Best Under-Sink Water Filters From Consumer Reports' Tests
These top-rated filters can keep clean water on tap in your home
Under-sink water filters can deliver cleaner, better-tasting drinking water the old-fashioned way: from a spout.
They’re more effective at removing lead, chlorine, and other contaminants than popular fridge filters and water filter pitchers. “And under-sink water filters are inherently more convenient than pitchers, with higher filter capacity,” says Richard Handel, the CR project leader who oversees our water filter lab. “There’s no need to pour water into a pitcher and wait. You just flip the lever and the filtered water flows."
You can buy them at major retailers or independent dealers. Of course, they do require installation and space under the sink. "And there’s a higher initial cost and cost per year, compared with water filter pitchers,” adds Handel.
