This brand was WAY less expensive than the Samsung brand (that's the fridge) that was in already when we bought the new house. We could order so many more! You should change the filter regularly. The only thing that I don't like is that they create so much garbage for the landfills. Has anyone figured out how to make these filters recyclable? I know that clean water is very important, but still, these won't break down ever. We have a well which was tested and the water is fine, so don't even need to use the machine on the fridge. When this one goes, I won't buy one with a water machine anyway.
