Product review (1 stars): Now with Water Discoloration Feature at No Extra Cost!!
As others have noted, this filter has poor fit on my older model Whirlpool for which it is a designated repalcement part. More disconcerting was the blue-gray coloring in the water and ice cubes the day after installation. If it were just about saving money, I'd drink feom the tap. If it's clean water you're after, I recommend undertaking the aggravating search for the new OEM replacement, branded as Everydrop.

(Accompanying photo is evenly-lit in sunlight and shows an ice cube before the filter was installed above an ice cube after the water from the filter had reached the icemaker.)
