Over the past decade, the market has introduced many EMF protection devices which claim to block radiation. But, do they really work?
The truth is that some EMF protection products are really effective while some are just a waste of money. In this article, I aim to bring out which of the products listed below work and which don’t.
- Laptop radiation shields
- Cell phone radiation shields
- EMF protection paint
- Smart meter shields
- EMF protection pendants
- EMF protective clothing
- EMF protection crystals
- EMF neutralizers
Every electronic device we own emits some kind of radiation, whether it be magnetic, electric, or radio frequencies zone. Together these types of radiation are called electromagnetic (EMF) radiation.
Although there have been many studies conducted on the effects of EMF radiation, there are always several factors that need to be considered.
Factors such as age, proximity to device, and frequency of use can all impact the studies, and skeptics still think more information is needed before a conclusive link is drawn between EMF radiation and its health effects.
That said, there is no harm in protecting yourself from EMF radiation whenever possible. It’s possible to reduce your exposure by keeping your distance from electronic devices, or by limiting your use.
However, these aren’t always possible. One of the best ways to limit your exposure to unwanted radiation is to use an EMF protection device.
What is an EMF Protection Device?
EMF protection devices come in many different forms, but their main purpose is always the same: to limit the amount of EMF radiation that can pass through them. This usually happens through a use of certain materials that are effective in reducing radiation.
These materials include steel, aluminum, and other metals. You can also buy protective paint that blocks the majority of EMF radiation.
There is a range of other products on the market, such as pendants, jewelry, and stones that also claim to block EMF radiation.
While these products claim to do this through the materials’ natural radiation, there is little evidence to support whether these actually work.
This article lists the main types of EMF protection devices on the market, including shields, jewelry, and others, and looks at which ones work, and which don’t.
As mentioned, there is varying evidence on the impact of EMF radiation on our health, but all of the products listed in this article claim to reduce the amount we come into contact with.
The EMF Protection Products That Do Work
1. Laptop Shields
It’s perfectly natural to sit with one on your lap (hence the name) without ever thinking about the dangers of EMF radiation. Laptops also give off ambient EMF radiation when not in use, so we can be exposed to this just carrying them around.
Laptop shields come in varying styles, and these can range from carry cases to lap trays. They claim to drastically reduce the amount of EMF radiation that passes through them, and this is extremely useful if you spend a large amount of time using a laptop.
Many laptop shields will effectively double as both a carrying case and a lap tray, but it’s worth searching the market before buying one. It can also help to know how the shield claims to block radiation before buying it, as this will tell you how effective it will be.
Laptop protection shields are often made using materials such as aluminum or steel mesh, although they will often use heat protection materials too. This might all sound very bulky, but the technology has progressed so much that some are actually very thin and lightweight.
It’s also possible to get specific EMF shields that sit on your desk and protect you from radiation exposure from any other devices that you’re using.
So do they work? There is little conclusive scientific evidence on the efficacy of laptop shield devices. It’s possible to read user reviews online, but these won’t tell you about how well the product actually works.
However, one brand of laptop shields, DefenderShield (see it on Amazon), did get their devices independently tested by the FCC. The study found that the devices reduced exposure to EMF radiation by 99%.
This is an incredible reduction, and shows that the right combination of materials can make a massive difference to EMF radiation exposure.
2. Cell Phone Shields
Similarly to laptops, phones emit electric, magnetic, and radio frequencies, along with heat. Considering how frequently we use these devices, this can be a lot of radiation to be exposed to.
Cell phone EMF shields work in the same way as laptop shields, except they have to do it on a much smaller scale. This means having to use lightweight materials without reducing effectiveness.
Many use tiny gold-plated antennae or thin sheets of metal to reduce the amount of EMF radiation. Some are a lot easier to use that others, and look just like a normal cell phone case. However, some are very bulky, and so it can help to shop around for the right one.
