Product review (1 stars): Doesn't work properly
Does not replace Whirlpool Filter 4 in my Whirlpool fridge.  Bought a 2 pack and both created grinding noises and allowed little to no water to pass through.  Wrote the company and they said it doesn't support my fridge, but my fridge takes Filter 4, so no idea how that makes any sense.  Have been offered a refund but must pay for shipping back, so lost at least the amount to ship back the thing (which I expect to cost a few dollars). Waste of time and money.
