FILTER WRENCH Abstract of the Disclosure A filter wrench includes a cylindrical housing with internal lugs and a centrally positioned punch for draining and removing a screw-on filter having an outer canister and an inner filter element. As the housing is impactively positioned over the filter, the punch successively punctures the outer canister and then the inner filter element before the lugs indent the outer canister and the bottom of the housing abuts the canister. With the punch extending through the punctures, the housing is held on the filter while the outer canister and the inner filter element are drained through passages in the punch and an outlet in the housing. When draining is complete, a formed nut on the outside of the housing allows the filter wrench to be rotated causing the lugs to rotate the filter for removal.
