An ion is negative if it has more electrons than protons. Negative ions, also known as anions, can have various positive effects, such as improving air quality.
These ions are more abundant in forests, by the sea and on mountains and can be particularly helpful in the home due to their ability to reduce free radicals.
In addition to their air-improving properties, they are also said to have a positive effect on the state of mind. ¹

However, many different service providers, particularly in the air purification sector, warn against the opposite of negative ions. The positive ions. Without negative ions in the air, positive ions could accumulate in our bodies. ²⠀
An abstinence of negative ions and an excess of positive ions can lead to a whole range of disadvantages that can be detrimental to our well-being. ³
Negative ions
Pierce J. Howard, PhD, author of "The Owner's Manual for the Brain: Everyday Applications from Mind-Brain research" and research director of the Center for Applied Cognitive Science in Charlotte, N.C., speaks positively about negative ions, referring in particular to their effects on the ability to concentrate.
Negative ions are also capable of improving air quality. A large number of air purifiers (ionizers) make use of this principle, as negative ions can attach themselves to almost invisible particles suspended in the air, for example, and make them so heavy that they sink to the ground and can no longer be inhaled.
The reasons for an artificial supply of negative ions are therefore manifold. Especially when you realize how few of these ions can be found in our own four walls. At original sources such as waterfalls, there are still 30,000-80,000 anions/cm³. On the outskirts of cities and in fields and meadows there are still 1,000-3,000, while in our own four walls, even ventilated and air-conditioned, there are only 10-100 anions per cm³.
For our well-being, however, at least 400 to 1000 negative ions per cm³ would be advisable and even more negative ions would be optimal.
The crystal mat from VITORI® generates as many as 7000 negative ions per cm³ and thus provides an abundance of anions in the air that is otherwise only found in mountain or sea air.
