Q&A 2012-2019 - For EHS By EHS

Q – How do you test the fabrics you sell?
A– We test most of the fabric we sell (other than YShield’s fabrics) in several cycles/ways:
1. We check the supplier datasheet to make sure his tests and characteristic are suitable for our needs.
2. We test the ability of the fabric to block RF, with a CORNET ED88TPLUS (or similar) fast RF Meter, against a home use DECT phone base station, when new and after several laundries, cycles to make sure the fabric can be washed in a washing machine with regular laundry soap.
3. We test the fabric’s ability to block RF radiation, over the frequencies between 300MHz and 5000MHz (this is the range that is tested. Fabrics might be able to screen/block also higher/lower frequencies, but currently we don’t have the equipment to show that) , in a special RF Testing Cage we have developed and built in the last few years.
Our RF Testing Cage

The meter used is the CORNET ED85EXS PLUS, and the source is an RF EXPLORER GENERATOR.
Since these tests are done with non-professional equipment we call it “RF DEMO TEST”

4. We then update the fabrics’ products page on this site with the following info:
– We state if the fabric is washable.
– We state the manufacturer’s RF attenuation test outcomes.
– We state our Demo test results summary for the fabric, including a picture from the test report with the attenuation graph over frequency.
– We Link to the full Demo test results report, so our customers can see the full results.
– When we make a product out of these fabrics, I use them myself to make sure they are working.
S190 - Summary of RF Demo Test report

Please see the following video with the explanation about our special built RF TEST CAGE – https://youtu.be/uqe8-PpA3yQ

* For professional and military use, we recommend to order one linear meter as a sample and then test it for your own need in your lab.
* For EHS people we recommend to first order a BC190 or BC240 and see how it feels, before buying many items or fabric.

Question – I wanted to make a very specific jacket, and I was wondering where I could go to get it made?
Answer – You can order the fabrics from us and make the jacket at your local tailor.Recommended Fabrics:(01/2019)

Q – I have rated my mobile phone with your fabric and I can still call it. Does that mean that your fabric is not working?

A. – No, it does not mean the fabric is not working but it may mean at least on the following:
1. You left some gap opened, and some “reception” (radiation from the cell tower) gets inside and allow the phone to receive calls.2. The level of reception in the place you did the experiment is high, the fabric can block about 98% of it. The raming 2% can still allow the phone to receive calls, then the phone transmits a much stronger signal to get to the nearest antenna. In some conditions, If done correctly and in a low reception area, when you wrap the phone, it should not get any calls and will not be able to connect the network. As shown in the video below (in Hebrew but you can see the effect) the phone loses the network (playing radio via application over the cellular network) when entered inside an RF Protective case made out of the S240 fabric. – https://youtu.be/8ZKZDmdK7-4 Press the “CC” for English subtitle

E.L. – Canada – 03/2018Q – We are being threatened with the rollout of a 5G technology cell towers/wi fi emitters. My question:
Do your meters measure this new frequency? Can your protection products can block 5G?
Thanks
E.L.

Updated answer 1/2020
5G is a nickname for faster, low latency, smaller size cells, wireless technologies.
The frequency range of 5G can go up to 300 GHz.
There are 2 main bands for 5G :
1. 600-6000MHz — to be used between antennas the devices. Passes via walls
2. 20GHz and above – This is usually used between antennas, buildings, and other stationary devices and infrastructure. This higher frequency is mostly blocked by everything.

Our EMF meters currently cover 100MHz-8GHz and might detect up to 10GHz.
Our RF Blocking fabrics (S132, S190, S200S, S240) are tested between 300MHz-5000MHz. They should be able to block also higher frequencies, but currently, we have no way to test it (please see below the test outcomes of S240 Fabric).
S240 RF Demo Test report

The Swiss Shield RF blocking fabrics are tested by the supplier (YSHIELD) up to 40GHz.
Please see their test outcome for one of their fabrics with 5G frequencies
STEEL-TWIN RF Report

Answer Mar2019 – Our meters measure Radio Frequency up to the frequency of 8GHz dependencies of the generation of that technology.

