We say unknown not because the public is unaware of EMF, but that the long-term consequences of EMF exposure are unknown. Maybe it will all be OK and not a big deal, or perhaps looking back we will see a slew of health problems that develop from EMF exposure over time.

There are some documented effects that sensitive people experience, such as headaches and sleep disturbances. So, protecting yourself, just in case, is a good idea.

We know many of you are thinking, “yeah, EMF protection gear is for yuppies with disposable income. What’s an average person like me supposed to do? I can’t afford any of that stuff.” Well, we’re here to tell you never fear, there are effective and affordable anti-EMF products out there.

Our Best Affordable EMF Blocker Reviews and Comparisons

1.DefenderShield Universal EMF Protection & Radiation-Blocking Cell Phone Case

Product Highlights

The DefenderShield Universal Cell Phone Case is a one-size-fits-all EMF-blocking cell phone case that works with all Android phones and does a decent job at fitting iPhones. The case is made of a “vegan leather” (polyurethane) shell with a textured rubber interior and is well-stitched.

DefenderShield cases use silver fabric which can block 99% of EMF and work up to the 10 GHz band (which cover most of 5G transmissions) and includes several handy features such as a detachable wrist strap, a detachable card wallet for three cards, and an RFID shielding layer including their proprietary shielding materials. Shielding is on the underside of the case, away from the side with the phone, to absorb and dissipate EMF without interfering with cell phone communication.

The cases come in small (5.7 by 3 inches) and large sizes (6.5 by 3.2 inches) and can accommodate up to the largest android cell phones on the market.

Features

  • EMF-blocking shields 99% of emissions up to 10 GHz
  • A vegan leather outer shell
  • Removable RFID-shielded card wallet is detachable
  • Detachable wrist strap

What We Like About DefenderShield Universal EMF Protection & Radiation-Blocking Cell Phone Case

This is our top pick for an affordable anti-EMF cell phone case. Not that the others on this list are not affordable and effective, but this phone case functions as a wallet-style case, which means it is easy to use.

Other cases are actually sleeves, which requires the user to take the phone out to use it. This case by DefenderShield looks and functions just like a regular cell phone case.

DefenderShield cases can block frequencies up into the 5G range (10 GHz) does so effectively, to 99% shielded energies in the peak the frequency range of the case. This is a normal-looking cell phone case with all the safety features.

What We Don’t Like About DefenderShield Universal EMF Protection & Radiation-Blocking Cell Phone Case

There is no cut-out window for a cell phone camera lens since these cases are universal cases. Since the position of camera lenses on cell phones varies, there is no way to make a universal case that can accommodate all cell phones on the market. There are also some issues with fit since these are universal cases and different phone models can be used.

PROS

  • Very well-made
  • Cases have been laboratory-tested (blocks 99% of EMF)
  • Detachable card wallet holds 3 cards
  • RFID protection shielding in the card wallet

CONS

  • No window for the cell phone camera
  • Some phone models fit loosely

2. SYB Phone Pouch

Product Highlights

The Phone Pouch by SYB is an EMF-shielding cell phone case but is more in design like a sleeve you would use to cover your tablet. The construction is a flexible and durable (the edges are serger-stitched) neoprene rubber fabric with nickel/cobalt alloy thread interwoven in the polyester lining.

You can purchase the pouch in different sizes for different models of cell phones and the Phone Pouch also comes in a variety of color options (red, green, orange, blue, and black). There is a wide belt loop on one side which can be attached to a belt or backpack strap.

The top of the pouch is open so there is no interference with call reception and also allows access for a wired headset. The Phone Pouch has been laboratory-tested and is certified to block 99.9% EMF to an upper limit of 20 GHz frequency, which covers most of the 5G band.

Features

  • Blocks EMF (99.9% up to 20 GHz)
  • Phone can be used while in the pouch
  • The case is soft and flexible
  • Belt loop (good for walking or sports)

v

What We Like About SYB Phone Pouch

The build of this no-fuss pouch is strong and the stitching tight. With soft sides, the pouch is convenient to carry or wear on your belt.

Choosing the right pouch size, the phone stays snugly seated and can be carried safely during exercise. The shielding used (nickel/cobalt) works extremely well.

What We Don’t Like About SYB Phone Pouch

The padded sides and snug fit can cause cell phones to heat up during use (such as being on a long call or using the phone to run a playlist). There are some user reviews that claim the pouch does not work.

One video was posted with a customer using a Meterk EMF meter to take measurements, pointing it at the open end of the pouch. They showed that they received a signal and claimed that the pouch does not block EMF.

