Product review (1 stars): I absolutely do not recommend these filters
This is the first time buying non-branded filters for our Kitchen Aid, and I won't buy these ever again. They impeded the flow of water so badly that there was a rattling/knocking sound behind the refrigerator. I tried not one, but two with the same results (the third one was tossed out immediately). The repair man said he thought we might have to replace the filter interface (where the filter installs inside the fridge)  = $$. As luck would have it, I found a spare branded-filter in the back of the cabinet, put it in, and voila! no more rattling sound. Water flowed freely and problem solved. I absolutely do not recommend these filters.
