Buy these from Whirlpool instead.
August 20, 2022

VERY OVERPRICED compared to the same and more readily available Whirlpool filters the local Sears store had been carrying. With this and parts problems with our just out of warranty microwave, I doubt I will be purchasing from Sears Parts Direct or the local store again soon, if ever.

Unit died
February 21, 2021

The RO unit died as soon as all 3 filters were replaced as per the owners manual an as done many times in the past. Waste of an expensive RO filter as well as the pre & post filters. No water flow after change. Defective filters or bad timing?
