Abstract: The invention relates to a new centrifugal filter for filtering impurities from liquid. Embodiments comprise a cylindrical housing having: (1) a top flow guiding assembly with a top portion having a first liquid outlet, a threaded middle portion, a bottom portion having a plurality of spiral flow guiding grooves adjacent the bottom portion, and a channel through a longitudinal axis; (2) a water inlet flow guiding assembly having a middle portion with a liquid inlet, and a channel through a longitudinal axis; (3) a recessed flow guiding assembly having a channel through a longitudinal axis which forms a conical taper; and (4) an impurity flow guiding assembly having a channel through a longitudinal axis that forms a second liquid outlet; each assembly releasably attachable within the cylindrical housing through threaded means.
