These are great for the whole-house system

These are great filters though ours only last a month or so because our water (coming in) is pretty bad. We get sediments as well as rust and clorine from an old city water system. These make the water nice and clear odor free and they protect the filter on the fridge so that it lasts 6 months or more like it should.
A great product and an excellent value.
