STETZERiZER® Filter
The STETZERiZER® Filter is based on 100 years of science and power principles. This design focuses on the needs of our customers in homes, offices and schools. The STETZERiZER® filters harmonics and other high frequency current (trash) from the electrical environment, 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.).
Overview
In a typical alternating current (AC) power line, undesirable pollution often occurs. The effects of transients (electrical surges) and harmonics generated, oscillating at frequencies higher than 60 cycles per second on the power line are prevalent today. This pollution comes from non-linear loads and for example, can be caused by a switched power supply, motors or appliances that send high frequency signals into the line. Nonlinear loads are produced by electronic devices such as computers, printers, switching on and off, capacitors switching off lines to balance loads, trees brushing hydro lines, and faults on circuits. Harmonics are often called electrical noise and produce the humming, buzzing sound around poles and lines, and radio noise heard near electrical power lines. These high frequency signals from harmonics and transients are radiated into your home or office environment.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.
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.
In order to give you best results, we use the STETZERiZER® Microsurge Meter when we help you install these filters. The filters are available from us.
