EMF Shielding: In-Depth Guide for Home Protection

We can’t see EMF, but this doesn’t mean it isn’t harmful to us. If you are reading this article, you may already be aware of EMF dangers. Smart gadgets we use in our everyday life emit radiation that is harmful to humans and animals in many ways. As a matter of fact, the smartphone or laptop you are using to read this article is emitting radiation right now.

In the same way, smart meters, WiFi routers, and other smart devices in our homes emit EMF that affects our health and lifestyle in adverse ways. We can’t stop using these products, but we can reduce the chances of exposure to EMF to minimize health dangers. This is the reason why the practice of EMF shielding is becoming more and more popular with time. In this article, we are going to discuss what EMF shielding is and how it works.

What is EMF Shielding

EMF shielding is the practice of reducing EMF in a particular region or space by using blocking materials that serve as a barrier. You can isolate the devices that emit EMF from their surroundings to reduce the harmful effects. EMF blocking materials can attenuate the radiation by up to 99%, which is an impressive thing as it makes the surroundings safe for people.

Without proper shielding, we aren’t safe even in our bedrooms, which is a matter of concern. Our smartphones don’t stop emitting radiation even when we are sleeping, which means we are still exposed to EMF. Well, we can turn on the Airplane mode of the device and turn off WiFi routers, but we can’t stop radiation from many other sources.

If your bedroom and other rooms in the apartment are well-shielded, you won’t have to worry about radiation emitted by such sources. You won’t even have to turn off your WiFi router at night if your bedroom is shielded with EMF blocking paint. Before we share some examples of EMF shielding products, let’s discuss how they work.

What is EMF Shielding

How Do EMF Shielding Products Work

Michael Faraday invented the Faraday Cage in 1836, and it was a big success as it was a universally accepted EMF shield. The shielding products that are commonly used these days are based on the same principles. These products serve as a barrier between the radiation and a particular region (space) and attenuate it. The practice of shielding RF waves is also known as RF shielding.

The amount of reduction or attenuation depends upon several factors like the kind of material and its thickness. In some cases, it isn’t possible to completely block the radiation; however, we can reduce its level to a minimum. A cell phone is the most common example here.

If you want your smartphone to function properly, you wouldn’t want to block the radiation completely. But you can use a shielding product to protect your body against RF to avoid health problems. Some shielding products are designed to be kept in our pockets, and they act as a barrier between the body and the smartphone. If you use such products, your phone will function properly, and you won’t be at risk too.

What Materials Can Block EMF

Sheet metals, metal screens, and metal foam are commonly used to block EMF as they are very effective when it comes to attenuating radiation. Some common examples of sheet metals used for blocking EMF are copper, brass, steel, tin, and nickel. Among these materials, copper is the most reliable option as it is highly effective against electrical and magnetic waves.

These materials are commonly used in shielding products because of their effectiveness. Whenever you buy such a product, it would be better to keep an eye on the material used in its construction. Here is a small guide that will help you choose the right shielding products for your home.

How to Choose the Right EMF Shielding Products

When we talk about products that block radiation, there are several options to choose from, which can make things confusing. Before investing in any product, you should have a look at the sources of radiation near your home. Once you are clear about your requirements, things will be much simpler as you will know what you buy.

There are some basic products that you should invest in to make your home a happy and safe place to live in. You should start by painting the walls of your home with EMF shielding paint. EMF paints can block the radiation by up to 99%, which means your home will be safe even if there is a cell tower nearby.

Shielding your windows is also important as radiation can easily enter your home through them. Make sure to keep an eye on the window film material while making the purchase. Well, this is going to be enough to block RF from external sources. However, things don’t end here, as you will need to block radiation from devices at your home.

You should consider investing in a shielding canopy for your bed, and to add an extra layer of protection for your baby, you should buy a baby blanket that blocks EMF. Furthermore, you can buy a router cage to block harmful radiation emitted by WiFi routers. If you use all these shielding products, you are unlikely to face any health problems associated with EMF. If you have budget issues, you can buy them one by one in the order we listed them.

Frequently Asked Questions 

Does aluminum foil block radio waves?

Yes, aluminum foil can interfere with radio waves and block or attenuate them. You can use the thin sheet of metal as a shield to block RF.

Does copper block EMF?

In short, yes, copper can block EMF, and as a matter of fact, it is one of the most effective materials against radiation.

Do EMF blockers work?

EMF blockers are designed to attenuate radiation, which means they do work. However, when it comes to effectiveness, the type as well as the quality of material used in the construction of the product play a big role. Most manufacturers claim that their products block radiation by up to 99%, which is very impressive.

Does lead paint block WiFi?

In short, yes, lead paint can block WiFi by interfering with the signal. Multiple coating of such paint can make things even more impressive.

Do EMF stickers work? 

EMF stickers aren’t effective against cell phone radiation. They are small in size and cover only a small part of the device, which means they aren’t reliable. Modern devices like cell phones are designed in such a way that they boost their signals to compensate for interference, which means these stickers can increase the amount of radiation emitted.


In this article, we discussed what EMF shielding is and how it works. We hope you liked the article, and we were able to clear your doubts about EMF shielding. In today’s world, it’s very important to use shielding products as we are surrounded by smart devices.

Since we can’t stop using them, we should take the required steps to reduce their harmful effects. Using EMF protection and shielding products can improve your lifestyle as it will improve your health. These products will prove beneficial for you in the long run, and they will make your house safe than ever.
