I use this filter in our Kitchenaid refrigerator and it works fine.  I see where the prior review says there is a bad taste to the water coming out but we do not have that issue.  The water has no odd or remarkable taste or odor...it tastes and smells like plain water.  I've purchased two of these filters with no issues and will continue to buy them as needed.  I like that the filter removes quite a bit more from the water than cheaper alternatives...we'll keep this one around.
