Enhanced fluid filtration methods, systems, and techniques are disclosed that can leverage the function of a supplemental pump in combination with the existing components of a machine, such as the main pump of an electrically-powered machine with an engine. In various embodiments, a supplemental filter apparatus may be operatively associated with the supplemental pump to provide filtration of fluid flowing through the machine. A control module may be operatively associated with the supplemental pump and/or various components of the machine. The control module may be programmed to activate or deactivate the supplemental pump, a valve, or take other actions in association with detecting the existence of one or more filter triggering conditions.
