Water filter
I give up. The DuPont faucet filter had the same problems that all the other ones did; roughly one out of four filters worked properly, and the rest lasted a week or less.
Our water is NOT hard or particularly bad. So my best guess is that hot water is occasionally feeding into the cold water, and thereby ruining the filters.
So this weekend we bought a Brita dispenser, one of the big ones with a tap in the front, and put it in the refrigerator. We'll see how it works out. I'm going to fill it by filling up a pitcher and then pouring that water into the dispenser; that way if there's a surge of hot water, it will never reach the filter (the heat being moderated by being mixed with all the water in the pitcher first). Also, the filter itself will be cooler because it's in the refrigerator!
Unfortunately the Brita filter apparently doesn't filter anywhere near as much stuff as the DuPont did, but we can't afford to buy new filters every week.
