What Is Dirty Electricity?

Dirty electricity is electrical noise at frequencies other than the intended 120V 60Hz power signal. In the explanation published on trifield.com's knowledge base (January 28, 2025), it is described as originating from various sources, existing in multiple forms, and going by several names — including line noise — all referring to the same phenomenon: electrical noise in frequencies other than the intended 120V 60Hz.

Why the name varies

Because the phenomenon shows up in different contexts, it has picked up different labels. "Dirty electricity" and "line noise" are two common terms for the same thing, according to the Trifield knowledge base article. If you see either term, the underlying idea is the same: unwanted high-frequency content riding on standard power.

What the source does and does not say

The available material from trifield.com establishes the definition and the naming variation. It does not, in the excerpt provided, list specific sources, quantify health effects, or give measurement thresholds. Those details would need to come from the full article or other sources.

Where this fits in Trifield's material

Trifield (trifield.com) is the site for the TriField® EMF Meter Model TF2, made by AlphaLab, Inc. The meter is described as detecting three fields — magnetic, electric, and radio — with standard and weighted modes, a backlit display, and a one-year warranty, priced at $186.00 on the page. The knowledge base that includes the dirty electricity article also covers EMF shielding techniques and electromagnetism basics.

If your goal is to understand the term itself, the definition above is the core takeaway. If your goal is to identify or measure dirty electricity in a specific location, the TF2's three-field detection is the relevant capability described on the site — though the excerpt does not state that the TF2 measures dirty electricity directly, so treat that as a separate question to verify.
