A new application of existing science and technology designed to improve power quality in home and office environments
 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 slightly inductive.
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.
The reader is encouraged to review the STETZERiZER Microsurge Meter Product Description, the STETZERiZER Filter Installation Instructions, and the STETZERiZER Filter Frequently Asked Questions.
Filter Installation Instructions
STETZERiZER Filters are very easy to install on your own. Follow these instructions to maximize filter effectiveness.
Note: Many homes may not have enough open outlets to install the number of filters needed to clean up the home. If this is the case, purchase several power strips, plug your electronic devices into them, and install filters in the power strips as per the instructions below.
One filter should be installed in power strips where each of the following electronic devices is located:
• Hair Dryer
• Mixer
• Blender
Two filters should be installed in power strips where each of the following electronic devices is located:
• Personal Computer
• Laptop Computer
• Inkjet Printer
• Fax Machine
• Personal/Home Office Copier
• Entertainment Center (TV, VCR, DVD, Stereo, etc.)
Three filters should be installed in power strips where each of the following electronic devices is located:
• Laser Printer
• Large Office Copier
One filter should be installed in an outlet on each wall of the rooms you spend the most time in, especially bedrooms. Other rooms where this should be done may include your living room, kitchen, den, etc.
Two phases of current are used to supply utility power to your home: A phase and B phase. One filter should be installed in an outlet on each phase of current as close as possible to the main electrical panel in your home. Most homes will have one electrical outlet dropped down directly from the main panel; installing a filer in this outlet will take care of one current phase. For maximum effectiveness, call your local electrician and have him or her drop another outlet down from the panel on the other phase, then install a filter in that outlet as well.
When these directions are followed, a sufficient number of STETZERiZER Filters should be installed to effectively clean up the average home.

Designed to measure home and office Power Quality
 Electrosensitive people have reported sensitivities with readings as low as 27 on the Microsurge meter. However, medium or even low Microsurge meter readings should not be interpreted as a guarantee that there is no harmful health impact; only a medical expert can determine that. Caution is required. Some harmful health effects of high frequency energy on humans appear to be cumulative, and possibly non-reversible. Science is inconclusive in this area, although the body of empirical evidence available for guidance continues to expand and stabilize.
Microsurge Meter Design Criteria
Microsurge meters were specifically deigned as a companion to the STETZERiZER filters. The meters measure the level of harmful electromagnetic "energy" present, and their primary use is to guide effective filter installation. Microsurge meters are low cost, robust, and easy to use by non-technical people. The meters were designed to measure harmonics and other high frequency "energy" present, which are the frequencies most detrimental to human health. The meters effectively ignore the effects of 60 Hz power and other lower, less harmful frequencies. Specifically, the meter measures the average magnitude of the changing voltage as a function of time (dV/dt), which naturally emphasizes transients and other high frequency phenomena that change rapidly with time. The measurements of dV/dt read by the meter are defined as G-S (Graham-Stetzer) units (since no standard term is available). The G-S units are a measure of "harmful energy" which is a function of frequency, or more generally, rate of change of voltage or dV/dt.
Using the Microsurge Meter for a Typical Home Installation
Microsurge meters measure the levels of safe, borderline, or dangerous levels of "energy" present. These levels are conveniently shown on the back of the meter for reference. These levels have been developed through research (much of it in Russia and neighboring countries) and confirmed by experience in North America. The levels have been adopted by the Sanitory Stations (Health Departments) of the Republic of Kazakhstan.
Starting from points that typically have the highest readings such as the power input panel, computers, and televisions, the meter is used to measure the initial levels of G-S energy and reduction as filters are added. Once the G-S levels are acceptable at one location, the process should be repeated at the next location. After the installation of the filters is complete, a final confirmation of the G-S levels should be performed throughout the house.