The mid-frequency of up to 5GHz will most likely be used for communication between infostructure to handheld or fixed devices, while the upper band between 20GHz and 300GHz will most likely be used for the fixed eye of site, point to point communication. Up to now, there is no technical standard for 5G. What we can find on the market is a bunch of products and technologies that are trying to achieve the “5G vision” or trying to make use of the 5G hype, but their frequency is well below 8GHz.

Answer Our meters measure Radio Frequency up to the frequency of 8GHz dependencies of the generation of that technology.
Around the world, we have tryouts and experiments of technologies that one day might be part of the 5G standard. For example, according to the 5G vision, in some cities in the USA and EU, mini or micro (small but still powerful) cellular cell antenna is being deployed in the cities. As far as I know, these antennas are smaller and operating under the concept of small cells as in 5G, some of them are even ‘Phased array” but most of them are still 3G(WCDMA) or 4G (LTE) based technology. Even if some of these new deployments are 5G, they most likely use the mid 5G frequency band of between 3.5 GHz-4.2 GHz.As far as I know, there are no products on the market right now, that is real 5G.
As far as I know, there is no real 5G around where I am, so I can’t say for sure the meter can measure t 5G technology. General saying, there should not be any problem using the CORNET ED88TPLUS or the ENV RD-10 to measure 5G devices and infrastructure if their emission is between 100MHz and 8000MHz.The same goes for our personal(hats and Clothes) and home protection, as long as the emission’s frequency is in between the frequency that the protection is able to block, it should work fine in 3G, 4G and 5G.

Q – I want to know how the cornet lets you know the battery is low.I had it on just now, and it went ballistic on the RF setting, then the indicator light on the right, that will show green, yellow or red, got very dim, and it seemed to shut down,
Before it shut down, the readings were very high, the alarm was going off, and it did turn back on again.
I changed the battery in case it was a ‘low battery’.When I turned it back on, the alarm didn’t go off, and it seemed to operate normally.
How exactly does it tell you it has a low battery?
Thanks in advance.

A – “BAT” on the upper left corner of the LCD
The meters show “BAT” on the upper left corner of the LCD, below the “ED88” text when the battery gets too low..After that, if the meter is still used without changing the battery, the RF reading might go to 1827 and the alarm might sound on. After shutting the meter off for a while, it is possible that the battery will recover a bit, and that you will be able to work with the meter for a couple of minutes. But them it will go crazy again. This is very similar to what you describe. Please see the picture below. Please change the battery, we recommend using rechargeable.
I hope this info helps
Thanks and best regards

Q – Why can’t I use cell phones and wireless devices while wearing RF Protection clothes?A – You should not wear RF protection clothes while using cell phones or wireless devices for several reasons:
1. RF Protection Clothing is for EHS people.
EHS people should not use cell-phones or wireless devices if they want to get better.
EHS people should use wired corded phones and computers.
2. Wearing RF Protection Clothing is a last resort.
Before buying and wearing RF Protection Clothing is recommended to stop using RF emitting devices.
3. The RF Protection Clothing will block some of the RF (usually most of it).
If the user uses a wireless device while wearing it some of the RF will manage to get to the user’s body.
4. If the user is an EHS he will feel this radiation.
The hats are designed to block RF radiation from the environment, not from devices that are very close to the body.
While using cellphone next to the head, some of the RF and all of the ELF magnetic field will pass the RF Protection hat and will cause EHS people a headache.
5. We don’t want cell phone users or wireless devices users will buy our products just so they could silence their conscience. There are a lot of other products out there, that are meant for that.

Q – in the fabrics’ RF reduction info, some sites show the reduction effect in dB unit, some in %, your site shows both. What is the difference between dB and %, and what is a good number?
A – dB is the bumping effect of in logarithmic nature.
It is usually used in professional RF protection since the difference between -0dB and -100 dB is very big.
The following table is a conversion between dB and %

RF-Reduction dB/%

Well, I think that measuring in dB is highly misused when it comes to every day RF protection, especially in clothes and hats. The use of dB units comes from the military and professional world of RF protection, where sometimes you need to go down -90db or even lower.
In case that you have only one penetration point (happen in the military or professional world but not so much in the real world) then a protection material with -20 dB will be better than one with -15db and much better than -10db.
But in everyday world, where there are many penetration points and the installation is usually not perfect, if you pay more for a -50db (~99.999%), or even -35db(~99.97%) compared to a -25db(~99.7%) or -20db (that ~99%), I think that at least in some cases it is a waste of money.

