The Culligan ZeroWater pitcher ranked second in our testing with an impressive overall score of 9.33 out of 10.

This gravity-fed pitcher uses a 5-stage filtration system that combines mechanical filtration, activated carbon, KDF, and mixed-bed ion exchange resin to reduce a wide range of contaminants.

One of the biggest advantages is flexibility. The same certified filtration technology is available in multiple sizes, from a compact 7-cup pitcher to a large 40-cup glass dispenser.

Watch to see why the ZeroWater pitcher performed so well and whether it's the right fit for your home.
