Do EMF protection devices work?


Do EMF protection devices work?

Do EMF protection devices work? It would be easy for us just to say “Yes.” Okay, you are thinking, but how do EMF protection devices work?

If you are wondering whether EMF protection devices work, or more to the point, how EMF protection devices work, let’s find out.

It’s all based on an old, well known scientific principle: the Faraday cage. It’s a metallic enclosure that prevents electricity or electrical impulses – like mobile phone radiation which uses an electromagnetic field – from travelling in or out.  

How do EMF protection devices work?

The Faraday cage is named after the British scientist Michael Faraday, who discovered how it worked in the late 1800s. It’s a technology that is used a lot, but we don’t always realise it. How Stuff Works has an entertaining and informative article on the Faraday cage, tracing its history, the science and its uses.

Some cinemas deploy building wide technology that is in effect a Faraday cage. This is to stop you from receiving mobile phone signal. Or you might have to seal your phone in a Faraday sleeve – the same idea, but more an envelope than a cage – if you are attending a top secret event like attendees at the recent Star Wars premiere had to.

Faraday sleeves are getting popular to stop electronic car keys from being hacked. Or to cloak your phone’s GPS signal and obscure your whereabouts. Conspiracy theorists might make a DIY Faraday cage to protect their electrical devices in case of World War III or an EMP attack.

But WaveWall cases aren’t a full cage. They are open on one side, which means that your phone, iPad or laptop can still connect to the network or wifi and work normally. The side nearest your body is shielded and the radiation bounces right off. What it bounces off is the finely woven metallic mesh in the fabric – the Faraday cage.

So, do EMF protection devices work? Absolutely, and WaveWall uses patent pending EMF protection technology for our range of EMF protection devices. Independent testing has shown it blocks up to 87% of mobile phone radiation.