What are STETZERiZER Filters for?
STETZERiZER Filters remove or reduce high-frequency pollutants from the electrical wiring in your home or business.
How can I tell if I need STETZERiZER Filters?
If you and your neighbors have electronic equipment connected to electric outlets you need STETZERiZER Filters. The STETZERiZER Microsurge meter can be used as an aid in determining exactly how many filters you may need.
How many STETZERiZER Filters do I need?
It usually takes 20 filters to effectively Òclean upÓ the average home. Homes with more electronic equipment (i.e. computers, printers, fax machines, televisions) may require more filters. View our filter installation instructions for more information.
What is the lifespan of STETZERiZER Filters?
STETZERiZER Filters are not like oil filters that fill up with use. They are an electronic component, and should last a lifetime.
Do I need an electrician to install STETZERiZER Filters?
No. STETZERiZER Filters are designed so that anyone can properly install them. Simply plug the filters into an electrical outlet or power strip.
How do I install STETZERiZER Filters in my home?
View our filter installation instructions document for more information.
I plugged in a STETZERiZER Filter and there was a spark. Is this normal?
Yes, it is normal for the filters to spark when being plugged in. This should not hurt you, your electronic equipment, or the filters.
I plugged in a STETZERiZER Filter and it started humming. Should it do this?
No. When a STETZERiZER Filter is humming, it is overloaded. To resolved this problem, simply plug in more filters. Remember, it takes an average of 20 filters to clean up a home. One or two filters cannot do the work of twenty.
How can I tell if a STETZERiZER Filter is working?
The only way to tell if a STETZERiZER Filter is working is with the use of an oscilloscope or specially designed meter. However, many people claim they can tell the filters are working because they start to feel better.

In today's world of wireless technology, our microwave exposure is increasing at an alarming rate. Because an individual is now likely to be subject to frequencies being broadcast from multiple sources (some of which may be purposely hidden), and because these frequecies often "bounce" off of surfaces, the only way to be aware of your safety level is to have a device that registers your actual exposure.
The Electrosmog Detector, introduced in August, 2005, was made to fit this need. Its creators in the UK sent me one to try, and I was so impressed with it that I have become a US distributor. This easy-to-use device is easily carried in a pocket or purse, and costs only $90.
The Detector enables you to literally hear the electrosmog that exists all around you. The level and quality of the noise the Electrosmog Detector emits is directly related to the changes in levels of man-made microwave radiation.
Unlike anything else on the market at present, it detects and sums the totality of the incoming microwave radiation amplitude modulation above about 30 millivolts per metre strength, allowing you to hear the result. Both accurate and credible, the Electrosmog Detector is the first true consumer product in this category.
Studies indicate that 0.01 V/m (volts per meter) is the starting point of health effects. That is why the Detector starts to activate at exactly that point. If you can detect noise on it there is reason to take notice. If you get a lot of noise, especially where you spend a lot of time and particularly in bedrooms, then you need to do something about it. The device makes it possible to identify "hotspots" and to create "quiet zones." For most people, minor lifestyle adjustments can lead to dramatic reductions in exposure.
You can see the Electrosmog Dectecter, read about it and even hear clips of the sounds it emits when exposed to various wireless broadcasts. In my experience with it so far, I have heard sounds even more impressive than those recorded on the Web site. It is extremely interesting to actually be able to hear the different frequencies, the pulsing, etcetera.
As cordless phones create such an extreme exposure, I would like to comment on them in particular. Many wireless phones broadcast continuously, even when not in use. The frequency used is above that used by cell phones, in the GHz (giga Hertz) range. ( When you click the "on" button on the handset, a totally different even higher-pitched whine chimes in as well.)
People using cordless phones or child monitors should understand that the the exposure from these can be similar to that experienced from living near a microwave tower. (Please note that old cordless phones are analog. The frequency they use is just below the range of that heard by the Detector. )
Also note that most of the microwave ovens in homes I have checked broadcast microwaves though the entire kitchen and into adjacent rooms when the oven is used.
