Abstract: A filtration device for coupling to a drain hole of a sink and to a drainpipe includes a basin, a cartridge outlet tube, an outlet housing, and a collector. The basin has an inlet and an outlet. The cartridge outlet tube extends from the outlet of the basin and has a tube inlet at an upper end thereof. The outlet housing defines a channel fluidly connecting an outer volume of the basin to the tube inlet. The housing channel has an inlet located below the tube inlet. The collector defines a collector chamber in the basin chamber and has a bottom wall located above the housing channel inlet. The collector defines a collector channel fluidly connecting the outer volume to the collector chamber with a collector outlet located above the collector bottom wall.
