The ZeroWater Filtration Pitcher boasts a five-stage filtration system (including an “ion-exchange array,” which it doesn’t define) and holds a half-gallon of water. It retails for about $35 and has a display that shows the filter is working and when it needs replacing. ZeroWater’s pitcher has a push-button dispenser for the refrigerator and a pour spout for the table.

ZeroWater offers a filtered dispenser that replaces large plastic bottle dispensers.

A filter only lives through about 25 gallons of water, and replacement filters aren’t cheap at $30 for a two-pack. It comes with a stick-like meter that measures the total dissolved solids in the water.

ZeroWater’s filter removes fluoride, and the company says the filter is not certified to reduce microbiological cysts, as some other pitcher-makers say they can. It does remove all detectable dissolved solids, ZeroWater says.

ZeroWater recycles its filters, and its pitchers contain no BPAs. The company states that there are no established protocols to determine whether any pitcher filter can remove pharmaceuticals.

Its slick, larger version is actually a bottle filtration system that you place atop a bottled water dispenser. Fill it with tap water using a pitcher (no more expensive, big, heavy bottles to heft on the dispenser). This larger bottle has two filters to handle more water and costs about $80.
