Our countertop drinking water filter offers Aquasana’s unbeatable drinking water filtration technology in a convenient, portable package. There’s no need for an extra hole in your sink to enjoy healthy, filtered water. Simply attach our diverter to your existing tap, and the countertop filtration unit takes up just a small space on your counter. And with three color options to choose from, you can match your kitchen style.

This unique twin cartridge system uses a combination of carbon filtration, ion exchange and sub-micron filtration. Your tap water is forced under pressure over filtration material covering more than two million square feet of surface area, so it removes over three times more contaminants than leading pitcher filters. The Aquasana water filtration system is uniquely designed to remove pollutants, reduce odor, and improve taste while preserving healthy minerals for optimum hydration.
