ABSTRACT:
An apparatus, system, and method are disclosed for a filter for filtering a dosing fluid in an exhaust aftertreatment system. The filter may comprise a dosing tank configured to contain a dosing fluid, a filter media disposed within the dosing tank, and a support structure supporting the filter media to form a pathway for a flow of dosing fluid. Beneficially, the apparatus, system, and method of the present invention reduce the cost of operation and manufacture of the SCR system.
