Consumer Reports Ratings for Best Water filters

Best Water filter for Flow rate

Flow rate is how fast a gallon of water filtered through the cartridge. The criteria for flow rate scores differ between different types of filters. Faucet-mount, countertop, and undersink models have the same criterion; carafes and reverse osmosis models each have their own.

Best Water filter for Lead removal

Lead removal indicates the percentage of lead that was removed by each filter.


This Water filter which tested best for Lead removal has the following features: Filter cost and Filter-life indicator.

Best Water filter for Clogging

This Water filter which tested best for Clogging has the following features: Filter cost and Filter-life indicator.

Best Water filter for Chloroform removal

Chloroform removal rates the percentage of chloroform removed. A filter's ability to remove chloroform predicts how well it will remove organic compounds as well as byproducts created by disinfectants used by water systems.


This Water filter which tested best for Chloroform removal has the following features: Filter cost and Filter-life indicator.
