Fridge water filters are in every new fridge!
Ugh, I looked at new fridges and everyone had the water filter that needed to be replaced at least every six months. One had a filter that was $100 dollars and one had two filters. I wanted a fridge that didn't have the filter as I have a water filter in the water line going to the fridge we change out for $12 every six months. My fridge won't work without the filter! So check that out before buying a new fridge. Why have these filters? If people wanted filtered water then it should be an option. The filters are expensive and hard to find one that fits after a few years. The filter for my fridge started out to be about $40. Now it's over $70. DH cut the last fridge one we used for about a year it was clean as a whistle. The inline filter DH saws in half, other then contaminants we can't see that it claims to catch, that filter always looks clean too.
