Product review (3 stars): Good filters, I have used just one so far ...
Good filters, I have used just one so far and I notice that the water tasted great when I first installed one, but after only three months I may need to change it again, because the water just does't taste as good any more, so I can't help but wonder if I'm getting a concentration of what was in the water when I first installed it?  If it's just my imagination, then why doesn't the water taste as good as it first did?
I think I read that you need to change it after 240 gallons of use, which includes the ice maker, this is a refrigerator filter, who keeps track of the gallons used?
