Abstract
Embodiments of the disclosure provide a faucet with an integral filter for filtering fluid to be discharged from the faucet. A filter casing can house the filter cartridge and can be provided with an automatic shut-off valve actuable by the filter cartridge. The filter cartridge can include an integral check valve at its upstream end to prevent unwanted spillage of fluid from the filter cartridge when removed from the assembled position. A filter mount can selectively keep the faucet and the filter cartridge from being separated. A lock ring can be rotatable through an angle about a filter axis to selectively allow removal of the filter cartridge from the filter casing. The rotation of the lock ring can be through a small angle and the removal of the filter cartridge from the filter casing can be completed without rotation of the faucet, the filter cartridge, or the filter casing.
