Product review (1 stars): Tier 1 RWF1040 refrigerator  water filter for Maytag.
Slows down the water flow to fill a glass of water to more than double the time that of the Maytag & Pur filters, also purifies only half the amount of water as the Maytag filter therefore  have to change more frequently. Because of the diminished water flow the ice maker  makes very small ice cubes. My opinion,  not worth the money.  Go with PRU or Maytag.
