is bleach episode 350 filler?

Following his bad feelings in regards to Orihime Inoue, Yasutora Sado and Ichigo Kurosaki begin rushing towards her house, running the entire way. Whilst running, Ichigo takes out his phone and Sado asks him what who he is calling.

Ichigo responds that he is trying to contact Orihime of course, to see if she is alright. However, Sado reminds him that Orihime is not alone and that the moment she hears her ringtone might provide an opening for her opponent to attack.

Ichigo asks if the situation is really that bad, but Sado replies that he doesn't know, all he's aware of is that Orihime's Reiatsu is currently under a lot of strain.
