3 What is an ion?
An ion is an atom or a group of atoms carrying an electric charge. Positively charged
ions are called positive ions and negatively charged ions are called negative ions.

How do negative ions clean the air?
Most particles in the air have a positive charge or are positively ionized, whereas neg-
ative ions have a negative charge. Negative ions bond with positively charged particles
by magnetic attraction. When the air contains a concentration of negative ions which is
high enough, it attracts high quantities of these suspended particles. The particles then
become too heavy to remain suspended in the air. As a result, the particles are removed
from the air, out of the breathing zone and the respiratory passages where they can
cause breathing difficulties and health problems.
Advantages of negative ions
•
Negative ions raise the oxygen flow.
•
Negative ions clean the air by removing smoke and particles from the air.
•
Air cleaned by negative ions leads to greater vigilance, less drowsiness and more
mental energy.
•
Negative ions lower the effects of depression, regulate sleep patterns and improve
air quality.
•
Negative ions can neutralize strong static attraction from TV sets and computer
screens and lower the harmful effects on the eyes.
•
Negative ions can completely neutralize any static attraction, e.g. when combing
hair, to make the air more pleasant and softer.
•
The negative ion function of the fan can remain switched on 24 hours a day. Nega-
tive ions contribute to a pleasant, healthy home climate and remove harmful particles
from the air. The negative ion function on the fan can be used, for example, in bed-
rooms, in particular in children's bedrooms, to achieve a positive healthy effect
