Abstract
A filtration cartridge faucet assembly contains a filtration cartridge having a filter core that is concealed beneath a sink deck through the use of an escutcheon mount. The escutcheon mount permits access to a renewable filtration cartridge from above the sink deck while concealing and protecting the filtration body. The renewable filtration cartridge is equipped with a flow control device, as well as counter rotation devices that prevent undesirable outrotation of a threaded cap.
