Product review (3 stars): EveryDrop by Whirlpool Water EDR1RXD3 Filter 1 - Why do these filters have to be so damn expensive?
I ponied up extra to buy this more expensive EDR1RXD3 filter, replacement model for original Whirlpool W10295370 Refrigerator Water Filter.  W10295370 filter can be had here on Amazon and other sites for a lot less money but unsubstantiated claims of fakes being sold has tainted my feelings about purchasing them.  Single pack of this filter is $50, a princely sum for sure when compared to the cost of generic in-line filters.

As for this model, it works just like the original filter.  After flushing out the line of carbon residue, water tastes fine.  These filters are easier to access and replace than having to splice the water line in the back of the fridge and McGyvering a generic in-line filter, although this method is much, much cheaper.  Took off 2 stars for high price; the filter seems to work fine.
