Yeah "water purity" is a grey zone, lots of scams. When I was young I earned some cash as a handyman. The stuff some people wanted me to install in their water system was baffling. Especially since I live in an european country with probably the best tap water quality in the world.
edit: just watched the vid, hillarious, they are just disolving the toxic metal particles in the water holy moly and use distilled non conductive water for the "proof". Yay humanity!

It might not be toxic.
Looked like steel, so you're primarily just producing iron oxide (rust) and dumping that into/onto the water. But also whatever else is alloyed into the steel. And I still wouldn't touch it.

Yeah, if it's stainless steel for example, you're getting some delicious chromium, which is a Bad Time.

Yeah, fuck chromium. I grew up in a town that had a chrome plating factory and they dumped their waste in the creek that ran alongside two schools. I was born with correctable heart defect but damn there were a lot of kids with cancer.

Nah, Northern California, Willits

Jersey City used to regularly turn some shade of purple because of the factory. Now there's a gated community in place of the factory.
The local wetlands preserve says not to eat the crabs in the water because you'll get cancer.

Been doing some home electrolysis for fun. Everything I read about chromium has me feeling like this.

Why would they want baffling installed in their water system? Was it really that noisy?

They wanted to pump it up
