1. An IV filter, comprising:
a filter housing defining an inlet and an outlet;
a filter media disposed within the filter housing;
a filter channel disposed within the filter housing, wherein the filter channel is in fluid communication with the inlet and the filter media, and the filter media permits flow from the filter channel to the outlet and captures particulate from the flow;
a priming channel disposed within the filter housing, wherein the priming channel is in fluid communication with the inlet and the outlet; and
a disk valve coupled to the filter housing, wherein the disk valve defines a flow portion configured to permit flow therethrough and a seal portion configured to prevent flow therethrough and the disk valve is moveable to (i) direct flow from the inlet to the filter channel in a first position and (ii) to align the flow portion of the disk valve with the priming channel to direct flow from the inlet to the priming channel and to align the seal portion of the disk valve with the filter channel to obstruct flow to the filter channel in a second position.
