Product review (5 stars): You can use a non-manufacturer filter and get good results
These work just as well as the name-brand product that Sears sells for my Kenmore side-by-side fridge/freezer. There they cost about $40 every six months; I've bought this brand of filter over the last year; this time they were bundled as 2 for what I paid for 1. I bought a year's supply of filters for a fraction of the cost of the store brand filters.
