Laundry appliance having a micro-particle filtration and collection system

A laundry appliance comprising:

• a tub positioned within an outer cabinet, wherein a processing space is defined within the tub;
• a fluid path that delivers a process fluid through the tub for treating articles within the processing space, the fluid path having a recirculating fluid path that recirculates at least a portion of the process fluid;
• a primary filter positioned within the fluid path, wherein the primary filter separates lint particles from the process fluid;
• a micro-particle filter positioned within the fluid path and downstream of the primary filter, wherein the micro-particle filter separates micro-sized particles from the process fluid;
• and
• a secondary flow mechanism that delivers the micro-sized particles from the micro-particle filter to a removable collection chamber.

A particulate filtration system for a laundry appliance, the particulate filtration system comprising:

• a primary filter positioned within a fluid path, wherein the primary filter separates lint particles from process fluid delivered through the fluid path;
• a micro-particle filter positioned within the fluid path and downstream of the primary filter, wherein the micro-particle filter separates micro-sized particles from the process fluid;
• and
• a secondary flow mechanism that delivers the micro-sized particles from the micro-particle filter to a removable collection chamber, wherein
• the secondary flow mechanism is defined by a secondary flow of the process fluid through a downstream side of the micro-particle filter, and
• the secondary flow of the process fluid is a recycled portion of the process fluid that is directed between a backflow pump chamber and the removable collection chamber.
