Abstract

Filters and methods of filtering debris from fluid are detailed. A vortex of debris-laden fluid may be created within a filter, causing certain debris (including, for example, leaves) to settle therein. Some versions of the filters may include two stages, one having a perforated tube and a second having a generally frustoconically-shaped tube, which may or may not be perforated.