For example, if you protect a car, and you don’t protect the front windshield (since in most countries it is illegal and because it can distort the road view, especially at night) then more RF will come from the front windshield than the difference between RDF62 and RDF72, and the price for the RDF72 will be double.

A second example, if you need curtains, and you install the curtains in a way that there are not glued to the wall or window (there is some air between them), then more RF will come in from this gap than the difference between -25dB to a -35db fabric.

A third example, if you are looking to make a hat, more RF will come into the head from the places you can’t cover, than the difference between a -20db to a -30db fabric.

Q – Hi, Amir, I see that you are dealing with some protective fabric… I myself don’t like shielding as I feel the other kind of discomfort in Faraday cages and know others who have a similar experiences… I would like to hear what you say regarding that “other kind of discomfort”… By the way, mice in experiments also avoid screened rooms.D.C 31/03/2017

A – WOW Great Question! thank you for that!
Most of our costumers report that hats, clothes and house protection helps then a lot. Some people feel discomfort because of several different reasons. These are the reasons I come across so far:
1. Some are sensitive to the fabric – I think that other then in a hat, the fabric should not be on the skin (not as an undershirt or underwear). I recommend my costumer to wear the Shirt, Jacket , pants and ponchos over normal clothes and underwear/undershirts.
In addition, I recommend to my costumers first to test the fabric, by getting the cheapest possible product and see how it goes. I sell RF protection lining/inserts for $15, this product can be a great test product.
2. Some people use personal protection while still using RF emitting devices – I recommend/ask not to use hats and clothes while using wireless devices. The first thing you do as an EHS person is to stop using cellphones and wireless devices, not buying protection.
3. Some use RF protection before reducing exposure first – I explain that first, you need to stop using the cellphone and wireless devices. then use an EMF meter to find all sources inside the house, keep safety distance from ELF sources, remove all wireless sources, find penetration points of RF to your house and use the RIGHT (!!!) RF protection to block it (lots of people don’t understand which protection to use in which situation and how to use it. These people will most likely make mistakes, like protecting the walls before the windows, like using the RF blocking paint inside the house – might cause reflections, or using RF protection at all before removing RF sources from the house. Another mistake is to connect RF protection to the electrical ground.
4. Some people use the protection with no understanding of RF – I explain that the personal protection should be used only to bring relief when exposure to environmental RF radiation such as cellular towers and WIFI routers which are installed above the user, and not for RF sources below the user (the protection is usually opened from below, so the RF that comes from below will enter it). I try to explain all this in the limitation chapter on the Hats and Cloths pages (http://www.4ehsbyehs.com/protection-clothes/rf-protection-hat#TOC-Limitations, http://www.4ehsbyehs.com/protection-clothes#TOC-Limitations) and in my info site http://www.norad4u.com/emr-protection
5. The Blocking effect is not 100%. Some RF will still be coming in from the holes and opening in the design and some people will feel that. So even if the personal protection helps, it will not be 100%. I recommend to try and measure the relief it brings you. For example, without a hat, I feel pain (headache) in my living room after 5 minutes. With it, only after 5 hours or more. I can still feel pain after more than 5 hours, but that does not mean the hat is not working.
6. An addition thing might be that in most fabrics (not the one I am using for my hats and clothes) the RF blocking effect will be reduced after several washing. So people will feel worse and worse as they continue to wear the hat or cloths.

