Product review (5 stars): These filters are as good, if not better than the manufacturer brand.
I have been purchasing replacement filters for my fridge for about 5 years now and never have a problem with them not being from the manufacturer. Because I order a set of 2 or more at a time by the time I order more I may see different alternate brands. This was my first time buying these Tier 1's and they work great. Definitely works just as well as the manufacturer brand. Water is clean and clear and tastes good. Would definitely purchase again.
