Best Anti Radiation EMF Block Phone Cases:Do They Work?

Anti-radiation or radiation blocking or phone shield cases. Do they Work? SafeSleeve, DefenderShield, Vest, Alara, Pong, Reach and ShieldMe  and other EMF protection phone cases claim to block the radiation from your cellphone or smartphone. Anti-radiation cellphone case brands make enticing claims like this: ". . .eliminate up to 99% of the harmful radiation coming from the phone!"

But Do They Work?

. . . because blocking radiation (the electromagnetic fields that come from wireless cell signals, WiFi and Bluetooth) is an excellent idea. A really excellent idea in fact, because that radiation, sometimes called EMF or EMR or wireless energy, has been proven in studies over the last 30 years to be harmful to our health.

Cancer and Other Nasty Things Are Why We Want Anti-radiation Cases To Work

Dr. Leigh-Erin Connealy, Director of The Center for New Medicine, just published her latest book The Cancer Revolution, A Groundbreaking Program to Reverse and Prevent Cancer. Dr. Connealy recommends avoiding cellphone radiation exposure as one component of cancer prevention.

From Dr. George Carlo, to Dr. Joel Moskowitz, to the Environmental Working Group, to the Environmental Health Trust, world class experts are all sounding the same caution. Check out this from EHS on cellphones and breast cancer.

You CAN Block 100% of Cellphone Radiation, but You Can't Use Your Phone At the Same Time.

To block enough radiation from your cellphone to be safe, you would have to use an anti radiation faraday case. They really do block 100% of signal. But, while there's no radiation in or out of the Faraday case or bag, there's also no cell signal. Meaning you can't use your phone.

So, We asked Around. Do Experts Think Anti-radiation or Blocking Cases Actually Work?

We couldn't find one legit EMF expert online or anywhere else that would recommend a radiation blocking case or anti-radiation case. Not the Environmental Health Trust or Magda Havas, or Joel Moskowitz, in fact his site, safeEMR cautions against scams and claims for radiation protection.  So if a so-called "EMF expert" is recommending any kind of anti-radiation case, they probably aren't that much of an expert. 

Look For Science Backed Answers

I really want to caution you to be careful of any "expert" or EMF blogger recommending anti-radiation filtering cases, stickers that attach to the phone or necklaces to "ward off" EMF.  I get it, when I first realized 25 years ago that I was sensitive to electromagnetic energy and then later, when I understood that without a doubt, man made electromagnetic radiation has a biological effect on my body, I wanted an easy fix.  I tried the shielding materials and cases and I just did not feel any better.  Then I bought meters to see if the energy changed and I actually noticed what the California Department of Health now says and it's what the FTC and FCC post warnings about:  "Some shielding materials can make exposures worse". So please, be careful and read on for what you can do to avoid electromagnetic radiation exposure.

We Bought 6 Anti-radiation Cases to Try Ourselves

These are the highest profile cases available and here's what each company says about how their cases block radiation.  The photo below shows a phone with no case measuring at the PEAK LEVEL of radiation. 

iPhone with no case radiation


SafeSleeve Anti Radiation Case: Safe Sleeve website says they integrate FCC accredited independent lab tested "shielding technology" in their products. There are many links to "SafeSleeve, Is it a Scam?" and "Does SafeSleeve work?" online, but if you follow those links you'll find they go to the actual SafeSleeve site where the question of SafeSleeve protection is addressed.  You'll see in this demonstration that the radiation level was higher with the SafeSleeve Case on.

SafeSleeve Black Case

Vest Anti Radiation Phone Case: The Vest Website says their case offers 360-degree protection to both you and the phone. They claim to "minimize exposure to radiation being emitted from the phone because the case is integrated with aluminum laminated foil. Together with an aluminum net the composite successfully minimizes your exposure . . ."

Vest Anti Radiation Phone Case

Pong Radiation Protection case: Pong website explains: "Pong cases are embedded with a patented , micro thin, gold plated antenna, that reduces exposure to potentially harmful cell phone radiation while maintaining the phones signal. The Pong antenna couples with the antenna in your phone and redirects radiation away from you."

Pong Case Black Anti Radiation

Reach The Reach Case Site says, " The ReachCase's multi patented, miro-thin antenna automatically couples with your phone to expand and extend your antenna."

