Abstract: A laundry appliance includes a cabinet, a tub, and a pump for recirculating wash fluid from the tub to a filter container. The filter container includes a fluid inlet in fluid communication with the pump and fluid outlet in fluid communication with the tub. The filter container also includes a filter housing for directing wash fluid from the fluid inlet to the fluid outlet. A self-clearing filter assembly is provided within the filter housing. The self-clearing filter includes side walls and a filter base having at least one inclined surface. The self-clearing filter is situated such that the inclined surface is below the fluid inlet. The self-clearing filter prevents microfibers and other debris from passing through to the outlet of the filter container. Simultaneously, the force of the wash fluid on the inclined surface forces the microfibers and other debris to a trough, where it can be collected and disposed of.
