E-9320 carbon water filter (1/90) 13 high-volume filters were tested, and the Amway E-9230 was among the 4 filters given the highest rating by CR. It was also the second most expensive, and at $276 was almost twice the cost of the also top-rated Sears 34201. CR noted that the cartridge on the Amway unit was "more difficult to replace than most," and at $69 was 2 to 3 times the cost of the cartridges for the other units.

At a distributor cost of about $231, including shipping, the E-9230 is less expensive than all but one of the other three top-rated units, but the cartridges are still far more expensive.
