Choosing an Under-Sink Filter System with a Kraus Sink
For new Kraus sink installations: select an under-sink filter system based on your primary water quality concern, then select a matching Kraus KFF filter faucet in your sink's finish. APEC ROES-50 + Kraus KFF (chrome or stainless, $50--$80) provides maximum RO filtration at moderate total cost. Waterdrop G3P800 + Kraus KFF (brushed nickel or black, $60--$100) provides tankless convenience with modern finish options. Aquasana Claryum Direct Connect (no dedicated faucet required) is the easiest install for existing Kraus sinks with no available hole for an additional faucet.
