Dirty Electricity Meters

Dirty electricity meters, the fourth type, measure electromagnetic interference present on electrical wiring. Dirty electricity refers to the irregular and potentially harmful electrical frequencies that can be generated by certain modern electrical devices and dimmer switches. These meters detect spikes and surges in electrical power lines that are not part of the regular 50/60 Hz electrical frequency. Measuring and mitigating dirty electricity is crucial in environments where there is a high usage of electronic devices, as it can contribute to electromagnetic pollution, potentially impacting health and the performance of sensitive equipment.

Once you’ve taken measurements with these meters, you can then take action to remove or replace the sources of DE or reduce DE levels through plug-in filters or full home filters​​.

Since these types of meters need to plug into outlets, make sure to get a dirty electricity meter that is designed to work with the power grid where you live.
