Fairy Tail fillers fillers were first introduced to prevent the series from reaching the Manga, a common practice in animes that are adapted from a Manga source. If you include some sub-canon episodes that run like fillers, there are about 68 episodes of filler content in Fairy Tail.
The best Fairy Tail filler episodes are the infinity clock arc (Ep. 128-150) and the celestial spirits battles (Ep. 205-218). Make sure you also check out the sub-canons in Ep. 20, 151, 255, 279, and 312.
Can you skip Fairy Tail fillers? Yes, you can skip Fairy Tail fillers because these fillers do not really change the overall arc of the story and characters’ development. However, some fillers do add more depth and detail to the show’s dynamics, so I recommend watching them all.

Is The Fairy Tail Filler Arc Worth Watching?
The Fairy Tail fillers by themselves don’t follow a strict arc of the main story. But they can often act as extensions to existing episodes. For instance, you often find more details about specific magic or explanations that help you understand the actual episodes better.
