Big Blue Filter Wrench
The Big blue filter wrench is used to loosen the base of a standard size water filter housing when changing filters. Standard filter housings are used with cartridges that measure approx. 20″ x 4.5″ and 10″ x 4.5″. This water filter wrench is recommended with four slotted style of filter housing and may not work with other filter housing types but we have found this handle works with most water filter housings.
