Hi Amanda, welcome to the forum. There is a review of the Trifield meter on the main site here (https://www.electricsense.com/1336/is-the-trifield-100xe-the-best-emf-meter/) which you may have seen. According to the specification it covers some but not all of the ‘dirty electricity’ (DE) frequency range. The trifield measures in the room so it is quite different from the meters which are usually used for DE. It also has the advantage of measuring other frequencies as well, although it has some limitations (see the review). In particular it seems that the DE is measured along with the actual power frequency fields – which might make it difficult to determine which is causing the problem, as the remedial action is quite different. Most practitioners recommend a meter which measures DE specifically within the actual wiring, either a Stetzer meter (https://www.stetzerelectric.com/store/stetzerizer-microsurge-meter/) or one of these (http://www.emfields-solutions……etekta.asp, also obtainable from other sources and in the US). As well as the info on the main site here there is an excellent article on measurement and filtering here (http://www.powerwatch.org.uk/l…..sourceID=1), and another here (http://createhealthyhomes.com/…..ricity.php) which covers the different types of filters which are available. My personal experience is that a few Stetzer-type filters work quite well most of the time, but not always, and that placing them is as much an art as a science, needing some experimentation to get the optimum result. I like the look of the PxDNA filters (also mentioned on the main site here), but I have not had the opportunity to experiment with them.
This is quite a complex area, difficult to cover adequately in a forum posting. If you have any more questions, just post a reply and I’ll do my best to help. Depending on your level of experience and familiarity with all this it might be worth getting a Building Biologist to have a look at your situation to make sure you are addressing the most important problems, as the measures discussed here do not cover all issues – including radio frequency (wireless) emissions and power frequency magnetic fields.
