I wonder about Shivani's statement:

"No other product does what the Stetzer filters do."

Meanwhile, I've seen a variety of products that are sold
as "power conditioners" or "EMI/RF filters". Some of
them are very expensive, and are sold to high-end
audio enthusiasts who use them to improve the audio
quality of their equipment, while others are found
in power strips found in the local hardware store.
Is there something truly unique about the Stetzerizer
filters, or are they simply yet another capacitor-based
shunt filter? (I seem to recall that the Stetzerizer
website once said that the technology they were using
had been around for 100 years, and they also gave
instructions on how to build your own, so I think
the technology is not so unique).
