Reducing EMFs and “shielding” against them can often be used interchangeably, but they’re actually two distinct things which I’ll explain below.

Reducing EMFs

Before reducing EMFs in a home, I break them out into four main categories for simplicity’s sake, and not only does it make it easy for me, but it also makes it easy for my clients as well:

  1. Personal stuff and gadgets: these are the things one might have or carry around with them. Things like cell phones, headsets, tablets, laptops, or wearable tech.
  2. Things in the home: such as TVs, speakers, personal assistant devices, clocks, appliances, etc… basically just about anything that’s in the home that you wouldn’t be carrying around with you
  3. Things that can affect the entire home’s EMF fields: such as wiring, net current, security systems, solar panels, etc…
  4. Things outside of the home that can affect the entire home’s EMF fields: like cell towers, power lines, service drops,

Reducing EMFs in these categories can vary widely for each individual, let alone what they have in their home and things that are affecting their home.

Most people think of reducing EMFs in terms of their personal gadgets, but it’s important to include the other categories because they can significantly impact your health as well.

Reducing your exposure to EMFs in the second, third, and fourth categories are more difficult without using instruments, but it can be done if you know what to look for and how to prioritize them.

Shielding EMFs

Here’s where the fun begins!

Once measurements are taken for the different kinds of EMF fields for the categories listed above, then reducing them and shielding can start.

The biggest mistakes I typically see are people who don’t know about the different types of fields, sources and nuances within the frequencies, and do shielding, only to make a situation worse.

To keep things simple, I break shielding into categories as well:


Non-permanent shielding is exactly what it sounds like. You can put it up and install it and remove it when you want.

It could be something like fabric shielding in a certain area, such as a bed canopy or curtains.

It could be wire mesh over a window screen or window.

There are also window films which require a bit of work to remove, but also available to shield a window where RF is coming through.

Or perhaps an enclosure that limits the amount of RF emitting such as a smart meter cover, or a cage for a utility meter


Permanent shielding is usually an EMF paint that can be installed internally or externally on the home which requires grounding. Once this paint is applied, it cannot be removed. Even if you try to scrape it off, it won’t remove it!

The best thing about the paint is that you can paint over it, and one would never know an EMF paint has been installed until they step inside the room or space that’s been painted.

An important thing to keep in mind is that all valid shielding materials will be guaranteed to shield fields up to certain thresholds (which is why it’s critical to measure all of the fields with professional instruments before installing any shielding whether it’s non-permanent or permanent). For example, if you have fields that are say, 50, and the material you’re using is only guaranteed up to a 30, then the field will still go through the material. Depending on how that field behaves inside a shielded space, it may also increase.

Shielding is typically a combination of non-permanent and permanent solutions, depending on where the sources are and the strength of the fields. Almost all of the clients I’ve worked with have been surprised at how easy shielding can be once their home has been measured and there are clear choices and options for them.
