is bleach episode 335 filler?

Lying helplessly in the rain as Kagerōza Inaba takes Nozomi Kujō away, Ichigo blacks out. Later, he awakens at the Urahara Shop, Urahara having brought him there.

As Urahara tells him he has not been out too long - maybe half a day after he had passed out - Ichigo asks how the others are doing. Urahara states they have not fully recovered just yet, but are getting better slowly, due to the efforts of Orihime Inoue.

Asking Ichigo to focus on making a full recovery, Urahara begins to leave the room to make Ichigo some tea. When Ichigo asks if he had lost all of his Reiatsu, Urahara states he did.
