A filter canister for use within a storm water sewer system. The filter canister includes a hollow retention body and a lower tapered filter. The retention body defines a top and a bottom, and is positionable within the storm water sewer system so as to direct fluid flow from the top to the bottom.

A filter canister for use within a storm water sewer system. The filter canister includes a hollow retention body and a lower tapered filter. The retention body defines a top and a bottom, and is positionable within the storm water sewer system so as to direct fluid flow from the top to the bottom. The lower tapered filter defines a vertex end and a base. The lower tapered filter is attached to the bottom of the retention body such that the vertex end extends upwardly toward the top. In one preferred embodiment, a pelletized treatment media, such as peat-based, activated carbon-like pellets, is contained within the retention body. During use, the treatment media removes contaminants from water flow entering the filter canister. The lower tapered filter directs the removed contaminants toward an outer periphery such that the accumulated contaminants have minimal effect on a flow rate capacity of the filter canister.
