Generally, tourmaline generates the same amount of positive and negative ions when pressure is applied to it.
While most of tourmaline products found in the market generate negative/positive ions simultaneously,
you can enjoy negative ion effects with those products as found on
Tourmalines' beneficial effects on health.
Negative ions are not all cancelled out by the same amount of positive ions.
You can observe that both ions exist separately with
the ion counter".
It is often said that negative ions do not work because positive ions are also generated.
However, as stated above, they are not always cancelled out.
Positive and negative ions can exist separately depending on the distance between them.
