Additive dispersing filter and method

A filter, comprising:

• a filter housing defining an inlet fluid opening and an outlet fluid opening, the inlet fluid opening and the outlet fluid opening defining a fluid path through the filter;
• a filter element disposed inside the filter housing, the filter element being disposed in the flow path such that fluid flows through the filter element;
• and
• an additive cartridge for dispersing an additive within the filter housing, the additive cartridge comprising:
• a housing defining a receiving area for receipt of the additive;
• a fluid inlet path through a wall of the housing, the fluid inlet path providing a means for increasing a pressure within the receiving area, the fluid inlet path having an inlet opening disposed adjacent to an outer wall portion of the housing;
• and
• a fluid outlet path through the wall of the housing, the fluid outlet path providing a means for dispersing the additive from the receiving area when the pressure within the receiving area exceeds a predetermined value, the fluid outlet path having an outlet opening disposed adjacent to the outer wall portion of the housing, the outlet opening being covered by a shroud configured to deflect fluid flowing in a first direction away from the outlet opening and the inlet opening of the fluid inlet path is positioned to receive fluid flowing in the first direction;
• and
• wherein fluid flow of the additive through the fluid outlet path is controlled by varying an inlet opening of the fluid outlet path by forming a portion of the fluid outlet path in a surface of a first piece of a two piece connector fluidly coupling the an interior and an exterior of the additive cartridge.