First of all, that EMF meter does not measure frequencies in the cell phone communications bands but is intended to survey electrical equipment. Secondly, there is no shielding on the pouch top anyway.

PROS

  • Blocks EMF to over 99%
  • Comfortable to wear or carry
  • Belt loop for use while walking or exercising
  • Plenty of color options

CONS

  • Cell phone heating issues

3. RadiArmor Anti-Radiation Cell Phone Sleeve

Product Highlights

The Anti-Radiation Cell Phone Sleeve by RadiArmor is a neoprene pouch that incorporates anti-EMF shielding material (likely a silver thread) on the backside (user side). The company claims that it will block between 91% and 96% of EMF, depending on frequency but functions up into the 5G band.

The sleeve only comes in one size, 7.1 by 4.15 inches, that fits most cell phones including larger phones such as the Samsung S10 Galaxy. The design differs from the SYB Phone Pouch in that there is a fold-over flap with Velcro closure at the top.

Verifying any of these claims or the nature of the EMF material is difficult since RadiArmor blocks access to its company website (which we have always found to be very curious).

Features

  • Blocks 91-96% of EMF
  • Fold-over flap closure
  • One size fits all
  • Belt loop for easy carry

What We Like About RadiArmor Anti-Radiation Cell Phone Sleeve

The pouch is a soft-sided sleeve and comfortable to carry. The top flap is also very convenient for keeping the phone in place while walking or playing sports.

What We Don’t Like About RadiArmor Anti-Radiation Cell Phone Sleeve

The sleeve is only one size, so some phones are not held with a snug fit (that is the reason for the top flap). The pouch can cause phones to heat up during extended use, such as while on a long call or while playing music.

PROS

  • Soft and comfortable to wear
  • Blocks 91-96% of EMF
  • Fold-over top flap
  • Belt loop

CONS

  • Phones can heat up in the pouch

4. SYB 5G Phone Shield

Product Highlights

The SYB 5G Phone Shield resembles a cell phone case as it has the same dimensions as one, but does not mount to the phone. The Phone Shield is a plank or shim that is placed between the user and their body in a shirt, jacket, or pants pocket while carrying the phone on standby.

The shield is made with medium brown vegan leather (polyurethane), stitched tightly around a layer of silver-woven shielding fabric. It is basically a small Faraday cage or guard and works rather well when properly placed.

Approximately 99% of EMF is blocked by the shield up to a frequency limit of 20 GHz.

Features

  • EMF is blocked at 99% up to 20 GHz frequency
  • Shielding is made from silver fabric
  • Comes in several sizes for any size phone

What We Like About SYB 5G Phone Shield

If you place the Phone Shield properly behind your phone while it sits in standby in your pocket, 99% of EMF is shielded from the user. This is a great product for people who hate phone cases and find them too bulky, but want some level of EMF protection while carrying around their phone while it is on.

Limitations of other universal phone cases with respect to camera lens access are solved with this product since it is not a case and can easily be separated from the phone when you want to snap a pic.

What We Don’t Like About SYB 5G Phone Shield

A survey of user comments revealed no negatives about the Phone Shield. Many commented that they are satisfied with their performance and being lightweight.

PROS

  • Weighs very little
  • Nice appearance
  • Blocks 99% of EMF
  • No interference with cell phone cameras

CONS

  • None

5. SYB Pocket Patch

Product Highlights

For people who want some EMF shielding while carrying their cell phone on standby, but who want something a bit more permanent in a solution without having to use a bulky cell phone case, then the Pocket Patch by SYB was made for you. This product is similar in many ways to their Phone Shield, but this is more of a wearable permanent fix.

The Pocket Patch is a phone shield patch with a waterproof adhesive backing that allows users to affix the shield to the backside of any pants, shirt, or jacket pocket. The Pocket Patch is made from hypoallergenic cotton with embedded silver thread.

Once attached to your garment, it becomes a permanent part and can withstand laundering (without bleach) and wear. You can also toss your pocket-patched garments in the dryer with no worries.

At the higher frequency end of 3 GHz, approximately 87.4% of EMF is blocked and that increases to close to 98% for frequencies lower than 2.1 GHz.

Features

  • Permanent adhesive patch (comes in a set of 3)
  • Blocks 85-98% of EMF up to 3 GHz
  • Soft, not stiff
  • Altered garments can be laundered and dried

What We Like About SYB Pocket Patch

We like the idea of a permanent fix to EMF exposure from your cell phone while carrying it around. If you hate phone cases (many of us do!) and worry about forgetting to grab an EMF-shielding shim when you go out, this is a great solution. The fact that your anti-EMF garments can be washed and dried normally like regular clothing is a big bonus. Just don’t use bleach.

