A while ago we had a whole house water filter installed, and I've let it go a bit too long before replacing the cartridge. Now I want to, but there are no markings on the filter housing to help me select a replacement. I shut the water off and removed the old cartridge. It is 9.5" tall and 3" in diameter. I see a lot of cartridges on Amazon that are 10 x 2.5. Is that a match?
