This is a component removed by a contractor during a kitchen remodel. It's an older model of a currently sold product (the only difference is the shape of the filter attachment), but the performance is exactly the same. It was stored under the sink, so it's clean. It comes with the original dedicated hook for hanging the water purifier on the back panel of the kitchen. I'm offering it to someone who can use it, as I've installed a new water purifier. Compatible cartridge: RS-1SGE The water purifier cartridge, hose, and faucet are not included, so please prepare them yourself. There is a white protective cover on the joint.
