The STETZERiZER® Filter is based upon 100 year-old
science and power engineering principles. Newly introduced is the
design, which is focused on the needs of the customers in homes,
offices, schools, etc. Filters have been extensively applied for decades
by industrial users and the electric utility industry itself. The
STETZERiZER® Filter is designed to filter harmonics and other high
frequency current (trash) from the electrical environment, thereby
reducing the potential for leakage into the human environment and
creating additional trash in non-liner loads (televisions, computers,
variable frequency drives, energy-efficient lighting, etc.).
The high frequency current (trash) on the neutral wire in the
electrical system is positioned to return directly to the power system
via the feeder neutral to the substation, and possibly beyond. However,
as is often the case, the utility feeder neutral is not adequately sized
(as required by the Public Service Commission of Wisconsin). If this is
the case, much of the return current will flow through the ground
rather than the feeder neutral. Under these conditions, the STETZERiZER®
Filters still provide benefits; this should be seen as local mitigation
rather than part of a complete solution that requires an adequately
sized neutral return.
At 60 Hz the filters act as capacitors and normally marginally
improve the power factor of the customer load, which are normally
Typical Home Installation
Filters are designed to be installed throughout the home in a pattern
that corresponds to the distributed nature of the need. For example,
installing two filters close to a desktop computer or a television is
normally appropriate and effective. Installing filters, normally from
two to six, close to the input power panel is recommended to address
high frequency currents entering on the power lines. The total number of
filters required depends on the size of the home, the amount of
electrical equipment, and the quality of the power from the grid. Twenty
filters are normally adequate for a “typical” house.
Installing an inadequate number of filters tends to result in
overloaded filters, leading to an ineffective solution. The preferred
installation method is to be guided by the STETZERiZER® Microsurge Meter,
which measures the amount of high frequency energy present. Readings of
30 or lower indicate an acceptable environment, while readings of 50 or
higher indicate a need for additional filters. Readings between 30 and
50 are marginally acceptable, but should be reduced if anyone in the
area is electrically sensitive.
As referenced in the STETZERiZER® Filter FAQs,
a typical home requires about 20 filters before its environment is
effectively “cleaned up”. While your home may require a different number
than this, we recommend purchasing 20 filters to start. We understand
that this may be a substantial investment, but after years of
experience, our results speak for themselves. We recommend purchasing a STETZERiZER® Microsurge Meter if you want to measure the exact amount of filters needed to clean your specific environment.
