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.

Is there anything else that they say the filters have trouble with, like Chlorine levels? It could be the city/county is randomly pushing thru too much on the the line.... I know RI is notorious for water problems in various areas and random 'Boil only' rules because of contaminations that get into the system.

Maybe the problem is because we have a coil hot water system, instead of a tank.
I had no idea that RI water was notoriously bad!

About the DuPont
"CAUTION: Cartridge Prone to Premature The filter cartridge that goes in this unit is a defective product prone to preRupturing, January 23, 2009
By yojimbo (wash, dc) - See all my reviews
You're lucky if this lasts 50 gallons b/c the Dupont FMC300 is prone to premature rupturing, likely due to a manufacturing/design defect. The bottom seam/weld of the cartridge is very weak and will not last anywhere near the 200 gallons of life it's rated for. I have gone through three FMC300 cartridges (rated for 200 gallons) but in fact each lasted less than 50 gallons of use. The first sign of trouble is usually a slow drip from somewhere around filter unit; eventually it deteriorates into a gushing fountain.
Dupont Customer Service is aware of the problem with this cartridge, as well as the FMC103 rated for 100 gallons. The construction is the same, and they both have the same defective bottom panel seam/weld. If you call to ask for a replacement of a leaky faucet filter unit they will demand a dated sales receipt, etc. But if you tell them you have a defective, 'ruptured cartridge' then they will offer you a replacement, no questions asked. Obviously, they know the FMC300 cartridge is a defective product."
Re: About the DuPont
Maybe the problem isn't that hot water is flowing through the filter, though. Maybe the filter is just heated up too much when I turn on the unfiltered hot water?
The thing is, we've seen this same problem with several different brands of faucet filters, so something is definitely wrong!
