It's almost pure carbon, it does in fact absorb some waterborne impurities. (not that I would trust it over modern filtration/sterilizatiom).

Shungite has been used as a folk medical treatment since the early 18th century. Peter the Great set up Russia's first spa in Karelia to make use of the water purifying properties of shungite, which he had himself experienced. He also instigated its use in providing purified water for the Russian army. The anti-bacterial properties of shungite have been confirmed by modern testing.

"EMF protection"...not so much. These nutters need to all be put in a giant farady cage and wonder why "my phone don't work".

Kinda like that doohickey that is supposedly using a 100k rpm motor.... lol

There are plenty of 100k rpm motors out there, it seems. (But that will be without load, I guess.)
Xiaomi is in most cases a rather innovative company and one of the more trustworthy chinese companies.
So I'd say it's quite possible they put such a motor in there.

This Aliexpress offer has some Details on such a motor:
