Studies proving the effectiveness
of Negative Ions to purify air, etc.

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 ARS Study)

"We have a cat that insists on sleeping at the foot of the bed. After two weeks of usage, it's hard to believe how I could have lived for so many years without your great product. No more stuffiness, greatly reduced post-nasal drip and NO snoring (so says my wife)." - B. E. Kendall, Washington
 

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.

Effect of Negative Ions on Drivers

A study by Toyota Central Research and Development Laboratories, Inc. found that negative ions can improve fatigue and cognition of drivers. (Copy of Study - PDF File)

" On a whim ... plugged it in next to the computer where ... fumes tend to collect. I am soooo happy to say that I can now work for hours at a stretch without having to suffer a headache! The fumes have completely disappeared from the area!"
A. Berry, California
 

"After one week saw a dramatic difference in her. The cough she would wake up with on a daily basis was virtually gone. Her daily sniffles and sneezes were all gone. She has many allergies especially dust mites and mold."
A. Kesten, New York
