Product review (1 stars): Either wrong filter in box, or filter doesn't work in GE Refrigerator
My GE Refrigerator takes a MWF filter but this filter didn't easily fit into the hole. It had no arrow to line up, but even when lined up perfectly it still didn't really fit Managed to get it in only to find no water would flow through it. (Yes I filled it in the sink and ran water through it a little myself.) Tried several times, simply doesn't work. Had to put old filter back in place until I get a replacement from another company.

Note the outside box matched what is being sold here but the filter inside had a different number on it and also all instructions on the sticker were in a different language, I believe Spanish.

Note- I ordered this replacement back in February 2015, but I didn't actually try to use it until today (January 2016) - it sat untouched in the original box while I used up other filters I had.
