on computers performance/life?

esoteric...

My searches turned up absolutely no cautions about the possible
negative impact of ionizers on computer health or lifespan
(see the searches listed below).

What did show up is that computers, along with monitors, put out
a great deal of positive ions (which have a negative impact on 
human health and lifespan) and that ionizers are a good thing to
have near the computer, for the sake of the user(s).

See:
Negative-Ions and Computers
Article #505

by T. Neil Davis

"This article is provided as a public service by the Geophysical
 Institute, University of Alaska Fairbanks, in cooperation with
 the UAF research community. T. Neil Davis is a seismologist with
 the Institute."

"The electric field caused by the positive static charge that
 appears on a CRT in normal operation sweeps the nearby air of
 negative charges, thereby depleting the negative-ion concentration
 in the immediate vicinity. Apparently when the ion concentration
 is lowered by this or any other means--air conditioning does it
 too--workers complain of headaches, lethargy, dizziness and nausea."

and

"After the experimenters turned on the ion generators, they found
 that the tested persons had fewer headaches and other complaints
 than before. Only five percent then said they had headaches,
 whereas 20 percent of the workers complained of headaches before
 the ion generators were turned on. The number reporting dizziness
 and nausea dropped by more than half, down to less than one percent."

Here's an ionizer specially designed for use in computer areas,
sold online by MGT.com:

"Our ES-2000 is specially design for computer user and in area
 where computers are present. A lot of research have been done
 by scientists that computer monitors generates a dangerously
 high level of positive ion radiation in the faces of computer
 users. Positve ions radiation can cause computer users to
 experience depression, anxiety and fatique. The hazards of
 working with computers are very serious. Using our ES-2000
 helps to reduce all this symptoms."

"OUR ES-2000 generates NEGATIVE IONS consistently to neutralize
 the positive ion generates by the cathode ray tubes(CRTs) in
 the computer monitor."

Another site which sells ionizers notes in their FAQs:

"If you have computers, placing an ionizer two or three feet
 from a computer monitor (to your right or left) will help
 neutralize the positive ions that emanate from the monitor."
http://www.negativeiongenerators.com/faq.html

They sell a separate "Dust-Grabber" unit in conjunction with
their ionizer, or you can purchase their all-in-one model.

Since ionizers also attract and trap dust from the air, one placed
in the vicinity of your computer should also reduce the amount of
dust which enters your computer and is deposited on the fan blades
and internal components. Such dust is known to shorten PC life by
acting as a blanket on components, slowing the fan speed and 
increasing the operating temperature, which is one of the main
factors in the lifespan of a computer.
