Product review (5 stars): whenever the water started tasting bad, I went to Sears and bought another Water ...
I have an Amana refrigerator with a built in ice maker. In the past, whenever the water started tasting bad, I went to Sears and bought another Water Filtration System Replacement Cartridge, Replacement Cartridge Part No. WF401S, Model WF40 for $65.00 each. Recently, when I tried to purchase a new filter, they told me they no longer sold the filter, and that I should try to find it online. They also advised me to cut my water line behind the fridge and install an inline filter. I found one for $65, but I also found this Waterdrop WF401, which claimed to be compatible. I purchased one. I figured for $9.95 I could throw it away, if it did not suit my needs. It worked perfectly, so I bought 3 more to keep on hand in case this company stops making them, too. I figure Amana probably had a Chinese company build their WF401S, and the maker of this unit simply modified their design and started selling it for far less. It's hard to feel sorry for a company that moves all its manufacturing out of the country to save money and then charges an outrageous price for the foreign made product.
