A filter has first and second fittings, a permeable filter medium, and a housing. The housing defines a fluid flow path within the housing between the first and second fittings, and the permeable filter medium is arranged in the fluid flow path to remove one or more substances from a fluid flowing along the fluid flow path. A finger hold is positioned in an upper region of the housing, the finger hold defining a space that is sufficient to allow one or more fingers of an operator to fit in the space and grasp the filter. |
