About - Aquasana AQ-4000

The Aquasana AQ-4000 is part of the water filter test program at Consumer Reports. In our lab tests, water filter models like the AQ-4000 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.