Much the same as with laptop shields, there isn’t much evidence to confirm whether they work. Two brands, Defendershield and SafeSleeve (see their cases), claims their products have been independently tested by the FCC and can reduce radiation exposure by up to 98% in certain frequencies.
Although there isn’t much information about how well these EMF protection devices work, the studies that have been conducted show they reduce exposure by a significant amount.
The only way to 100% reduce levels of EMF exposure is to use a Faraday cage, but these will also stop you from being able to use your device. This is because they will block ALL electronic waves, including the ones that provide your cell phone with service. As a result, the best you can do is reduce exposure by a significant amount.
3. EMF Protective Paint
It can be necessary to use protective paint to reduce EMF exposure from devices such as televisions, Wi-Fi routers, desktop computers, and more.
Radiation protection shields are only usually designed for portable devices, and so other solutions are needed for bigger products.
EMF protective paint can be made from several different materials, but one of the most common in some form of silicate. This has excellent properties in terms of its EMF radiation protection, and is useful because it can be applied in the form of paint.
There are other materials available, but silicate (such as potassium silicate) does the best job.
The paint is often black, and is designed to act as a base layer under normal wall paint. Although some brands allow you to apply just one coat, they also state that the more coats you apply the more effective the protection will be.
However, these tubs of EMF protection paint can be very expensive, so know what area you have to cover before buying some.
That said, it’s not necessary for you to paint an entire room using the protective product. For example, if you’re looking to reduce EMF exposure specifically from a Wi-Fi router in a particular room (such as your bedroom), it’s possible to just paint the wall behind the router.
This will drastically reduce the amount of radiation seeping through the wall, and so will reduce your overall exposure. Doing it this way will also reduce the amount of paint you need to buy.
The most important step in the whole process is to ground the paint once it’s been applied. You can easily buy grounding cables and grounding plates online, and without these products the paint will be completely ineffective.
It’s also worth buying yourself an EMF meter to test how well the paint is working. This will also help you to tell whether you’ll need to apply any more coats to get the desired level of protection.
As with other EMF protection products, there aren’t any well-known studies about how effective this paint is. However, there are many reviews online on various e-commerce sites stating that this paint does work.
Considering it’s easy to test its efficacy using EMF meters, this can be done in your own home. One website, Shielding Paints, conducted tests into how effective different EMF protection paints are. They found that different paints offered varying levels of protection, so this should also help you to decide which one is right for you.
4. Smart Meter Shields
Smart meters are fast becoming a standard device in homes because they claim to give more effective readings than traditional meters. However, many people are against having them installed as they are viewed as an unnecessary alternative to a perfectly good device.
Smart meters increase your overall exposure to EMF radiation because they are Wi-Fi enabled, and use various different electronic components.
Your options for EMF protection depend on whether the smart meter is installed inside or outside your home. If it’s installed outside, then you can usually get away with much more clunky-looking devices.
However, if you’re serious about your EMF radiation exposure then you likely won’t mind building an EMF shield inside either.
Due to you not needing to use smart meters in the same way you would a laptop or cell phone, you have more options for how to reduce EMF radiation exposure.
There is a growing market for smart meter shields as more and more people have them installed in their home. A smart meter shield basically works as a miniature Faraday cage that you use to cover the device.
There are several different brands available so it shouldn’t be too hard to find one that fits your smart meter. These cages are often made of metal mesh, and some look a bit nicer than others. Read this article on my top recommended smart meter shield.
So do they work? The short answer is yes, and you don’t need scientific research specifically about these devices to know that. They use the same principles and materials as a Faraday cage, which is a known method of reducing EMF radiation.
The efficacy of the device will likely vary by brand, but some claim to reduce EMF radiation exposure by up to 98%, if not 100%. It’s also worth looking at customer reviews and testimonials, and testing any device you install with an EMF meter. This will be the only way to truly know whether the shield is giving you the protection you expect.
