Product review (2 stars): Well, these filters ARE cheaper than the real ones ...
Well, these filters ARE cheaper than the real ones and right out the packaging you can feel they are lighter, but they don't quite seem to filter out things quite as well as the original.  How can I tell - well the water still has a flavor to it.  When using the real filters the water comes out tasteless and doesn't develop a taste until the filter has passed its usefulness.  With THESE filters there is a flavor from day one.

We ended up just using the water from the fridge for ice, and then buying bottled water before finally upgrading to a Whirlpool Water Cooler.
