Fluid filter removal device and method of use

A device for preventing spillage of a fluid from a fluid filter during removal of the fluid filter, the fluid filter having an outer casing with a casing outer surface and a fluid filter grip end opposite a fluid filter installation end, the device comprising:

• a fluid catch having a filter entry end, a filter exit end, a catch outer surface, and a catch inner surface, said fluid catch configured to circumscribe the casing outer surface of the fluid filter such that the filter grip end can pass through the catch inner surface from the filter entry end to the filter exit end along a circumscription axis;
• and
• a filter spacer configured to maintain a minimum separation between the casing outer surface and the catch inner surface when at least a portion of the fluid filter is circumscribed by the fluid catch;
• and
• a fluid filter sheath having a fluid catch interface, a terminal end opposite the fluid catch interface, a sheath outer surface, and a sheath inner surface, the fluid filter sheath fixed and hydraulically sealed to the fluid catch at the fluid catch interface and proximate the filter exit end of the fluid catch, the fluid filter sheath made of a material impervious to the fluid, the fluid filter sheath configured to receive a portion of the fluid filter, extending beyond the filter exit end of the fluid catch, further configured to prevent discharge of any of the fluid exiting the filter exit end of the fluid catch, and further configured to permit manual gripping of the fluid filter via the fluid filter sheath;
• and
• wherein the fluid catch is manually deformable,
• wherein the fluid catch has a first wall thickness between the catch outer surface and the catch inner surface proximate the filter entry end and a second wall thickness between the catch outer surface and the catch inner surface proximate the filter exit end, and the first wall thickness is greater than the second wall thickness,
• wherein the fluid is at least one of a petroleum or a solvent-based product,
• wherein the fluid filter sheath is manually deformable,
• wherein the sheath inner surface of the fluid filter sheath has a greater coefficient of friction than the sheath outer surface of the fluid filter sheath,
• wherein the terminal end of the fluid filter sheath is configured to extend at least 3 inches beyond the filter exit end when the fluid filter is installed through the fluid catch during an in-use condition,
• wherein the device is made of oleophobic or lipophobic materials,
• wherein the minimum separation between the casing outer surface and the catch inner surface is at least 2 millimeters,
• wherein the fluid filter sheath includes a tactile interface having sufficient ductility to manually locate the grip end of the fluid filter,
• wherein the device is thermally insulating, and
• wherein a portion of the fluid catch is conical in shape.

A method for preventing spillage of a fluid from a fluid filter during removal of the fluid filter, the fluid filter having an outer casing with a casing outer surface and a fluid filter grip end opposite a fluid filter installation end, the method comprising the steps of:

• providing a device for minimizing fluid filter spillage, the device including a fluid catch configured to circumscribe a casing outer surface of the fluid filter, further including a filter spacer configured to maintain a minimum separation between the casing outer surface and a catch inner surface when at least a portion of the fluid filter is circumscribed by the fluid catch, and yet further including a fluid filter sheath fixed and hydraulically sealed to the fluid catch, the fluid filter sheath configured to allow for manual contact with the fluid filter through the fluid filter sheath and further to contain at least a portion of the fluid filter and fluid;
• breaking the fluid filter loose from a secured coupling in an installed condition, such that the fluid is left closed in the fluid filter and the fluid filter is left in a manually removable condition;
• inserting the fluid filter grip end of the fluid filter through the fluid catch and into the fluid filter sheath such that at least a portion of the fluid filter is circumscribed by the fluid catch;
• manually removing the fluid filter from the installed condition via the fluid filter sheath while catching any released fluid in the device;
• transporting the fluid filter and the released fluid while contained in the device;
• and
• disposing of the fluid filter and the released fluid by emptying the device.
