The whole "negative ions" pseudoscience nonsense needs to stop. These stupid "negative ion" health machines do no such thing. I read the description for a salt crystal lamp that supposedly fills the air with "negative ions", and as far as I can tell, these folks don't even know what an ion is.

It is a fundamental property of matter that you can't have sustained long range charge separation without something keeping the charges apart, like the insulator of a capacitor. If that fan really ionized the air, I'd be worried; ionizing radiation (like UV rays and gamma rays) are not good for your health. And in the process of filling the air with negative ions, it would also fill the air with positive ions, which would then recombine with the negative ions, and negate the whole effect.

I hate it when hucksters think they can tack "health" and some scientific terms nobody (including themselves) understands, and make an extra buck because some sucker thinks his product is somehow better for his health. Unfortunately, the ignorance of the general populace lets it happen.
