The Culligan FM-15A is part of the Water filter test program at Consumer Reports. In our lab tests, Water filter models like the FM-15A are rated on multiple criteria, such as those listed below.
Lead removal: Lead removal indicates the percentage of lead that was removed by each filter.
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.
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.
Unbiased: Retailers cannot influence placement.
Ad-free: As an integrated part of Consumer Reports, you shop in a completely ad-free environment.
New products only: You will never find used or refurbished products for sale.