7. One more thing, the body creates it own EMF field. So some people will not feel good inside the RF protection clothes if the blocking effect is too great. I feet this too, and when it happens I just open the RF Protection Jacket a little bit. I know that when going to the city with the Jacket I will feel some discomfort after 20 minutes, but without it I will feel worse sooner.
Remember:: Protection, both personal and house protection is the last step.
In the picture – me and my models wearing RF Protection Clothes

Q –
A – The hat is for Electromagnetic hypersensitive (EHS) people (Electromagnetic Sensitive people included) that feel pain when around RF radiation sources.People who do not feel the radiation will not know that the hat is helping them and might use it incorrectly (like when using a cellphone while wearing a hat).People who are not EHS/ES, will benefit more from exposure reduction, from using an EMF meter, from house protection than from personal protection.
Please see – Who can benefit from our products

Q – 1. Why are you using the SHIELDON 240 fabric in all your hats and clothes, while there are other RF blocking fabrics that can block better than what the SHIELDON 240 fabric can?
A – The reason is that the SHIELDON 240 is the best fabric we have. It has a good blocking ability, it is very durable and will last for yearsThe SHIELDON 240 is the most durable fabric we know of.
You can wash it in a washing machine and it will not suffer any reduction in it’s ability to block Radio Frequency radiation.
It will last for many years and will require no maintenance. When you buy expensive RF protection clothes, using the cloths for many years is a big plus!
The SHIELDON 240 fabric has a blocking effect of more than 99% (higher than -20 dB tested for Frequencies of 10MHz to 3 GHz) which is enough for making cloths and hats (more RF will come in from the opening of the hat or cloth, than trough the fabric itself). Other fabrics may have a higher blocking effect, but they are not as durable and after several times you wash them, the blocking effect will go down, sometimes for more than 50%, sometimes even farther down. In

Q – Hello I just order 3 of your electric magnetic radiation blocking fabrics (S240 & S238)
Thank you so much, I looked all over the internet for your product needed for electric emf’s from using electric appliances I am going to make an apron to protect my upper and lower abdominal areas. Our house is full of emf and wiring issues. But the oven and refrigerator is killing me every time I cook on that terrible electric stove and get very high readings from my meters and also feel the sickness,
burning, pain and urination frequency. I am so thankful to you and your website.
I would purchase any cloths you have as well if they are mostly for electric emf’s. We do live near clusters of cell towers too, but the RF’s are very low. Please keep me as a lifetime customer.
Sincerely
J from USA
A – Hello J
Thanks for the warm words about my site.Thanks for ordering from my site.
The Fabrics you ordered and most of our products are made to block RF-Radio Frequency Radiation. Most Electric appliances emit ELF-Extreme Low-Frequency EMF radiation, which the fabrics will not block or reduce.
Some Electric appliances emit also RF radiation, but the right way to deal with this emission is to disable the wireless function or changing the appliance to a different model that does not have wireless capabilities and does not emit RF radiation. We produce RF Protection Clothes and sell RF blocking fabrics but their main goal is to protect EHS-Electromagnetic Hyper Sensitive people (as I suspect you are) from RF that is not coming from their house, but from the outside, like for example cell towers.
The first thing you need to do is to disable or remove any wireless device from your house. In addition please try and see if you have a “smart meter” installed against your wall, these emit a high burst of RF radiation. It will also help me to know which EMF meter you are using to measure the EMF in your house.

Q – Hello,
I have a question regarding the paint. I live in a `two under one roof´ house, is it possible to paint only the wall to my neighbor with the blocking paint to shield my family from the radiation? The guy has WiFi, a repeater and a dect phone in his house…

Best regards,
B. 17/03/2016
A – Hello B.It is possible to use RF protection on the wall between you and the neighbor in order to block most of the RF coming from his home, but it is important to pay attention to the following:1. If you use protection, you first need to make sure that you don’t have RF emitting devices in your house.2. Use an RF meter to make sure where from the RF is coming (some of it can also come from other places, directions or devices).3. Find out what the ceiling is made of and if some of the RF generated by your neighbors is penetrating through it.4. The right type of RF protection should be selected. For in house I prefer using the RF Blocking wallpaper – http://www.4ehsbyehs.com/rf-protection/rf-blocking-wall-paperPlease also see http://www.norad4u.com/emr-protection/rf-protectionI hope this info helps.amirb

Q – Dear Friends,
I suffer from WIFI signals from my apartment neighbors as well as pain if very close to cell phones.
I used a cell phone extensively for 20 years but cannot put one to my ear now without getting pain.I was wondering if one of your hats RF (EMF) Protection Legionnaire Hat would stop the signals to my ears while sitting on my couch watching TV. As well my ears get red and are hot when these signals are coming into our apartment.
Thanks for answering me. I would like to order right away if you think it might help you.