What We Don’t Like About SYB Pocket Patch

There were some reports of users testing the patches and reporting that they do not work. However, they were affixing the patches to the phones, not to a garment.

That may seem like a technicality, but covering the phone with shielding can boost signal output from the phone as it tries to transmit around the shield to connect to a cell tower. Other user test videos that claim product ineffectiveness use popular EMF meters that are actually not designed to detect signals in the cell phone band.

In short, most people do not understand enough about the technologies they play with daily.

PROS

  • Comes in a 3-pack
  • Wash and dry your patched garments normally
  • A simple solution

CONS

  • Patches must be matched to pocket size, else the phone may shift past the shielding

6. RadiArmor EMF-Blocking Hat

Product Highlights

Using a cell phone with shielding provides a good level of protection, but what about other sources of EMF? The RadiArmor EMF-Blocking Hat is a black baseball-style cap that looks like a great piece of urban wear with all the cool points.

You can wear the cap to protect your brain when using your cell phone or from environmental EMF while you travel about town. RadiArmor reports that the cap will block 99% of EMF but field evaluations by other researchers show that value to be more like 90%, still a good reduction.

Made from 100% cotton, the cap is a 6-panel style without eyelets and has a small logo stitched in front. The back strap is cloth with a buckle clamp and is a higher quality and nicer build than a plastic strip.

The inner shell of the cap is where you find the EMF shielding, which is made from silver fabric. RadiArmor also claims that the silver resists bacterial growth, meaning the cap does not need to be cleaned regularly.

Features

  • One size fits all (up to 22.25 inches)
  • Silver EMF shield blocks 99% EMF (actually 90%)
  • Cool urban wear
  • Stitched logo is a subtle bit of bling

What We Like About RadiArmor EMF-Blocking Hat

This EMF-blocking hat looks great and functions well as urban wear. The style elements indicate that this is a high-quality cap and the lack of eyelets gives it more of a sleek, dressed-up look.

The cloth back strap with buckle also is more refined than a plastic strip back strap and we feel is an excellent design choice.

What We Don’t Like About RadiArmor EMF-Blocking Hat

Size is an issue to be addressed here, as the cap can only accommodate heads up to 22.25 inches in circumference (equivalent to a 7 1/8 hat size). This means it is a cap for people with small to medium heads.

We also did not like the fact that RadiArmor does not share its testing results, since they block access to their corporate website. No idea why they have one if nobody can visit it.

PROS

  • Looks cool
  • The backstrap is cloth, not plastic
  • Blocks 90% of EMF
  • Antibacterial

CONS

  • Sizing limits (only up to medium size; 7 1/8 inch)
  • Lack of corporate transparency

7. Blair EMF Radiation Protection Baseball Cap

Product Highlights

The EMF Radiation Protection Baseball Cap by Blair is a 6-panel baseball-style cap with top panel eyelets, curved bill, and nice accent piping on the bill edge. The hat is offered in three color schemes: black with red piping, navy blue with white piping, and sky blue with white piping.

The backstrap is cloth and adjusts by a Velcro closure. The inner liner of the cap contains an anti-EMF fabric, which is a silver fabric.

The hat fits head sizes up to 25.2 inches circumference (hat size 8) Blair claims that up to 99% of EMF is blocked by the hat, but does not list through what frequencies this occurs nor do they share their testing data (actually, Blair blocks access to their corporate website, which is curious as to how they do customer service).

Features

  • Blocks 99% of EMF
  • Cloth backstrap with Velcro closure
  • Comes in three colors

What We Like About Blair EMF Radiation Protection Baseball Cap

We like the looks of the Blair cap. The edge piping on the bill is a nice touch. Customers also seem satisfied with the comfort and fit of the cap.

What We Don’t Like About Blair EMF Radiation Protection Baseball Cap

Customer service is terrible with Blair. They have a corporate website that is referenced by their parent company (Bluestem Brands) but blocks outsiders from access.

If you need to return your hat and have purchased it through Amazon, you have to return it to them through Amazon.

PROS

  • Cool points on the colors and piping schemes
  • Great looking EMF blocker
  • Comfortable backstrap

CONS

  • Velcro on backstrap will eventually wear out
  • No customer service

FINAL VERDICT

For our final wrap up, here are the recommendations for each category.

Cell phone case: Go with DefenderShield.

Looks like a regular phone case, works like a regular phone case. If you have to take a pick, just take the phone out for a few minutes.

Shields: SYB Pocket Patch. Sure, it’s permanent, but you can wash it too.

Hats: RadiArmor cap. Comfortable, well-made, and stylish. If you have a big head (or a lot of hair), then the Blair cap is a good alternative.
