A fluid filtration system includes a mechanism for monitoring and indicating the volume of fluid that has passed through a filter 30. The mechanism includes a channel 42 in communication with a reservoir 22, a portion of which is visible exteriorly of the housing 12. The channel allows a minor portion of the fluid entering the housing via inlet 14 to flow into the reservoir, while allowing the remaining portion of fluid to flow through the outlet 16. The minor portion of fluid entering the reservoir may or may not have passed through the filter. In various embodiments, the system may also include an indicator such as a float 44, a plunger 54, or dye.

[ What is claimed is:] [1.]1. A fluid filtration system comprising:a housing having an inlet and an outlet;a filter disposed within the housing so that fluid entering the inlet must flow through the filter before exiting the housing through the outlet; anda mechanism for indicating the volume of liquid that has passed through the system;the mechanism comprising a channel disposed within the housing, the channel being disposed between the inlet and the outlet so that a portion of the fluid flowing into the inlet flows through the channel; anda reservoir disposed within the housing, the reservoir in fluid communication with the channel so that fluid flowing into the channel is collected in the reservoir, at least a portion of the reservoir being visible from exteriorly of the housing, wherein the portion of the fluid that flows through the channel flows into the reservoir and is a minor portion of the fluid that flows through the inlet and the remaining portion of the fluid that flows through the inlet flows through the filter and out the outlet.
