A filter setter apparatus includes a housing to which an upper jaw and a lower jaw removably connect. The upper jaw has the shape of a rectangular bar with a plurality of upper jaw overlaps depending from either side of the upper jaw. The upper jaw has a mass causing a gravitational force acting on the upper jaw to clamp a filter inserted between the upper jaw and the lower jaw. The upper jaw partially encloses the lower jaw between the plurality of upper jaw overlaps. A filter setter system incorporates the above housing with a plurality of the above upper jaws and a plurality of the above lower jaws.
