[Summary] The most important factor
Negative ions have to reach you!
There are several factors to consider when choosing the right negative ion generator. The most important factor is if negative ions reach you or not.
However, many manufacturers do not provide this most important information.
Negative ion count information in the blow off and angled directions shows you if the negative ions reach you.
For example, "Massive negative ions!" or "2,000,000 pcs negative ions!" does not ensure that the negative ions reach you.
Coverage areas are just for your reference only because there is no industry standard.
We suggest you should make sure that the negative ions will reach you before you purchase the product.
