The Pur FM-3700B is part of the water filter
test program at Consumer Reports. In our lab tests, water filter
models like the FM-3700B are rated on multiple criteria, such as those listed below.
Lead removal indicates the percentage of lead that was removed by each filter.
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 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.

I have purchased two of these units and have had the same issue with both. After a few months the plastic faucet adapter keeps popping off my faucet causing water to spray everywhere. I have tried everything from thread tape to cleaing the calcium from my faucet. I am ready to go to another brand.

Poor quality faucet adapter
Good water quality
Faucet Adapter Fails
The filter does a good job at producing good tasting water and the design is convenient with the faucet mount with the flip to switch between filtered water and non-filtered water. The filter life indicator is also a nice feature. The adapter to connect to the faucet is cheap plastic and fails too quickly, forcing you to buy a whole new system or throw away the cartridges and switch to a different brand. I would not recommend this product unless they improve the adapter design.
