As information for the group, I wanted to provide my experience with
the Stetzer filtes and clarify a point that has been discussed a few
times now.

Like Vinny, I too have a EE background, am an extra class Amateur
licensee, and a physics background.
I have also had some recent psi/emotional openings and am still
trying to make sense of them.
Vinny seems much farther along on that path than I do. Someday I
hope to figure out more about that aspect.

I have been having ES problems for over a year now and most measures
haven't helped much.
I was convinced that ES was an issue after removing a cordless phone
from my bedroom and feeling much better.
My symptoms have included Tinnitus, foggyness, and just plain
"feeling gross", even some days I didn't think I'd make it through to
see the morning.

I bought the Stetzer filters and meter as kind of a "last resort"
given that other things (besides reducing exposure) had made limited
difference. Upon testing my house, I was surprised to see readings
ranging from 120 all the way up to 680 or so.
from what I can tell, this is quite high. Installing the filters has
definitely made a big difference, although it hasn't eliminated all
my symptoms.

I have noticed the number fluctuate greatly based on time of day and
can shift from one minute to the next.
With filters installed, however, I am mostly below 50 throughout the
house, below 30 at most outlets.
I still have some outlets in my home with readings as high as 200 at
times.
I haven't yet tracked down where this high frequency energy is all
coming from, but that's a goal for the future.

So, I have had fairly good luck with them. They definitely made a
positive difference for me.
I didn't notice any negatives at all, and none of the "pain in the
head" that Marc mentions.
Also, the units for the US that I was shipped seem well constructed,
sealed, and DO bear the UL listing.

Even though I've had good luck with them, I do want to add my
comments on the discussion between Charles and Shivani that has been
going back and forth for some time. Although I publicly disagreed
with Charles once on the list (regarding the electrical origin of the
earth's magnetic field), generally I do agree with and respect what
he says. And, since no-one has clarified this issue, I feel
compelled to...

On Nov 27, 2006, Shivani stated (in reference to Charles's comments
about creating a resonance condition)

This is not correct. Capacitors sum when paralleled, so in fact, 13
or 14 of them would just about equal 200uF. That is in fact about
the number a small home might use. At 180hz, the reactance of the
wiring in the home is mostly irrelevant, so for all practical
purposes every filter in the home would be wired in parallel.

If in response you say that it is not possible to EXACTLY reach 200uF
(13 would be 195uf, for instance), please note that electronic
components (including capacitors) are rated with fairly loose
tolerances, usually +- 5 to 10%, so hitting 200 exactly with 13 15uf
filters is just about as likely as with a single 200uF capacitor.

Whether or not this is a "problem" or causes a resonance condition
that would lead to problems I really don't know, although it seems
unlikely to me.

Having said that, I want to reiterate that my experience with Dave
Stetzer's products, in the US, has been very good, and construction,
shipping, and sales were all excellent. And they do have the UL seal
in the states.
