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.

Ease of Use
Too Side Heavy
I have used PUR sucessfully in the past. I have had the same reviewer reported poor results with the new 1-click system. Severe leaking from the adapter seams. Unit has fallen off the faucet. I have contacted KAZ numerous times. I received replacement adapters that still leak at the same place. I have exchanged 2 units. I will try the garden hose adapter suggestion from a reviewer before I throw in the towel.

Hard to keep on faucet but found a fix.
Good Water Taste
Not Enough Threads
This unit does not have enough threads and is too heavy when filled with water so it often came off during use. My husband solved this by attaching a 55/64 garden hose aerator adapter.
