Product review (2 stars): Overpriced.
My refrigerator has a light that comes up when I have to replace this air filter. I thought this filter was a bit more complex. This filter is just a square  activated carbon waffer sandwiched between two dryer sheets.
I find it to be extremely overpriced. Too bad there is not a generic version of this filter.

Next time I have to replace it, I'll just take it out and put a fresh box of baking soda.