Reach Black Phone Case

DefenderShield Cellphone Radiation Case also claims independent testing and says in their website: That a "sophisticated layering of separate non-toxic, human safe materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation-shielding characteristics designed to work in unison to eliminate all radiation emissions from 0 to 10 GHZ and Defender Shield technology refracts, conducts and finally absorbs all these potentially harmful emissions."  In this demonstration, the radiation level measured when DefendeShield case was on is still quite a bit above the level of exposure that I would recommend. I personally do not recommend-holding a phone with a shielding case to your head as the DefenderShield website shows a young woman doing as she demonstrates the product. 

Defender Shield Case Defendershield

ShieldMe  On the ShieldMe site is a message from Wireless Connection CEO Rose Vitale addressing issues with the cellphone industry and she makes some good points.  As far as how ShieldMe works she states, " Our ShieldMe cases help deflect up to 99% of the harmful EMF, RF or microwave radiation emitted from a cellphone while carrying around or when on a call." The demonstration of the SheildMe case shows levels that like the "EMF protection cellphone cases" is many many times higher than levels EMF expert Larry Gust follows as a certified building biologist.   

Shield Me Case Shieldme

    We used a meter that measures the type of EMF–Radio Frequency(RF) Radiation that’s emitted when we use our cellphones or smartphones. 

    Not a Test, A Real World Demo

    Our homemade demonstration of all the cases uses a working phone. Not the shielding material by itself, but the actual "shielding" SafeSleeve, Pong, Reach,  Vest, ShieldMe, and Defender Shield cases. First we get RF power density measurements from a phone that's on a call and then, in the same location, within minutes of the first reading, we place the same phone as it's engaged in a call into each case and we take additional reading with the meter.

    As our video points out: Measurements will vary with signal strength and other factors and that includes ambient energy. I talk about ambient energy in a lot of my videos-it's the energy that's in whatever environment I happen to be measuring in that's coming from a source of wireless energy that isn't the subject of what I'm measuring.  My home is not a lab of course, but fortunately it's always measured very low for RF radiation. 

    Up, Down and All Around

    Moving the meter around the case, we detect readings on the side, back and front of the case. We use the multi-directional TES 593 meter which measures 10 MHz to 8GHz. We use the unit of micro-watts per square centimeter, which looks like this little symbol: μW/cm² and we use it on the max setting which shows the maximum measured value. In non-science speak: the highest level of RF we see, which could be from the back the side or the front. 

    We did not simply measure energy coming from the front of the case which is the area of the case where the phone would be "shielded" from radiation. If we had taken readings with a directional meter, specifically measuring energy coming from only the front or flap cover where the shielding material is, we assume as the manufacturers claim, that we would have seen a drop in the radiation readings.

    However, we measure all around the phone that is in the case because we want to demonstrate what happens as far as wireless energy goes—when you put that baby in your hand.  Or, in your pocket (please don't), or purse, or backpack. 

    The Numbers Please: Did we see lower numbers of overall multi-directional measurements? Sometimes.

    Sometimes the numbers we're higher.  But Don't Worry, This is Tech Wellness and we Have A Solution

    In our demonstration, we see that our naked, non-cased iPhone measures about a 6.2.

    We were super sad to see that not one of the cases reduced that measurement even 20% and a couple of times, we saw measurements actually INCREASE with a case-to the point of doubling the measurement! It was an EMF amplifier.  Watch the video for the full scoop.

    So Hold On—How Can These Cellphone Radiation Blocking Cases Claim they Work?

    Well, look at the information from the Anti-Radiation and Phone Shielding cases websites.  It's kind of tricky, but most are clear about saying the "technology" or the "material" used in the cases is proven by a lab to absorb, deflect or block radiation.

    Ah hah, so to be super-clear they are testing the shielding, absorbing, reflecting and/or signal-interfering material used in the cases. Not the actual cases.

    Here's just one example: The anti-radiation cellphone case company, Safe Sleeve, publishes how the blocking material they use for their cases is certified to block up to 99% of Radio Frequency energy by a certified lab.

    SafeSleeve's report is right up front about showing that they do not test or certify the Safe Sleeve case, rather they are simply testing the material they put into the case in a completely artificial environment, in a laboratory setting, using a signal generator and a power amplifier. Safe Sleeve includes photos showing how the measurements are taken. But that may not be how anyone will ever use their phone.

    Our RF Radiation Reading Was Higher With Some Cases on the phone.

    So of course now that we understand that the cases are not tested and just the material--it makes sense! We measured power density levels all around the case-the shielding material most likely isn't used "all over" because then the phone couldn't receive signal and wouldn't be able to engage in a call.  That's why we did not see even close to a 99% reduction when some cases were on the phone.  In fact, watch the video and you'll see some readings are more than 20% higher with a case on vs the naked phone.


