Product review (4 stars): It's a filter.
What can I say. Not much choice to replace my GE filter ... with another GE filter. It works well only for about 8 months then you're supposed to buy another. The cost is outrageous...$35. I would love to try the generic filters but maybe they won't work and I will have wasted more money. So I, like probably most people, just reset the red warning light and use the filter as long as I can ... until the water flow begins to slow. Probably not that healthy but economical!! lol  I don't see why it has to cost so much. Another GE product!
