Andrew,

The short answer is that I simply do not know about this concept. I understand that electrostatic filters work under some circumstances, but I am a bit suspicious unless there is a lot of cleaning to do. I have some in my home, and I see nothing on them (but they are behind some of the regular filters, and so may not be seeing much). I tried a Google quiry, but my first one got something like 87,000 "hits." So in short, this question is out of my area of expertise.
