2 Stetzer Filters

A technology designed to improve power quality in home and office environments. Easy to install. Simple plug-in design. Use as many as needed for your situation. (Meters are also available.) 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 from televisions, computers, variable frequency drives, energy-efficient lighting, etc.. Designed by Graham Stetzer. --- We recommend a minimum of 4 filters even for a small place. In order to exactly measure your situation you need a Stetzerizer Meter.
