Umm, a water filter is mostly a reservoir, tubing, and a pile of chemical reactants. This is not planned obsolescence. This is just pure chemistry. The reactants become saturated and need replacing.
All water filtration systems require periodic changing of filters.
That said, there are many stage filtration systems, and you don't need most of them. A three-stage reverse osmosis system will give you the cleanest water possible. Like mine was a 4 stage with a final remineralization step that I just didn't hook up.
If you want to understand it better watch this [1], just skip the deionization step because drinking deionized water is very unhealthy.
