message: It seems like this article and the "scrubber" article should be more interconnected. I don't claim to be an engineer, but seems like the majority of industrial processes for an electrostatic precipitator will fall into the category of also being a scrubber.

message: "Once the particles are in contact with the positive plate, they then give up their electrons and become positively charged like the plate, and thus start acting as part of the collector."
: Wouldn't the fact that they become positively charged mean they are repelled from the positively charged plates?  This is what happens to pith balls/hairs/paper shreds on a charged metal object, for instance.  They are attracted at first, contact the metal object and become charged the same way, and then are suddenly repelled. — Omegatron 19:29, 25 October 2006 (UTC)

message: At the end of the section for "Modern industrial electrostatic precipitators" i would like to suggest that the following text is added. Any comments/contributions would be appreciated
"These ‘rapping systems’ are usually mechanically operated by means of rows of staggered rotating ‘hammers’ which strike the plates in turn. This constant mechanical hammering action can sometimes cause internal damage which can result in sections of the ESP becoming inoperative and therefore reducing the overall efficiency of the ESP. A decision then has to be made as to whether to commence an unscheduled shutdown to carry out repairs or to continue operating the ESP in its damaged state until the next planned shutdown is due. Largely because of this, sonic soot blowers are installed to either partially or fully replace the mechanical rapping systems. These sonic soot blowers use non-destructive high energy-low frequency sound waves which prevent the particulate from building up on the collecting plates."

message: On ther internet I find alot of what are called "electrostatic air filters". Yet on comparison there workings seem somewhat different than the wikipedia article. The air filters are loaded through friction of the air en dust is attracted. (No two parts with a voltage difference, no collector plates, no ozone, aso...) 
For example: http://www.dustfree.com/filters/faq.htm http://acfilter.com/categories/faq/faq.htm http://www.lifetimeelectrostaticfilter.com/
Even if these are bogus: aren't they worth a mention?  — Preceding unsigned comment added by BartYgor (talk • contribs) 15:16, 17 April 2011 (UTC)

This is is a HEPA-based air purifier with a proprietary "PlasmaCluster" ion generator on the exhaust. This device generates oxygen and hydrogen ions that, supposedly, will chemically attack pollutants.