AnswerHello and thanks for contacting us at www.4EHSByEHS.comEHS – It seems that you are an EHS person, like myself ( please see my info site – http://www.norad4u.com/ehs ).Hats – Yes, Our line of RF Protection Hats should help you feel better when the RF radiation is coming from your neighbors, from cell towers, from WIFI routers and RF sources installed above you. I wear the RF protection hats all day long, including in the house and it helps me a lot.

Question – ” flying at 35,000 feet,” – commercial air plan or private?

What more can you do?
In addition, I recommend to get an EMF meter and start searching for RF/ELF sources inside the house, and penetration points where from RF and ELF are getting into your house.RF sources that are found should be removed and changed to wired equipment.ELF sources that are found should be kept at a safe distance from you, and unplugged from the electric socket when not in use.RF/ELF penetration points should be blocked and protected.

Q – How do I measure my head size
A – You should take a measuring tape and put it around your head, a bit above the ears and eyes. This head size is 53.5cm

Q – Hi Amir,
How do I differentiate between the shiny and non-shiny side of the screen?J – Canada29/11/2015
A – Hello
From past experience, it is hard to notice a difference but the good news is that both ways the film works very nice.
If you want to do it 100% right, then the outside side of the film(the side that should be facing the screen) is the side that is covered by a transparent thin-film layer. Try to take the 2 layers just a little bit apart in order to find the side which should be facing the screen. Once you find the outside side, make it face the screen. I hope this info helps. All the best

Q – I notice it says that the environment must be free of wireless devices. Once a week I enable my wireless to update my phone. Is this going to be compatible with this LCD/LED screen protection film? What is the purpose of the need to be free of wireless or wifi if other than to decrease rf?

A – Hello.
The LCD/LED Screen protection film is for Electromagnetic Hyper Sensitive people.
The Film is meant to reduce exposure to the Mid Frequency Electromagnetic Radiation emitted from LCD/LED PC screens. This Mid-Frequency EMR makes most EHS people feel itching eyes and heat sensation on the face when working in front of a wired PC screen.EHS people will feel a lot worse if a wireless device will be active near them, so there is no real reason to try and protect from the screen’s EMI fields while a wireless device is active around EHS people. In general EHS people should not use wireless devices. If you are an EHS person, I recommend not to use any wireless devices and relay only on wired devices.
For none EHS people, please note that wireless laptop, WIFI routers, DECT phones, cellphones, and others RF devices emit Radio Frequency radiation that is by far more powerful than the radiation emitted from the screen itself, so there is no use of getting screen protection if you are still using wireless devices. Most people that have wireless equipment and put on the screen protection will not feel a big difference if any.
All the best

Q – I wanted to ask that when I sometimes play a video game I suffer from irritation fatigue and agitation does that screen helps if I play and put it on my tv ( use ps4 and xbox 360 and I have a cellphone that’s the only thing that is wireless..)?

A – Both the PS4 and the Xbox emit constant RF radiation for the WIFI communication and for the wireless remote control.
Please see – https://www.youtube.com/watch?v=4X7-XSdjU1AIt is most likely that that the iPhone you are using also emit almost constant RF radiation when the Data connection, WIFI, and Bluetooth are turned ON.https://www.youtube.com/watch?v=bLBliuGGu-4
My guess is that the headaches you experience while playing is caused by the above RF radiation. In order to minimize the exposure, I guess to use the PS4 when the remote controls are connected via USB to the PS4 (never tried it on PS4, on PS3 it worked) and turn off the WIFI connection. Regarding the Xbox, I don’t know how to operate it with minimized radiation emission. In addition, turn of the WIFI, 3G/4G data, and Bluetooth on the iPhone or just put it on “flight mode”.If the headaches are caused by the RF radiation, you should feel better when all the wireless is off. If you still feel something, then and only then, the LCD screen protection might help (http://www.4ehsbyehs.com/rf-protection/LED-LCD-screen-protection-film)The EMF emission from the screen is usually just a fraction of what you get from all the above devices. You can buy an EMF meter and see the radiation your self – http://www.4ehsbyehs.com/emr-meters/cornet-ed78sI hope this info helps.
Constant RF from XBox

