A Simple Solution: reduce Dirty Electricity with plug-in EMI Filters
Two companies, Stetzer Electric and Greenwave™ specialize in the measurement and reduction of dirty electricity in a variety of settings. Stetzer Electric sells a plug-in EMI filter, which the company claims is based upon 100 year-old science and power engineering principles. Early literature from the company claimed the filters reduce stray electrical frequencies in the 4-150 Kilohertz range. The single capacitor solution is housed in a basic, tan rectangular box at price of between $30 and $35 per filter.
Greenwave offers innovative EMI filters in an attractive, industrial designed footprint for between $21 and $25. Greenwave filters mitigate stray frequencies between 10 kilohertz and 500 megahertz (at 30 DB) and is the first to incorporate nickel-plated components, grounded circuitry and a convenient plug-through feature. Greenwave filters incorporate a system of multiple capacitors, which include attenuating both the ‘hot’ and ‘ground’ circuits. Greenwave filters were designed in partnership with a notable defense contractor, which specializes in EMI mitigation. The filters use state-of-the-art electromagnetic interference (EMI) filtering technology to reduce levels of potentially harmful electrical energy.
Easy to install: it usually requires between 12 and 24 filters per home. You may plug the filters into outlets or power strips.
