched states for releasably retaining the filter in the filter enclosure. The filter includes an actuation portion configured to operate the retention means, wherein the actuation portion is moveable between at least first and second positions and is biased towards the second position. When the filter is in the filter enclosure, movement of the actuation portion in the insertion direction from the first position to a depressed position transitions the retention means to the unlatched state, whereinafter the actuation portion is moved to the second position in which at least a part of the actuation portion is elevated above the enclosure opening.
