Abstract: A refrigerator includes a rear assembly panel coupled with an assembly cover panel that includes at least one vent. At least one circulation fan is positioned between the rear assembly panel and the assembly cover panel and is proximate the at least one vent. A filter is positioned between the rear assembly panel and the assembly cover panel and is coupled to a photocatalyst to form an activated carbon filter. A light-emitting diode (LED) panel assembly includes a plurality of LEDs positioned on the rear assembly panel and is positioned to project light on the activated carbon filter. An air circulation path extends through the at least one vent and the activated carbon filter and is configured to direct air along the air circulation path, and the activated carbon filter is configured to filter airborne bacteria and particulate matter from the air as the air passes through the activated carbon filter.

Abstract: A refrigerator includes a cabinet coupled to one or more doors forming a storage compartment. The refrigerator additionally includes a first fan assembly positioned on an interior surface of a first cabinet wall, and a second fan assembly positioned on the interior surface of a second cabinet wall. The first and second fan assemblies each include: two or more circulation fans; a filter coupled to a photocatalyst to form an activated filter; and a plurality of UV LEDs positioned to project light on the activated filter. An air circulation path is configured to direct air born bacteria and particulate matter within the storage compartment contemporaneously into the first and second fan assemblies using the two or more circulation fans and circulate filtered air into the storage compartment through the activated filter disposed in the air circulation path.
