At RF Safe we stick to the laws of physics, even if it limits our appeal because we refuse to compromise your safety.

The QuantaCase product line is designed for those seeking to minimize their exposure to radiation from smartphones. This ultra-thin and sleek phone case is meticulously engineered to ensure the lowest possible radiation output, blending advanced technology with a stylish design.

About this item

Enhance your style while safeguarding against cell phone radiation with the RF Safe QuantaCase™. This sleek and discreet case provides essential RF radiation protection precisely where it’s needed most. Beyond just being a stylish accessory or a protective cover for your phone, the RF Safe QuantaCase™ prioritizes what matters most—reducing the amount of radiation absorbed by your head and body.

Important Consideration

Only purchase the QuantaCase if you seek a meticulously crafted, ultra-thin, and sleek phone radiation mitigation solution that aims to minimize your radiation exposure while ensuring the lowest possible radiation output from your device.

Design Precision

Whether the QuantaCase incorporates a specific design feature or lacks one, every detail is intentional. Each element is purposefully chosen to prioritize minimizing radiation exposure.

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.

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.

Shielded Speaker Hole

While many anti-radiation cases feature unshielded speaker holes, compromising shielding at higher gigahertz spectrums typical of 5G and new satellite communication features, QuantaCase stands out. It boasts a uniquely shielded speaker hole, designed for the 5G era. This not only ensures enhanced radiation protection but also allows users to easily verify the shielding’s conductivity with a simple Ohmmeter. In comparison, competitor cases would need to be torn apart for the same test. QuantaCase delivers superior protection and transparency in one compact design.

Why Just One RFID-Blocking Slot? Insights from 25 Years of Experience

QuantaCase’s decision to incorporate a single RFID-blocking card slot is rooted in two and a half decades of knowledge and research. RF shielding is most effective when perfectly aligned with the device’s front, ensuring minimal out-of-parallelism. Over the years, one slot has proven optimal, allowing users to isolate temporary-use RFID cards like hotel room keys, ensuring minimal exposure to personal credit card details.

The Downside of Wallet Features – Too many slots

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.

Flip the front cover to the rear of the phone for speakerphone use

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.

Why QuantaCase Is So Thin? Science Meets Design

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.

Usage Guidelines to Maximize 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.

By following these simple guidelines, you can maximize the benefits of the QuantaCase and ensure you’re minimizing radiation exposure during everyday phone use.

How does it work?

Most materials are transparent to microwave radiation from smartphone devices.  As a result, microwave energy is absorbed into a user’s body closest to where the cell phone is being carried or used.  The QuantaCase™uses specially placed materials that deflect the most intense microwave radiation from smartphone devices away from you.

When a phone is used with a heads-free device, and the phone is carried in your pocket, radiant energy is absorbed much faster than at the head because tissues and organs such as the liver, kidneys, or reproductive organs provide much better conductivity than the skull and simply put most of your body’s major organs have no bone protection as the brain does.

The essential requirement of any cell phone radiation shielding is that it is electrically conductive.  The QuantaCase™ anti-radiation phone case is lined with highly conductive RF shielding materials designed to deflect cell phone radiation away from your body.    Testing the conductivity of shielding material inside the QuantaCase™ is an inexpensive way to verify the material being used supports the physics necessary to reflect microwaves and provide a conductive barrier between your smartphone and your body.

Materials Used for Electromagnetic Radiation Shielding

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.  Absorption (attenuation) is never used to prevent affecting the phone’s software regulating RF power output.  RF Safe only uses absorption technologies on wires (Ferrite Beads), such as on an air-tube headset plugged into your phone.

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.
