Product review (3 stars): This non-OEM model fit our Whirlpool refrigerator nicely. After flushing 5 gallons
This non-OEM model fit our Whirlpool refrigerator nicely.  After flushing 5 gallons, the water was tested with a TDS meter.  Result was 290 PPM.  Water out of the tap is 320 PPM.  The difference in taste and PPM was not enough to justify using this filter.  The expired OEM version tested at 250 PPM.
