I had ordered one for my beverage center. It worked great.

The next time I needed it I actually called the company to ask a few questions  he said contrary to what some of the other reviews say it's not a necessary evil  it's only to keep the air fresh it will not hurt the refrigerator if you don't get it. With that said, my beverage center is the small refrigerator for beer pop and maybe some small other items it is not a big refrigerator which might benefit from the filter as to not collect orders in the fridge. Now a water filter is definitely necessary.
