Filtration device with releasable additive

A filtration device comprising:

• a filter component, the filter component arranged as a plurality of concentric filtering elements having an outer and inner filtering element, each filtering element having a filter media configured to allow working fluid to flow through the filter media while removing contaminants from the working fluid;
• and
• an additive component constructed and arranged on one longitudinal end of the outer filtering element of the filter component wherein the outer filtering element is shortened relative to the inner filtering element of the filter component, the additive component includes a vessel containing at least one additive material that is configured to be introduced to the working fluid being filtered by the filter component, the vessel having at least one opening that opens into a space between the outer and inner filtering elements so that the working fluid must flow through the outer filtering element before the at least one additive material can be released and the working fluid introduced with the at least one additive material flows through the inner filtering element.
