Not well versed in the field, what are the basic implications of this for health?

In the 1970s there was a lot of talk about ‘healthful negative ions’ and a fad for negative ion generators even though many of those also generated hazardous ozone.

Hydroxyl ions are a significant kind of negative ion in the atmosphere and they’re known to be good because they react with and clean out pollutants like methane

How can something be a negative ion generator without simultaneously being a positive ion generator?

That isn't how chemistry works.

Isosaccharinic acid has the same chemical formula (C6H12O6) as glucose, which isn't acidic. However, they both have the same net charge.

When something is an acid, it dissociates into both a positive ion H+ and negative ion (rest of the molecule)

HA ⇌ H+ + A-
