EMF filters work. You do need the test meter
I followed the simple instructions for testing each outlet and adding filters where needed. The test meter is essential. Also if you know how your house is wired (which receptacles are on which circuits) that also helps. I found 4 filters a great starting place for an 1800 SF home, but plan on adding a few more. Glad to get this done ahead of the 5G that will increase our exposure to EMFs.
