Cheers + good luck! If you do end up with an undersink filtration system, I’ll offer to bits of advice: 1. Having a separate faucet AND the fridge / icemaker dispenser is awesome and 2. Watch what you buy. An off the shelf system from Home Depot may or may not be good at filtering lead. It’s surprising — seemingly identical GE systems (e.g.) could be great or mediocre, with no rhyme or reason. So read the specs … and consider filter replacement cost. We went with the Pentek US-1500 / Culligan SY-2650 / American Plumber WLCS-1000. They’re all the same housing (?!), but the Pentek has a flow meter to tell you when to replace the filter … and is cheaper. There’s a writeup in consumer reports a year or two ago.
