I have referenced Furman equipment several times. This is a link to a discussion a member of our local group wrote. This guy designs and builds SET tube units and does the designs in his head! I kind of understand what he is talking about sometimes, but he is WAY smarter than I am.

Anyway, it is not so much dirty power that some conditioners work to clean, it is the consistency of the power. The technical term is Power Factor. Furman unit address this.

Here is the link:

The thread is long but the sections by 'SET' are the one's to read.
