Product review (1 stars): an unwanted substitution.
Junk.
I didn't buy this intentionally. It was a replacement for the filter I normally purchase through Amazon's subscription service. I didn't think too much of the substitution at first but we've only had it for about 2 months and the thing is already shot. The old brand lasted 6 months and the water tasted better than it does with this new brand. I know that's subjective but it's true.
I cancelled my subscription and am searching for a better replacement.
