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."

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.

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.

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.

|
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.

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

Surround Air Negative Ion Generator product testimonials
" 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!"

"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."
