Product review (5 stars): Just as good as the Whirlpool filters
I have purchased this product several times from this vendor.  This vendor is responsive and I usually have my filter in 48 hours or less.  The filter fits my Kitchenaid refrigerator perfectly and requires 30 seconds to uninstall the old one and then reinstall the new one.  Based upon our water usage (which is a lot), the filter usually lasts about 9 months - 1 year before the control board tells me to change it.  I have also used test strips to verify the quality of the water coming out of my refrigerator (post filtration) and there is no doubt this filter does what its suppose to do.
