Product review (5 stars): Expensive, but protects against chemicals, not just dirt and microorganisms
I bought a house and inherited the fridge, a KitchenAid Superba, which needed a new water and ice filter. I usually go for high quality generic parts, believing that manufacturers can and do charge more for their brand recognition. Thus my first inclination was to buy cheaper, but highly rated filter replacements that are not endorsed by Whirlpool, but closer inspection showed that they don't protect against as many health threats as the EveryDrop. Look at the NSF ratings for each and you'll realize that the generic filters are simply using mechanical and activated charcoal filtration, which is sufficient for eliminating odor and most bad taste, but can still leave toxic chemicals in the water. My city had a water scare this past year, so I wasn't going to take a chance with a lower level of protection, especially as I have young children.

I'm not completely satisfied with the price, but until the other manufacturers improve their level of filtration, I'll continue to buy these.
