is bleach episode 162 filler?

With Ichigo Kurosaki activating his Bankai, Tensa Zangetsu, and leaping out of the resulting surge of Reiatsu as its shockwave washes over the hallway, an initially unfazed Ulquiorra Cifer is startled to see Ichigo wearing his Hollow mask just before the latter unleashes a powerful burst of Reiatsu that slams into Ulquiorra just before Ichigo travels through it and comes down on Ulquiorra with a Reiatsu-infused strike of his sword, forcing an unnerved Ulquiorra to block this with his hand.
