it seems that they should be changed yearly. however, i haven’t changed mine for a while. the water still taste good.
so i wonder if it is necessary to change every year at all?

change it every year like you do the battery in your smoke and fire detector.
The best is to change filters when you can tell there is a change in volume you receive.the quality wont go down the quantity will.