    Can you Trust so called "EMF Experts" who Promote Anti Radiation or EMF Protection phone Cases?  The Government Cautions Us About "Cell Phone Radiation Scams"

    Yeah they do. Both the  FTC and FCC  have warnings against what they call Cellphone Scams—and offer step by step cautions to avoid and reduce the amount of EMF exposure from your smartphone.

    “If you're looking for ways to limit your exposure to the electromagnetic emissions from your cell phone, know that, according to the FTC, there is no scientific proof that so-called shields significantly reduced exposure from these electromagnetic emissions. In fact, products that block only the earpiece—or another small portion of the phone—are totally ineffective because the entire phone emits electromagnetic waves. What's more, these shields may interfere with the phone's signal, cause it to draw even more power to communicate with the base station, and possibly emit more radiation.”

    So What's The Solution to Decrease Cellphone Radiation?

    The point is, even with a modest decreased measurement using a case, it's just not enough to make us happy. So we cannot recommend the SafeSleeve, Pong, Vest, ShieldMe, Alara and Defender Shield cases.

    The real and most guaranteed fix of all, the magic word, one of the solutions we feel passionately about... DISTANCE.

    cellphone shields and anti radiation case review

     Energy plumes, spray or emissions from wireless towers and devices are strongest at the source and dissipate with distance. Watch any of our measurement videos to “see” the invisible RF with our meters.

    Have no fear! There are solutions That really Do work.

    Faraday Cases. A small pocket that protects you from the EMF/RF energy your devices give off. Please know that this will not allow your phone to function, but all signal is blocked, therefore, all EMF is gone when in use. You can use this while walking around (if you’re worried about what your phone emits) or while asleep.

    They also come in all different sizes for your devices. 

    We leave you with this Tech Wellness Mantra: DISTANCE. Be aware, mindful, and caring of the space between yourself and the technology in your life.

    We have a couple of nice options for cases which provide you distance from your smartphone or cellphone. We LOVE both of these cases for two reasons:

    • EXTRA LONG crossbody strap.  This strap allows your phone to be a full 8" to 12" from your reproductive organs.  So important!  Most crossbody cellphone cases lay right over your abdomen.  Not good.
    • WE INCLUDE a double Wristlet chain so the phone can dangle 8 inches from your wrist.  LOVELY

    Cellphone Crossbody Case with Wristlet

    Wireless EMF Energy vs. Body Energy

    August has been doing EMF measurement videos on cell phones and mobile phones since 2000 because she wanted to show people the "energy waves" that can't be seen, felt or touched.

    In many of the videos, she pointed out that the energy coming from a Smartphone or a Bluetooth speaker, negatively affected the energy of her body. She felt that the wireless energy wasn't interacting with her body's energy in a good way.

    So How Much Wireless Energy is Too Much?

    Well let's start here: the Environmental Health Trust points out, "science has not yet determined a safe level of wireless radiation." Bummer. 

    Our recommendation is to reduce your exposure from wireless sources. We advocate what’s referred to as the Precautionary Principle. Basically, this means that because there’s research, lots of it actually, saying the energy that powers our cellphones (RF radiation) could be causing health concerns like tumors and cancer. We ought to take care when using our cell phones and all devices that emit RF, using them mindfully.

    The International Institute of Building Biology has Building Biology Standards for Electromagnetic Sensitive people and to what degree they should limit exposure to in rooms where they sleep. The levels we detected in our anti-radiation cellphone case review were MUCH higher. 

    In a real-world setting, August, having ES herself, hopes people who are trying to control their exposures, will refer to the following chart:

    EMF Radiation: A Guide for You and Your Family

    If you think EMF Radiation is messing with the energy in your body, please visit our complete EMF Radiation, Wireless Energy and Electrosmog Guide.

    It contains a detailed list of symptoms from people who report how they feel when exposed to wireless energy.  Here's a sample:

    • Insomnia and sleep issues
    • Headaches and head pain
    • Tinnitus or ringing in the ears
    • Lethargy and extreme tiredness
    • Memory, fog, cognitive issues
    • Burning, tingling, numbness

    Let's Hear from an Expert in the EMF Radiation Space

    We asked Dr. George Carlo his thoughts on EMF cases and shielding products, “most offer some protection, some of the time, to some people, because they can alter the immediate electromagnetic field environment around the person,” and immediately emphasizes the importance of “some,” which seems to tell us that it’s vastly unpredictable. “All waveforms in the environment are highly variable and they interact with other factors in the environment that make them even more variable.” This pretty much sums up that the artificial electromagnetic energy universe is vastly unpredictable.

