Product review (1 stars): Low quality, poor filtering
Don't waste your money on this.  This filter only lasted 2 months, when the actual filters from either Whirlpool or Kenmore really last 6 months.  After 2 months with this Aquacrest filter, water started flowing at a significantly lower rate implying that it is clogged and no longer capable of true filtering.  With filters from either Whirlpool or Kenmore, this behavior typically isn't seen until the end of the 6th month.
