Healthcare benefits of negative ions

Negative ion air purifier is also be called as air ionizer, ionic air purifier or anion air purifier. The treatment with negative ions has many advantages. Some of these health-enhancing effects of negative ions are:

• Removal of bacteria from the air and therefore reduced inhalation of allergens

• Activation of somatic cells

• Rise in the blood’s oxygen uptake

• Increase of alpha waves within the brain

• Improvement of the metabolism

• Decrease of fatigue, headache, tension, constipation, allergies and asthma

• Anxieties and depression can be reduced or completely dissolved

• More effective disease resistance

What’s negative ion air purifier?

Negative ion air purifier is also be called as air ionizer, ionic air purifier or anion air purifier.

We Trume specializes in the core component of air ionizers, namely negative ion generators. And, we have a variety of air ionizers, which are used in person, computor, car, home, office, etc.

Our air purifiers integrate negative ions with ozone, HEPA & active carbon filters. The combination of the functions will effectively purify air.


What role does negative ion play?

Negative ions attach themselves to harmful positively charged atoms (pollutants, allergens). Therefore, the newly formed, bigger particles drop to the ground and can not be inhaled anymore. The pollutants get neutralised due to the influence of the negative ions.


Scientific evidence of negative ions’ healthcare benefits

There is a variety of scientific studies proving the positive effect of negative ions on human health. Negative ions By now there is scientific evidence that negative ions increase alpha brain waves and their amplitudes which causes a higher level of consciousness. Alpha waves induced by negative ions run from the back of the head to the parietal bone and temples and even reach the frontal lobe by commonly spreading across the left and right hemisphere. This creates an overall calming effect. Among the physical benefits are relief of asthma, migraine, burns and post-surgical pain. In accordance with the relief of burns they soothe inflammations and lower the duration of burns and risk for scars.

“Generally speaking, negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy,” says Pierce J. Howard, PhD, author of The Owners Manual for the Brain: Everyday Applications from Mind Brain Research and director of research at the Center for Applied Cognitive Sciences in Charlotte , N.C.

A variety of research with kindergartens and schools has shown impressive results: one year after the installation of a negative ion generator in classrooms educators reported that their pupils could concentrate better and suffered less under the weather. Children with ADHD behaved calmer and the teachers themselves felt less exhausted. This results came from a recent study conducted by Mijeco GmbH in collaboration with the Balance Therapy Clinic in Sydney. Through the use of the Mijeco Negative Ions Generator, Eco-Living, the exhaustion of participants was reduced by 38% after 5 minutes while their level of alertness increased by 100%.

There are many theories on why negative ions induce euphoria while positive ions cause depression. A popular theory states that negative ions can move freely throughout the body. since a

negative ion carries an additional electron, the motion of a negative ion is the same as the motion of an electron. Quick moving electrons cause a massage on the molecular level and dissolve blockages within the body. Positive ions are molecules that miss an electron. They generate an electric field but the motion of an “electron hole” is slow. They generate tension that is dissolved

slowly by the ion’s motion (electron hole).

A study on prevention of seasonal depression with negative ions shows amazing results. 25 people suffering from winter depression took part in a controlled double-blind study with negative ions. The subjects were exposed to two different density levels of negative ions. 10.000 ions per cubic centimeter (low density) or 2.700.000 ions per cubic centimeter (high density) A radiator of corona wire was used as an electronic generator to transmit the negative ions. With periods of remission of 50% or a higher reduction of the symptom-frequency/strength, the results were the following: 58% of the subjects showed a reaction to the treatment with a high density of negative ions and 15% of the subjects showed a reaction to the treatment with a low density of ions.


A recently conducted study of the U.S. Department of Agriculture has shown that the ionisation of a room leads to 52% less dust and 95% less air-borne bacteria (because many air-borne pollutants

cling to floating dust motes). Negative ions are also recognised by the U.S. FDA (Food and Drug

Administration) as a measure of allergy treatment. Many European, American and Russian hospitals already use generators for ionisation, as the positive effects of negative ions to physical wellbeing are indisputable. Ionisation machines free the air in hospitals of dangerous germs.
