Actually the oldest for filler would be DragonBall Z for its training arc throughout the series. And the longest filler arc just to arrive back to the same point would be Naruto for its 1000 episodes filler arc. But yea, it is annoying but is the reason why I said the anime will never be ahead of the Manga even though it has a light novel source. High-school DxD and DATE-a-live are example of the anime will not but ahead of the Manga or light novel.
