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 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.
How long have you owned it:
A month or less
No, I would not recommend this to a friend.

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.
How long have you owned it:
More than six months
Yes, I would recommend this to a friend.

Faucet Adapter is JUNK
Used for years and USED to be a good product, the filtered water may still be OK, but the adapters LEAK and therefore I am abandoning this product. <br /><br /> ConsumerReports (via their high recommendation, in light of numerous complaints here and elsewhere) does not listen to it's subscribers NOR does PUR/KAZ and it's customers. They just keep on failing to be effective and YOU can not make them care.<br /><br />Stop spending and see who notices...
