Product review (5 stars): NSF rated, less sputter, worth the extra price over generic filters
These work very well and not that much sputtering water, unlike the one that came with the fridge and the discount filters sold by others on Amazon.  For instance, with the other filters, water would almost always sputter out of the spigot and can make a wet mess around the fridge and water dispenser area.  Rarely happens with this filter. Could it be the Whirlpool water pump causing sputter? Sure, but this one seems to reduce that occurrence.  I like that it is NSF rated to reduce numerous things from tap water, too.
