As we continue with our partners to develop our own performance brand emf-protection fabrics, we are particularly excited by our 3rd generation of the already popular Blocsilver.

Blocsilver 3 has an increased silver (the expensive bit that reflects RF) content raising its emf protection shielding performance across the in-use RF frequencies of today to between 51.4 dB (900 MHz) and 39.7 dB (10Ghz)

I don’t believe there is a more economic and effective breathable and see through emf protection fabric available on the market today.

Blocsilver emf protection fabric will mitigate all normal range EMF from Cell towers, (phone masts) Wi-Fi, smart meters and cordless phones.  It will effectively shield  from 5G

7 reviews for EMF Protection Fabric- Bloc Silver – 1 Unit = 5ft x 4.92ft

  1. X is Tenshell

    My wife, who started getting serious breathing problems and bad headaches, believed she’d narrowed the cause down to radio wave transmissions from heavy use of her laptop and wireless router. I was extremely dubious of this being the likely reason, but I can only say that this fabric has helped tremendously. She has had no attack since using this product and, together with cutting down on her laptop use, appears to have her health back. I don’t believe there’s any placebo effect going on. (I am currently changing all wifi connections back to cable – which isn’t easy – that should also reduce the strength of wireless radiation in our home). When we were researching this phenomena, we were amazed at two things; how many people were getting ill and how little is said about these serious side effects. I can see this becoming a major scandal in the future, similar to our now enlightened view of smoking. We’ll probably look back at footage of people wearing VR headsets and cringe . . .

  2. Amazon Customer

    We live next to a GSM antenna. The EMF radiation level on my acoustimeter dropped significantly after shielding on of my rooms with this fabric. It’s kind of expensive but I think health is more important.

  3. Amazon Customer

    This is taken from an email I sent to the seller

    I got the fabric a little bit ago (the package took some damage in transit to the USA, but the material came through unscathed). It took me a while to set it up in a trial configuration, since it’ll be on the floor of my place under the couch and coffee table.

    If you remember, I have one of the 3 axis electro-smog detectors. Previously where I like to sit had regular bursts of ~25mW/m^2 or more, I think from my downstairs neighbor’s router. With this fabric in place it’s dropped to 2 or 3 mW… at the couch base. And that’s in a non-enclosed space! Just 6 inches away I’m still seeing the bursts.

    This fabric is fantastic.


    A little extra for this review, you DEFINITELY want a grounding cable. I have a kinda-weak grounding setup right now, and the way the fabric is laid out my heels can touch it, I have an all metal mac book laptop which actually makes a pretty excellent ground. I can feel a difference when I go to type on the laptop if my heels are touching the fabric (because the ground switches to me) so get a grounding cable and hook it up!

    Covers bed between sheet and blanket – soon ordering a second one!

  5. Michael

    It reduces RF and EMF. I hand washed in cold water, no detergent or soap, when it first arrived. This removed a slight odor and did not impact RF or EMF blocking ability. It works and is a good value. Now I proved it works, I’m looking at a bed canopy.

  6. Chidori

    This is an awesome product. I tested with my acousticom 2 meter by wrapping it with the sheet and it completely silence it. So I install it on my windows, by layering my drapes. I have cell tower radiation coming in from the windows, and this did the job. On acousticom, it shows a reduction from .10 to .02 V/m.
    Also, the price is great for this product. Note, that this product will block out your window.

  7. Fernando

    It works very well.
