Our Story
For more than two decades, Dave Stetzer has focused on troubleshooting power quality problems, specifically the problem of dirty electricity (electrical pollution, “stray voltage”), in the United States and in numerous countries throughout the world. His work in this area led to the development of the STETZERiZER® Filter, the world’s first power line EM (electromagnetic) filter.
Along with the late Professor Martin Graham, Dave also developed the STETZERiZER® Microsurge Meter. The only meter of its kind, the STETZERiZER® Microsurge Meter is the gold standard in dirty electricity measurement. Both STETZERiZER® Filters and the STETZERiZER® Microsurge Meter were designed from the ground up to be the easiest, most effective tools the average person can use to eliminate dirty electricity from their home, workplace, or other electrified environment.
STETZERiZER® Filter
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.
STETZERiZER® Microsurge Meter
The STETZERiZER® Microsurge Meter by Graham-Stetzer is designed to separate the power line frequency to detect and respond to low level high frequency voltages caused by transients and harmonics on power lines. The level of these voltages is measured in GS (Graham-Stetzer) units and will vary with electrical equipment and loads.
