Are Hollows defeated by humans who are not Quincies considered as destroyed or "purified"? If I remember correctly, Shinigami are "purifying" Hollows with Zanpakuto, cleansing souls and sending them to Soul Society (not counting cases when souls are going to Hell). And regarding Quincy, it was said that the main conflict between Quincies and Shinigami was that, unlike Shinigami, Quincies were destroying souls when killing Hollows, which was bad for balance.

In series, it was shown numerous times that Hollows can also be defeated by humans having certain abilities, for example, Yasutora Sado, Orihime Inoue, Hanakari Jinta, etc. So, what happens with Hollow soul in this case? Is it exorcised, or destroyed, just like by Quincy hand?
If killed by a Soul Reaper they go to Soul Society if they were actually good, so only the bad ones go to Hell. Quincy destroy them completely. Humans just kill them and send them to Hell. Only Soul Reapers purify them.



Not a source, but I watched all episodes of Bleach and finished the manga. At one point they are talking about how Chad's or Orihime's powers are special. Chad said something about his spiritual pressure doing something when he went to Hueco Mundo, and Hachigan was a Soul Reaper/Vizard with Orihime's power.

Captain Kurotsuchi also said it when he realized the Quincy were invading.
