Negative Ions Articles and Studies
Information on Negative Ions and the
Benefits of Negative Ions to Our Health
There are many benefits of Negative Ions stemming from the fact that
negative ions attach themselves to airborne particles such as dust, pollen,
smoke and dander, causing them to drop from the air. Because the air
is free of these allergens, many people notice that it is easier to breathe.
For more information on negative ions and the benefits of negative ions
to our health, the following information is presented:
Negative Ion Studies
Studies Proving the Effectiveness of Negative Ion Generators, U.S. Dept.
of Agriculture - A recent study by the U.S. Dept. of Agriculture found
that ionizing a room led to 52% less dust in the air, and 95% less bacteria
in the air (since many of the pollutants found in the air reside on floating
dust particles).
The U.S.D.A. also performed another study to test the effectiveness
of negative ionization at removing airborne Salmonella Enteritidis. The
negative ions drastically reduced the airborne salmonella particles,
prompting the following statement from the USDA:
"These results indicate that negative air ionization can have
a significant impact on the airborne microbial load in a poultry house
and at least a portion of this effect is through direct killing of
the organisms." (Summary
of Study from USDA Website)
Good Housekeeping Magazine - In March of 1999, Good Housekeeping Magazine
had its engineers test an ionizer by using a smoke test, and found that
it cleared out the smoke in a tank.
Agriculture Research Service (of USDA) - The Agriculture Research Service
of the U.S. Dept. of Agriculture tested the effectiveness of ionizers
for removing dust in a poultry hatchery. The dust level is very high
in such an environment. In this study, the use of an ionizer resulted
in dust removal efficiencies that averaged between 81.1 and 92.2%. The
airborne transmission of salmonella (to the eggs) was also significantly
reduced as a result. (Summary
of Study)
Journal of Hygiene - Scientists showed that ionization reduced bacterial
levels in burns and plastic surgery units by over 96% after a two week
period, which results in much better and more rapid healing of patients.
Journal of Applied Microbiology - The use of negative ions was even
found by scientists to reduce the presence of airborne viruses by about
40%. A study featured in the 1987 issue also showed the negative ions
are free from any adverse side effects.
Science - A 1976 study featured in this publication provided evidence
that negative ions can have a biologically lethal effect on airborne
microorganisms.
Journal of Hygiene - A 1979 study found that using negative ionization
in the air protected chickens from airborne infection of the deadly Newcastle
Disease Virus.
Journal of Food Protection - A 2001 study found that airborne negative
ionization was highly effective at destroying airborne and surface salmonella.
University of Medicine and Pharmacy (Romania) - A test on male rats
showed that just moderate levels of negative ions increased the resistance
of the rats, reducing or eliminating the effect of some chemicals. (Summary
of Study)
Effect of Negative Ions on Drivers - A study by
Toyota Central R & D Labs, Inc. found that negative ions can improve
fatigue and cognition of drivers.
