SafeSleeve FAQs

1. What is the shielding material made of?

SafeSleeve shielding material is made of a lightweight, lead-free metallic alloy foil, specially engineered to block all three types of radiation emitted by your devices (ELF, RF and Thermal).

2. Do you have testing that proves that it works?

Yes. Our radiation shielding technology was tested in an independent FCC accredited lab to show reductions in EMR of up to 99%. You can see the study here. 

3. How does the cell phone case protect me from radiation?

The shielding material in the front flap blocks EMR from your phone. When you receive a phone call, simply open the flap, answer, close the flap back up and talk as you normally would with no reduction in sound quality on either end. When placing in your pocket, position the flap side towards your body.

4. Why is the shielding material only in the front flap?

Our shielding technology is incorporated into the front flap as to provide protection in the direction of your body while still allowing signal to enter and exit the phone through the back panel. If we were to shield the sides and back, the phone would no longer be able to send and receive a signal. That said, close the flap when on a call and position the phone so that the front flap faces you when in your pocket. Note that the flap can be folded behind the phone or tablet to shield the part of the device closest to your body while in use.

5. Do you need a flap?

Incorporating the shielding technology into the front flap provides a radiation barrier between you and your phone or tablet. Other products claim to provide the same protection without a flap (snap on case or radiation absorbing sticker/pendant), but we believe a flap to be the only effective means of providing true protection from all types of EMR radiation. For both the phone and tablet, the flap can be positioned between yourself and the part of the device closest to your body.

6. Can I use a tri-field meter to measure the radiation from my phone or tablet?

In order to accurately and reliably measure radiation levels and reductions, testing must be performed in a controlled laboratory setting with highly specialized equipment. SafeSleeve had an independent, FCC accredited lab test their shielding technology and the results were impressive. Not only can it block over 99% of RF, it can also block 92% of ELF See the full results here

Although unreliable, a tri-field meter may show some reductions as can be seen in the product video.

7. How is my phone held in place?

Your phone easily snaps in and out of a silicone inner shell that is custom fit per type of phone. Our universal cell phone cases use an adhesive pad to hold the phone in place.

8. I just got my case and it is hard to close the flap and magnetic latch. Is it defective?

The premium materials we use are stretched tightly during assembly to ensure quality and durability. Thus, it may take a day or two for the materials to wear in to where the case will easily close and stay closed with several cards inside.

9. How does the laptop case protect me from radiation?

Simply place your laptop on your SafeSleeve Laptop Case or Lap Desk (either side up) as an anti-radiation barrier between you and your computer. Our shielding material spans the entire area of the case and lap desk.

10. What about the top and sides of my computer?

Some EMR is emitted from the top of the computer, but vital areas of your body (i.e. chest, abdomen and head) are at a safe distance (6-8 inches) from the laptop. While your hands and wrists are in this range, they are far less susceptible since they do not have the same soft tissues and vascularity as your lap. Levels around the sides of the laptop are negligible as seen by using a tri-field EMF meter.