    "To expect relief from radiation exposure from one specific device, is nearly impossible. It’s crucial to weigh in the MANY environmental factors; such as, temperature, atmospheric pressure, other radio waves, emissions from other devices, energy shifts from others around you, and Schumann Resonance shifts. Therefore," he explains that “relying on alteration of the environment as a safety precaution is always a game of chance…and signals affect people differently,” which adds another variables in the game of chance.

    Dr. Carlo, wrote a  Medical Alert ten years ago. He cautioned people with EMF sensitivity against relying upon widely-available EMR Protection Products to prevent the effects of EMF exposure. He noted that EMF sensitive individuals were reporting the opposite effect: people found their symptoms and/or sensitivity worsened. Specifically, severe “symptom relapses.” Dr. Carlo noted:

    “When symptoms are not addressed comprehensively– for example, using symptom amelioration without simultaneous elimination of exposure – cell membrane adverse reaction and damage continue to occur while the patient is assuming the cause of the problem has been eliminated. This lulls patients into a false sense of security, causing them to aggravate their exposures through the increased use of their wireless devices. When the damage reaches a critically harmful level, even the symptom amelioration can no longer be sustained by the damaged cells.”

    We really do not recommend any kind of chip, guard, anti-radiation "filters" or incomplete shielding case because honestly, how could they NOT provide a false sense of security? Folks could believe these products make them “invincible” against radiation so they are comfortable holding the case right up to their heads-and the radiation seeping from the back and the side of the phone case is in very close proximity to their precious brains. Oh no!

    Let us know what you think.  We always love your ideas and comments! We can live mindfully with our technology as long as we know the options and what really truly works. 

    If you found this honest review helpful, we hope you'll share it with someone your care about.

    And Please . . .

    Be Well!

    Here's research showing the effects of EMF radiation


    • With the Faraday cage pockets, are those any different than just putting your phone in Airplane mode?
      I’m looking for something to use on walks while I push the stroller. Right now I just put my phone in Airplane mode and put it in the cup holder on the stroller. But if I’m waiting for a phone call or my husband might need to get a hold of me, I’d like to use a pouch that can block most of the signal but allow enough to receive a phone call and then I could take it out of the pouch. Is there a product like this? That blocks almost all, but still allows a phone call to come in?

    • I wish this article showed a reading with the August case to show 100% radiation reduction.

    • Thank you for your comments and contact information SafeSleeve. We will reach out to you via email. As always at Tech Wellness our mission is to help people achieve a healthy relationship with technology.

      Tech Wellness
    • Thanks for that, SafeSleeve. Super helpful. Ordering one now.

    • Hi August and Tech Wellness Team. We at SafeSleeve salute you for your effort to educate and provide solutions for the hidden dangers of EMF radiation exposure from wireless electronics. Like you, we’ve worked extremely hard to provide a practical solution for EMF exposure and, as verified by our independent lab testing, we believe we’ve found an extremely effective and practical solution. While I cannot speak for the other devices you tested here, there are some key points about our SafeSleeve technology that we wanted to make sure you took into consideration:

      1. Our technology does not eliminate radiation emissions from the device. To your point, this would render the device useless.

      2. Our products are designed to provide an anti-radiation barrier between the device and the body. This way, the devices are still usable and able to send and receive signal out of the non-shielded side while shielding the EMF away from the body. Because of this, you will only see a reduction in EMF levels on the shielded side of the device. The test you have conducted shows the highest levels from anywhere around the device.

      3. A lab setting is the only legitimate way to show the effectiveness of our technology for a few main reasons: one, a controlled source is the only way to conduct a scientific study. Note that the controlled source that we used was specifically designed to simulate emissions from wireless electronics (RF and ELF emissions of various frequencies). Two, ambient levels in a non-controlled environment will affect readings, rendering the results inaccurate. Three, at-home equipment such as the meter used in the video is not suitable for the types of emissions by a wireless device, nor are they reliable.

      4. For the reasons mentioned in #3 above, an at-home meter test is extremely inaccurate and unreliable. That said, a far field RF meter such as the one you are using is highly influenced by ambient RF levels that exist almost everywhere. Again, we do not aim to eliminate the radiation from the device, nor from your surroundings, but our technology does deflect the radiation away from the body.

      You hit the nail on the head when you say that distance is key when it comes to EMF exposure. The solutions you sell will definitely help provide that separation. That said, our products are different in that they shield the user from EMF while allowing them to use the device as they normally would, without needing to hold their device by a rope or placing it in a faraday cage that eliminates signal altogether.

      All of that being said, we hope you will reconsider your testing methods and recommendations.
