Bought these backup filters for my refrigreater about six months ago. In that time, my refrigerator went out and My new refrigerator requires different size water filters.
All three are brand new and never been opened. Still has the instruction booklet and labels as seen in pictures. Also, I included a picture from Amazon. From what I can see. They go for about 15 a unit. So hopefully you can save some money, And I can make a little bit of my money back.
