Update: Unfortunately, I am seeing a significant reduction in attenuation. This is despite following the strict guidance for laundering the fabric. My guess is that the fabric is simply too thin and delicate to handle the stress created across the seams, and tiny holes which leak the EMFs are being created. The canopies were a significant financial investment and I am disappointed. I suspect we will be moving forward with shielding paint in our bedrooms in lieu of fabric canopies.


Among the many environmental triggers for our health issues, EMFs are a serious threat. Since experiencing and witnessing the affects from our home in 2017, I have read and watched nearly everything I can find on the subject. I have also amassed a respectable collection of meters, which measure RF, EMI (dirty electricity), electric and magnetic fields. This Blocsilver fabric shields radiation from the RF (wireless) signals, and it's the least expensive I have been able to find for the level of attenuation. I have used this fabric to create canopies for our California king sized bed, my 2 kids' twin beds, and our dogs' sleeping crate. The pink and blue tents in the photos are items I found on Amazon which make a convenient 'skeleton' for the kids' EMF fabric canopies. I built a PVC pipe frame for our master bed, and used rubber tipped clips (also from Amazon), to secure the fabric. I am not skilled in the sewing department, so I had to find an alterations store, who charges me ~$80/canopy to stitch the pieces together according to my instructions.

The fabric comes in pieces approximately 10'x5' in size, so it will take almost 5 pieces to make a ~15'x~15' canopy large enough for a twin sized mattress on the floor, draped over the tents shown in the pictures. If you use a bedframe raised off the ground, you will need more fabric to reach the floor. Since the fabric contains metal, it will need to be grounded and you can find grounding cables with clips on the lessemf website. Nearby power outlets are the most convenient grounding source, but that will potentially conduct EMI (dirty electricity) from the home's wiring into the fabric. To mitigate the issue, we turn off the circuit breakers for each of the bedrooms at night and run extension cords from other outlets to power critical things like sound machines, air filters, and my husband's CPAP machine in the rooms overnight. Eventually I hope to upgrade to a remote-controlled circuit breaker from the emfsleepsafe website, just to make our lives a bit easier.

We do not use WiFi in our home, but we do live within close proximity of several visible cell towers and an airport. The kids’ rooms are closest to the cell towers. One layer of the Blocsilver fabric is not enough to reduce the RF levels to the ‘green’ zone on my Safe & Sound Pro RF meter in their beds. I have added a 2nd layer of Blocsilver fabric so their beds now measure within the recommend safe levels for sleeping by the Building Biology Institute. RF signals travel through walls and structures, so if your bed is not on a ground floor, you will also need shielding fabric under the bed. Since it doesn’t need to be sheer for air flow, I recommend the cheaper grounding sheets sold on the lessemf website. They come in different sizes, and I have found that I need to purchase several and overlap them to get full ground coverage.

I have had the older canopies for 1.5 years now, and I will update this review if/as they begin to lose their shielding capacity. Eventually, I would like to use shielding paint on the walls and film on the windows, so we are protected 24/7 and don’t have to bother with the bed canopies and grounding anymore.

Yes, all of this is a pain. And yes, it's expensive. But the disturbing relationship between the FDA, FCC, and telecommunications industry, coupled with the scientific research demonstrating the danger has lead me to believe this will be the next tobacco scandal. Although I suspect it will be decades before anyone starts to take it seriously. In the meantime, I have no intention of making myself and my family this nation's guinea pigs. And I really couldn't care less who thinks I'm crazy. ;-)

1.0 out of 5 stars Blocks EMF and looks nice! Until it does not!!! Tarnished after 4+ months
Reviewed in the United States 🇺🇸 on June 6, 2021
Update 6 months later:
I am so disappointed at this product. Is totally tarnished now. It started to change colors around 2 months, spots here and there. 4 Months, tarnished almost everywhere. 6 months -with the exception of 6” strip across the bottom, the whole thing is tarnished/corroded really bad. Looks awful!
The bottom is not as exposed to air as the rest of the piece. This part is on the floor. Since I was using this as “screen door”. I can only imagine how bad it would look as a bed canopy. This is not around water, so it must be the air that makes it go bad.

It is a total waste of $180.

Do not buy, unless you want to be disappointed 4 months later.

I have tested many materials, some work, some do not. I am please to say, this one was a keeper!
I had to return the first item because it had some stains. The replacement was in great condition. I am using it to block the EMF from my neighbors. I set it up at the top of my staircase, like a screen door to come into the living area. It is on the expensive side, but the other material that is transparent is not recommended to be touching your skin. And i was going to opening and closing this "door" so i need something that i can continuously touch. This is supposed to be for bed canopy. My bed is shielded on the walls, no need for a canopy. Thanks!
