I’m not familiar with the intricacies of geopathic stress issues or Hartmann grid issues, but you can read about what some people have shared in this thread.
Another potential solution for your problems could be to use The Book of Cards. The physical book, which can be bought here, contains an Environmental Transformer which “…can create an active energy transformer, it will constantly draw in, filter and clean the energy in the environment you place it. Yes it is meant for the environment, not you. You place your item on the image, and say ‘create’ then it is ready to use in about 2 hours.”
Other potential solutions to your issues might be the The Schumann Resonance dog tag which has a strong grounding effect and even better (if you’ve got money to burn that is) Divine Balance which also contains (among other great fields) Om energy which “…also clears away negative and unwanted energies around its radius.” Though this wouldn’t really help with your environmental issues. The sapienshop just reopened and there’s a discount code ‘limited’ that gives 8% off. This seems to be a trial run that’ll go on until April 30th, in which they’ll close down the shop again and re-evaluate. This will not affect custom advanced fields like Divine Balance from the enlightenedstates website though.
There’s also The Sacred Flower which is basically The Plasma Flower on a dog tag which has “…the known bioactive plasma field with the flower of life on a torsion carrier which piggy backs on the earth’s resonance along with the node connector part.” The “Earth’s resonance” part is the Schumann resonance, so it potentially is very anti-emf as well.
Additionally, there’s the The Cyber-Magi. It seems to be based off the old Magnetic Field Capsules that kept you safe from negative/EMF forces.
And don’t forget about the Elektrosmog Album which can be downloaded on patreon that includes 3G, 4G, & 5G Protection, EMF Shielding, Negative Ion Generator and Radiation Protection & Removal.
