Kenmore Single Undersink Drinking Water System —
This filter comes highly rated by Consumer Reports and is inexpensive. We have found that this filter very effectively removes chlorine and off tastes from our water. This unit was not trivial to install, but I completed in in about 30 minutes. I did it using the included hardware, but my sink already had an existing hole so I didn't have to drill one. Once installed, it is very convienent to use. It's now been working for 9 months with no problems.
