Actually Boruto anime does have filler episodes. If you want to know which episodes are not canon, there is a simple solution. Well, foremost, don't trust such fansites.

Essentially, every single scene/event/episode NOT adapted into the Boruto anime novelization is not canon. So if something is in the anime but not in the novel retelling of the anime, it's filler content.
