Product review (4 stars): Good Choice
this product shipped quickly and installed easily.  There were no instructions but having done this every 6 months for the last 4 years I knew that was a requirement.  I flushed the loose carbon particles with about 1 pint of water instead of the 2 to 3 quarts that other filters have required.  The last one I bought was cheaper but it leaked a little and I will not buy that brand again.  I do not have any way of testing water filtration but the water tastes good so it appears to be working as advertised.
