My filter is very old, so I guess they last years but not forever. The strange thing is it broke by itself. I only noticed the filter kept gurgling bubbles and only checked the impeller because the filter wouldn't restart after a water change.
My old internal filters have metal ones and have been working relentlessly for years so it's a bit subjective what's best.
