eSpring 100188 Water Filter Report

The eSpring® Water Purifier improves the taste, odor, and clarity of 1,320 gallons of water, enough for a family of six to cook and drink with, for one year. eSpring claims it is the first in-home system to combine ultraviolet light technology with a multi-stage carbon-block filter.

The carbon-block filter reduces more than 140 potential health-effect contaminants – like pesticides, VOCs, mercury, and lead – yet allows beneficial minerals like calcium and magnesium to pass through.

The UV bulb destroys microorganisms in drinking water without the use of chemicals. eSpring is certified by NSF International and has earned a Gold Seal from the Water Quality Association.
