Dirty electricity line filters increase AC magnetic field. DNA devices do not. One line filter needs to be tested for AC magnetic field and power line hacking.

"Please note that the filters them selves emit some low level of ELF EMR, so you need to keep at least 50cm safety distance from them. For EHS people we recommend to first try out several filters before ordering a big number of filters."

"After doing some steps to minimize the levels of Dirty Electricity in your house, it is possible (and recommended) to filter out the remaining Dirty Electricity....Since the filters are not cheap it is recommended to install them only after the levels of Dirty Electricity is minimized by unplugging sources of Dirty Electric from the electric supply and only then to measure Dirty Electricity and install filters."

Those who are being power line hacked, please test and report. I will do likewise.
