If the physics says a phone case shouldn’t have metal loops and detachable magnets because the phone’s software responds by increasing power when obstructed, then it shouldn’t have them. The design of QuantaCase is guided by what is harmful or not, not by what sells best. At RF Safe we stick to the laws of physics, even if it limits our appeal because we refuse to compromise your safety.

Look for a complete shielded cover - no holes!

No Metal Loops

Unlike most so-called anti-radiation phone cases, a real anti-radiation case like QuantaCase deliberately excludes metal carrying strap loops. Metal loops near the phone’s antenna can instigate unpredictable radiation flux patterns around the head, increasing potential risks. For those concerned about radiation exposure, it’s essential to understand the consequences of metal elements near a phone’s antenna.

The Downside of Using Wallet Features

Using your anti-radiation phone case as a wallet might seem convenient, but it significantly reduces the effectiveness of the radiation shielding. Here’s why:

  • Discouraged Proper Use: The added bulk of cards and money discourages users from flipping the cover inside out, which is necessary for optimal radiation protection during texting and speakerphone use.
  • Compromised Shielding: When the shielding material isn’t positioned correctly, it fails to protect your hand from radiation, leading to increased exposure.


Choose Safety First

This GIF demonstrates QuantaCase’s unique multi-position design, showcasing how the shielded front cover can easily be positioned at the back of the phone to maintain shielding between the hand and the device during speakerphone use. The side latch design ensures the phone remains securely in your hand without needing to grasp the sides, which is especially beneficial for individuals with electromagnetic hypersensitivity (EHS). This feature allows for safer, more comfortable handling of the phone while minimizing radiation exposure.

Non-Detachable Design

Unlike other so-called anti-radiation phone case companies, QuantaCase stands apart because we refuse to make a non-detachable design.  We know better! This choice ensures that there’s no escalation in RF exposure due to the interference of metal plates and magnets with the phone’s antenna. Before investing in a detachable anti-radiation phone case, it’s crucial to research and comprehend how phone radiation levels can increase in the presence of detachable components. Making informed choices is key to maximizing protection.

During Calls When Held To Ear

After initiating or receiving a call, close the radiation-shielding front flap. Continue your conversation normally with the shielded cover between the body and the device – the microphone and speaker are fully functional for private calls. However, opt for the speakerphone feature when feasible for added safety.

Storing in Your Pocket

Ensure the shielded front flap faces your body. Back pocket preferred. This deflects the most potent line-of-sight radiation away, offering you added protection.


For text communications, fold the flap behind the phone. This shields the device’s back where the antennas are located while you hold it, providing protection for your hand without compromising radiation safety for the rest of your body due to the maintained distance.

How to use your anti-radiation phone case

Why QuantaCase Is So Thin? 

You ever noticed how tree leaves can disrupt 5G signals? It’s due to 5G’s shorter high-frequency wavelengths being easily obstructed. With this in mind, RF Safe’s QuantaCase is purposefully the thinnest anti-radiation case out there. A thicker case might cause phones to increase output power to maintain an optimal connection to the tower, leading to more radiation. QuantaCase ensures optimal signal strength while minimizing radiation exposure, blending sleekness with safety

Side Latch

QuantaCase has introduced a unique one-finger side latch that goes beyond aesthetics. This feature is designed for easy use with either a thumb or finger and offers enhanced safety by placing the user’s digit away from the phone’s radiation-emitting sections. Apart from keeping the front shielded cover intact, it adds a protective gap between the user and the phone without boosting output power. The design underscores QuantaCase’s dedication to blending style with health-focused functionality.

QuantaCase’s Built-in Stand to Maximize Safety with Distance

The QuantaCase isn’t just about shielding; it’s about proactive protection. Equipped with a built-in landscape view stand, it ensures you can easily maintain a safe distance from your device, especially during data-intensive tasks like streaming. Phones can emit more radiation when demanding more data, so next time you’re about to watch a high-resolution video, deploy the QuantaCase stand. Enjoy your content from a safe distance of at least a couple of feet. With QuantaCase, you get the optimal blend of convenience and protection.

Thin Design

RF Shielded fabric is made from polyester filaments woven with a blend of micro-fine conductive threads.  The shielding fabric is combined with a proprietary process for deflecting potentially harmful radiation.

RF Safe QuantaCase™ Shielding Mesh is visible inside the earpiece speaker hole, which allows the metal alloys used in the RF shielding to be tested for conductivity.

Designed to deflect radiation from smartphones

The RF Safe QuantaCase™ only incorporates shielding mechanisms that utilize deflection.

How QuantaCase™ Electromagnetic Radiation Shielding Works

Electromagnetic radiation consists of coupled electric and magnetic fields.  The electric field produces forces on the charge carriers (i.e., electrons) within the conductor.  As soon as an electric field is applied to the surface of an ideal conductor, it induces a current that causes charge displacement inside the conductor that cancels the applied field inside, at which point the current stops.

Varying magnetic fields generate eddy currents that repel the applied magnetic fields.  The result is that electromagnetic radiation is reflected from the conductor’s surface.

QuantaCase™ deflects phone radiation, as shown in the illustration.  By simply keeping the shielded flip cover between your body and device, whether used to your ear or carried in your pocket or in the palm of your hand using speakerphone – you have the shielding you need to cover the entire surface area of the phone to deflect potentially harmful excess radiation from being absorbed into the body.

RF Safe Phone Shielding

The inclusion of multiple card slots and wallet features in a phone case might seem convenient but it can significantly reduce the effectiveness of radiation shielding. When the phone case is used as a wallet, it discourages proper use of the shielding during texting or speakerphone mode. The added bulk of cards and money makes it less likely that users will flip the cover inside out, which is necessary for optimal radiation protection. By limiting to one RFID-blocking slot, QuantaCase ensures users can maintain the correct use of the shielding, thereby maximizing safety.

So-called “anti-radiation” phone cases

The market is flooded with so-called “anti-radiation” phone cases that promise protection but don’t deliver. Take SafeSleeve and DefenderShield, for example. These brands claim to protect you from harmful radiation with detachable cases but include design flaws that can actually increase your exposure. Metal plates and magnets obstruct the phone’s antenna, causing it to emit even more radiation to maintain connectivity.

The FTC has already issued warnings about such scams, but consumers keep falling for them. Why? Because consumers are not doing their homework or demanding real solutions and transparency. Here is a chart to help clarify why QuantaCase is in a league of its own. QuantaCase is the world’s only genuine anti-radiation phone case backed by decades of RF Safe design experience.

Here is a comprehensive comparison to help clarify why QuantaCase stands out from the crowd in the market for cell phone radiation blocker cases.
