Forespar’s PureWater+ potable water filtration system has a patented quick-connect design that allows for filter changes above the countertop. With a quarter-turn of the faucet, the carbon filter lifts out and slips off for replacement. PureWater+ is ideal for installations where space is at a premium. The system comes with a chrome faucet, installation hardware and two carbon-block filters (0.5 and 5 microns). $190. Forespar Products, Rancho Santa Margarita, California, (949) 858-8820.