If you want to have the best chance of reducing EMF radiation exposure from your smart meter, it can be helpful to use a range of different EMF protection methods. For example, install a shield over the actual smart meter, and the paint the wall surrounding the device with EMF protective paint.
If you also paint the wall your smart meter is installed on then you will have the best chance of completely reducing your exposure.
The EMF Protection Products That Don’t Work
1. EMF Radiation Pendants/Jewelry
There are hundreds of different pendants on the market that claim to completely reduce your exposure to EMF radiation.
They claim to do this by either blocking or absorbing harmful radiation, and apparently provide a shield for your entire body. These pendants come in various styles, and can either be stones or metal.
The pendants work through a process called attenuation. This is essentially the gradual loss of force as energy passes through a material. For example, the muffling effect that happens when you hear sound through a wall. This is attenuation of sound energy, and the same logic can be applied to things like radiation and x-rays.
The efficacy of EMF radiation pendants, like all other protection products, depends on the materials used. Some are inevitably more effective than others, and it’s worth researching what materials the pendant is made from before making a purchase.
Do they work?
This is a difficult question to answer, but the information available leans towards no. The science and theory behind how the pendants work is correct, as attenuation is a real, observable phenomenon, and is actually how EMF radiation shields for electronic devices work. However, there is no evidence that supports pendants doing an effective job of blocking EMF radiation.
This has little to do with the materials used to make them, and more to do with the idea of wearing a small pendant to provide a protective shield.
In order to get complete protection from these materials you would need to be completely covered in them. A small pendant around your neck is going to do little to protect your entire body from EMF radiation.
As mentioned, the materials used to make these pendants sometimes do a good job of reducing EMF radiation, and this can be tested with an EMF meter. However, they do not do an effective job of protecting your entire body because they don’t emit a shield, and so would only protect the small part of your body they cover.
Rather than investing money in pendants, consider blocking EMF radiation at its source using protection shields for your electronic devices.
2. EMF Protective Clothing
There is a growing market for clothing that protects your body from radiation. The logic behind this is that rather than blocking radiation from each device, you simply protect your body instead. There is a range of clothing available, ranging from underwear, to t-shirts and jeans, to outerwear.
EMF protective clothing claims to work in the same way a Faraday cage works, in that it blocks EMF radiation using conductive metals. However, this logic is harder to apply to clothing because of the very way in which it’s made.
It would be inconvenient for your clothes to be made entirely of metal, and it’s possible that radiation would still find its way through the actual weave of the fabric.
Most protective clothing is made using silver, as this is actually a good material for absorbing radiation. The garments are made with silver thread that’s woven in with the normal cotton or polyester fibers. This obviously means that it won’t provide complete cover to any part of your body because it won’t create a protective shield.
There are plenty of these products available online, and their user reviews are the most information available on whether or not they work. That said, it’s very difficult to test the efficacy of clothing, as it can be hard to test accurately.
User reviews can obviously be quite biased, and many won’t have any hard evidence behind them to confirm any statements made.
The other big issue to consider is that EMF protective clothing won’t be very comfortable. If it’s made with metal, even if it’s only metal fibers, this will cause the clothing to be quite rigid, and means it might have an unusual shape.
Also, if the products do claim to be effective, it’s usually in varying amounts from 75% to 98%. However, there is no scientific or independent testing to confirm these claims, and without proof there’s no point wasting your money.
is a type of rock that was first named in the 19th century after being mined in Russia. It’s carbon-rich, often with a purity of up to 98%. It’s still only mined in Russia, but is available online from various sources, and is relatively inexpensive.
It has various industrial uses, but its primary use is as a pigment for types of black paint. It’s also quite effective at purifying water due to its molecular structure.
It’s this molecular structure that makes it of interest to people looking for EMF radiation shields. It contains a type of molecule called fullerenes, which are pure, hollow carbon molecules.
