US Patent 7143898 End-of-line water filter

An apparatus for removing debris and scale from a water line includes a first portion that is attached to a faucet or to an appliance conduit that is, in turn, attached to the faucet. A second portion is attached to an existing angle stop valve. A filter screen is disposed in between the first portion and the second portion. The first portion is able to separate apart from the second portion sufficient to allow removal and cleaning or replacement of the filter screen without requiring disconnection of the second portion from the angle stop valve or the first portion from either the faucet or the appliance conduit.
