Abstract
A collapsible fluid filter is disclosed. The filter comprises, in part, a filter medium for filtering impurities from a fluid and a lower rim sealably disposed around the filter medium. The filter further includes an upper rim and a fluid impervious collapsible wall connected between the upper and lower rims. The filter medium, the lower rim, the collapsible wall and the upper rim define a fluid containing reservoir. The collapsible wall of the filter can be collapsed between the upper and lower rims so as to minimize the volume occupied by the fluid containing reservoir and by the filter for storage purposes and can be expanded between the upper and lower rims so as to maximize the volume occupied by the fluid containing reservoir and by the filter generally during use.
