The reason for this is that the filters work best when they are placed closest to the various sources of dirty electricity (high frequencies). Examples of typical sources are: computers, TVs, dimmer switches, compact fluorescent or regular tube fluorescent lights, LED lights, high powered motors like vacuums and blenders, variable frequency motors like modern furnaces/AC units, dehumidifiers, sometimes refrigerators, and much more. You can identify a device or appliance as a source by using the
Stetzerizer Microsurge Meter and plugging it into the same outlet (remove any nearby filters while measuring) and then turning the device in question on/off or plugging it in and unplugging it.
But the filters work much better when installed properly - throughout the home in each room and when there is a source of dirty electricity then it's best to put 1 or 2 filters into the same outlet or power strip as that device that is producing dirty electricity.
We have not found any other type of filter that we recommend using yet. The Stetzerizer filters work far better and are usually much less expensive than whole house filters.

Q) I install a filter, but the reading doesn't go down to 30 or below. What can I do?
A) The first filter you install will bring the reading down the most.
So if you are starting at 500 G/S units on the meter for example, one
filter may bring it down to 50. 50 is still higher than (we recommend
30 or below is good, and the back of the meter says 25 or below is
ideal) we'd like to see. Try installing another filter at the same
location. You may need to use an outlet adapter that plugs into one
plug and gives you 3 empty plugs, just while testing to allow you to
have 2 filters plus the meter plugged in at the same time.
The easy rule to remember is the 20% rule. Anytime we plug in a filter
we want to see at least a 20% reduction. So if you are at 50 with 1
filter, try installing another. If it goes down to 40 or lower, then
that is a good 20% or more reduction, so leave the filter. If it goes
down only to 48 for example, the filter is probably better used
somewhere else. Sometimes you will run into a wall where you can't seem
to get it any lower. You can try installing a few extra filters to see
if you can breakthrough, and sometimes you can, but not always. You
can also consider
installing filters by your main circuit breaker.

Q) My meter displays a 1 or a 0 or doesn't display anything when I plug it in.
A) Your meter has "maxed-out" which means the reading on the line you
are plugged into is over 2000 (two thousand) and the meter is unable to
display it. When you install a filter on that line, it should
immediately come into a readable area, most likely under 100 G/S units.

Q) My filters make a buzzing or humming sound. Are they defective?
A) This is rare, but is nothing to worry about. Your filters are not
defective. Some people may notice a slight hum or buzz of the filters.
This is caused by certain frequencies on the line that are most likely
coming from your utility company (the electrical grid). The particular
frequencies are just right to make the filter(s) resonate with them.
This can sometimes be alleviated by adding more filters. If the hum is
very loud, you should definitely add more filters and ensure that all
your circuits with plugs have at least 1 or 2 filters on them. There
are sometimes other things that can be done as well. Dimmer switches
and some other types of lighting can cause a hum. Contact us if you
need help with this issue.

Q) When I install a filter in my kitchen, the reading in the outlet
goes down, but the reading in another outlet goes up. Why is this??
A) This can be caused by improper wiring in your home. Sometimes
multiple circuits share the same neutral return, causing an imbalanced
load. Under these conditions you could have the reading in an outlet go
up. Some other things can cause this too. Try installing more filters
at the problem site and this usually solves things. Look for the best
combination of filters to reduce the readings everywhere as low as
possible.
