Product review (4 stars): Cheap knock-offs might be OK for your printer-cartridges...but this filter-cartridge is for your DRINKING water.
After becoming exasperated and disgusted by what appears to be cheaper, poor-quality replacement filters of questionable quality and questionable reviews here on Amazon -- coupled with the fact that the old PUR-filters were replaced by Whirlpool with these newer-filters, I decided to give one a try.  Flushed with 4-gallons as instructed.  I detected no strange taste, unlike some (perhaps questionable) reviews.  I note that this EveryDrop filter is made by the same manufacturing facility in Taiwan as the old-style PUR-filters to the NSF-testing-standards -- and is the fridge manufacturer's replacement.  A bit pricey -- but that is what the knock-off filters are playing upon.... Cheap knock-offs might be OK for your printer-cartridges...but this filter is for water YOU DRINK.  Will now consider purchasing annually with Subscribe-and-Save in bulk to hold down the unit costs...
