My parents have a two stage filter where one stage is for the sump and the other is for that charcoal cartridge. Instead I installed two charcoal cartridges like this and no mud cartridge. Now it obviously filters out the sediment, but being dual carbon it gives me a water quality I just blew away that comes very close to my reverse osmosis water in taste and clean feel! I love the dual water cartridges these have to offer, it's absolutely amazing and using all the charcoal in both phases is a great way to improve the quality of the water you get! Tested and verified!
