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.