These hollow molecules are apparently ideal for absorbing radiation in various forms. You can buy shungite in different styles online, and these range from pendants, crystals, and large pyramids.
The efficacy of shungite in regards to EMF radiation is actually quite good. This video gives a little demonstration of what is apparently shungite blocking radiation from a microwave.
From the video, it appears that it doing quite a good job at this. However, it’s worth noticing that the shungite is being held by the fingers and it’s highly likely that the human body is absorbing the radiation and not the shungite.
Regardless of whether shungite actually absorbs radiation or not, it isn’t an effective method of EMF protection simply because it’s a rock.
Even if it works, shungite would need to exist as a physical barrier between you and the electronic device, and to get adequate protection you would need a large amount of it.
This would not only prove to be quite expensive, but it would also be very heavy and inconvenient. Plus, you could hardly wear a suit of rock everywhere you went.
4. EMF Protection Crystals
This largely covers both shungite and pendants in general, but there are a range of various different types of crystal available. They come in different forms, and can either just be the crystals on their own, or be made into jewelry. All of the different types of crystal claim to do the same thing: absorb EMF radiation through attenuation.
As mentioned above, this is a standard physical phenomenon that occurs in many different materials, and the actual act of whether these crystals can stop EMF radiation isn’t necessarily an issue. In large quantities they can be an effective way to block radiation, although their scientific merit as protection device has never been proven.
There are many different crystals that claim to offer EMF protection, but some of the most common available are: black tourmaline, amazonite, flint, quartz, fulgurite, and others.
Users of crystals believe that they both “cancel out” energy and emit their own positive energy. These are claims that have been made by people for hundreds of years, but as of yet there isn’t any worthwhile scientific information available to prove this is true.
Like with shungite, whether these crystals do block radiation or not isn’t really an issue. Many different materials have properties of attenuation, and to varying degrees of success.
However, the important thing to note is that these crystals don’t emit energy or force fields, and so they would only protect the small part of your body they were covering. Many users claim to leave a piece by their bed, but this would be equally ineffective.
The other important thing to consider is that if these crystals were so successful at blocking EMF radiation they would be more widely used.
If we’ve supposedly known about the radiation-absorbing properties of crystals then they would be the standard material used in EMF shielding devices, rather than materials such as metal.
When it comes to crystals, it’s your choice whether you use them or not, but as there is no scientific evidence to prove they work, it’s best to avoid them altogether.
5. EMF Neutralizers
Rather than blocking or absorbing EMF radiation, these devices claim to neutralize it. They do this by “retuning” the frequencies so they no longer cause harm to our bodies, and they do this through a combination of different crystal materials.
EMF neutralizers come in various different forms, but they generally look like a small disc that you stick on the electronic device you want to neutralize.
These devices claim to take a holistic approach to the issue of EMF radiation, and by neutralizing it instead of absorbing or blocking the radiation they claim to do a more effective job. This is because very few materials will absorb 100% of EMF radiation, and if they did it would have an effect on the way the device functions.
Neutralizers are apparently more effective because they don’t interfere with how the device works, and because they don’t have any complicated components, they effectively have an indefinite lifespan.
But do they work?
The short answer is absolutely not. There is no conclusive evidence to prove they work, and the very idea of converting or neutralizing EMF radiation through a combination of minerals is frankly ludicrous.
These devices are a scam, and a massive waste of money. So whatever you do, avoid them at all costs.
The world of EMF protection devices is complicated because there are so many different options available, and without research they can be incredibly confusing.
Unless something has been tested in a lab and has data to back up any claims there is little way of knowing whether it truly works.
When it comes to buying an EMF protection device, consider the following:
- Buy your own EMF meter. This will allow you to actually test any device you use.
- Look for data to back up claims.
- Stick with proven methods, such as device shields. These have been proven to work.
It’s also worth thoroughly researching whatever section of the market you’re buying from, and be careful how much you trust a protection device based on user reviews.