A – You should not wear RF protection clothes while using cellphones or wireless devices for several reasons:
1. RF Protection Clothing is for EHS people. EHS people should not use cellphones or wireless devices.
2. Wearing RF Protection Clothing is a last resort. Before buying and wearing RF Protection Clothing it is recommended to stop using RF emitting devices. EHS people that don’t stop using wireless devices or cellphone can’t expect their condition to improve.
3. The RF Protection Clothing will block some of the RF (usually most of it but not all). If the user uses a wireless device while wearing it more of the RF will manage to get to the user’s. If the user is an EHS he will feel this radiation.
4. We don’t want that cell phone user or wireless devices users will buy our products just so they could silence their conscience. T
5. here are a lot of other products out there, that are meant for that
.Picture – RF Protection Clothes

Q – I would like to purchase protective clothing, because at work in a room with a very bad reception almost 50 people use smartphones and tablets. My home is more or less safe and I’m avoiding EMF as much as I can.
A – I use the RF protective clothing mainly for going in the street and driving my car. I try to avoid being next to people who use cellphones and other wireless equipment. When I worked in a high-tech environment (where people love their cellphones and wireless gadgets and where WIFI and cellphone antennas were hidden in the ceiling) I used to wear my RF Protecting Hat all the time, in some cases I also wore an RF Protection Jacket. If you are new to RF protective clothing I suggest that you start with an RF protecting hat. After wearing the hat for a while, you can try also the RF Protection Jacket and RF Protection Pants.

Q – I suffer from symptoms (fatigue) when close to a router or laptops with WiFi. I might soon have to spend some hours in a classroom with Wi-Fi – and possibly students that connect wirelessly to the router. I wonder if this shirt would reduce the radiation on me in such a classroom…?
A – The RF protection clothes will help, to some extent, depending on the type of fabric, on the location of the RF source and on the level and type of the person sensitivities. If there is only one WIFI router and if it is installed on the ceiling or upper part of the wall, then an RF Protection Hat and an RF Protection Jacket or an RF Protection Shirt will help. If the class is full of cellphones, tablets and wireless laptops, then it is harder to say. The idea should be to avoid such environments.

Picture – RF Protection Clothes and hats for EHS people

Q – I live above neighbors who have their WIFI router on permanently. I worry for the health of my children. I know where their router is positioned (under where our couch is positioned in the living room) and was wondering how I could go about blocking the WIFI radiation.
Do you sell RF blocking carpets? Another solution may be to line a normal carpet with RF blocking cloth.
Do you have any suggestions?
Kind regards,

A.- Hello and thanks for contacting us.
I recommend buying an EMF meter and measuring the RF levels in the room before installing protection on the floor.
If the RF penetration is small and local you can use a small piece of RF Blocking Carpet or fabric and put a normal carpet on top. If the RF penetration is big, from all around the floor, you can line the floor with RF Blocking Fabric, ground it and
cover it with wood floor or carpets.

Q– Hi, I have huge problems with neighbors/flatmates, I am not sure which however I have symptoms which stipulate they are using rf technology near me or against me which is disturbing, I need the most cost-effective or linen curtains and clothing if possible please, all and any information will be of help. Thank you.

A– Hello and thanks for contacting us.
My name is Amir and I am an Electromagnetic Hyper Sensitive (EHS) person, which means that I feel bad when being around RF/ELF EMF radiation which is emitted from cellphones, mast, wireless devices, power lines, and electric devices. If you feel bad hat home, you might be an EHS person and I recommend to measure the RF and ELF levels and try to track down the sources and penetration points to your house. Then we can choose the best protection for the case. This should be done alongside with minimizing the use of any Radio Frequency emitting devices – http://www.norad4u.com/emr-reduction
