# Filter tool and related methods

## Abstract

A filter tool and method of removing a filter includes a socket head and a plurality of teeth. The socket head has a proximal end portion, a distal end portion, and an outer wall at least partially surrounding a longitudinal axis and defining a hollow configured to receive at least a portion of a housing of the filter. The plurality of teeth are configured to grip the housing of the filter and further define the hollow. The plurality of teeth are angularly positioned about the longitudinal axis and extend radially inward from the outer wall toward the longitudinal axis and further extend longitudinally toward the proximal end portion. The hollow thus narrows toward the proximal end portion for rotatably gripping the housing of the filter received therein and removing the filter from a filter mount.
