What are Faraday bags and how do they work?

1. How do Faraday bags work?

Faraday bags are lined with layers of conductive mesh material (like silver, copper, etc.) that block signals from reaching the items within the bag. The mesh conducts electric currents around the item you’re protecting.

This means cellular signals, WiFi, Bluetooth, 5G, RFID, etc can’t connect to your phone. The holes in the mesh have to be small enough so electric waves can’t go through them and it has to completely seal to block out all currents. 

It protect devices from radio frequency (RF) signals or from electromagnetic pulses (EMPs). And blocks hackers or larger bodies from tracking your location, hacking into your personal or work information. It also keeps EMFs away from your body.

Your bag or pouch is a variation of the Faraday cage (discovered in the 1800s) that is small enough to be portable but still using the same types of conductive materials to block signals from reaching inside the cage.

2. How well do they work?

These bags and pouches are used by the military, police, government leaders, corporate leaders, and other people deemed important. If they’re using them then you know they work.

Besides that there’s a ton of research and testing on the bags, lots of reviews from people very happy with them, and you can test them out yourself easily.

Faraday cages are used in important laboratories for delicate research that can’t be affected by any energetic waves or EMFs.

It’s important to note that they do not work if you don’t properly close your bag, if there’s an opening to the cage itself, signals can get in. And they can degrade overtime so it’s important to test yours if you’ve had it for a while.

3. How do I know if it’s working?

Here are a few ways to tell if your bag is shielding effectively:

1. Check for a tight seal: Make sure that the bag is properly sealed so that no outside EMF can enter (some bags are velcro, others roll to close, some have extra buckles).
2. Try calling or texting your phone after it is placed in the bag.
3. Turn Bluetooth on and try to pair with the items (smartwatch, laptop, fitness tracker, phone) inside your bag.
4. Use an EMF Meter on the outside of your bag. Your reading should be near zero (although that depends on what else is around you too).

You should feel pretty confident your bag is working, if you picked one of my top recommendations but these steps give you a clear picture of whether it’s blocking outside electromagnetic fields and signals or not.

4. Why should I use a Faraday bag?

These bags have so many benefits and uses, including;

• Reducing electromagnetic radiation exposure
• Preventing personal data loss from hackers
• Protecting electronic devices from EMPs
• Shielding electronic devices from RFID skimming
• Increasing the lifespan of electronic devices
• Blocking location tracking
• Keeping work information and financials secure
