Product details
A Box-Shaped Canopy Suspended Over Your Bed
The BlocSilver® Suspended EMF Bed Canopy wraps your bed in a box-shaped enclosure of BlocSilver® shielding fabric, reducing the RF signals from WiFi routers, cell towers, smart meters and 5G that reach you while you sleep. It is made from the same fabric as our four-poster canopies, but with a different design: instead of a freestanding frame, this canopy hangs from the ceiling above your bed. Compare it with the rest of our EMF bed canopies.
Generous 6.5 ft Height
The canopy stands 6.5 feet tall across its whole width and length, with a box shape that leaves plenty of room around the perimeter of the mattress. That gives you a spacious, comfortable sleeping space rather than a tight tent over the bed.
Shielding Performance
BlocSilver® provides 36 dB of shielding at 40 GHz, which covers the high-frequency millimeter wave range used by 5G. At lower frequencies, including the WiFi and cell phone bands, attenuation is higher, at around 45 to 50 dB. Decibels are a logarithmic scale: every 10 dB is a tenfold reduction in signal power, so 36 dB means more than 99.9% of the signal power at that frequency is blocked.
| Frequency | Attenuation |
|---|---|
| 30 MHz | ~50 dB |
| 100 MHz | ~49 dB |
| 300 MHz | ~51 dB |
| 915 MHz | ~50 dB |
| 1.5 GHz | ~48 dB |
| 2.45 GHz | ~46 dB |
| 5 GHz | ~45 dB |
| 8 GHz | ~40 dB |
| 10 GHz | ~38 dB |
| 20 GHz | ~35 dB |
| 30 GHz | ~35 dB |
| 40 GHz | 36 dB |
30 MHz to 1.5 GHz measured per ASTM D4935-18 / GB/T 30142-2013. 2.45 GHz to 40 GHz reflect internal measurements.
Lightweight, Breathable Fabric
BlocSilver® is lightweight, breathable and durable, so you get shielding without the stuffy feeling of a sealed enclosure.
Installation: Hung From the Ceiling
This canopy attaches to your ceiling using eight hooks. The hooks are fixed into the ceiling, so installation is a DIY job and is not ideal for renters or anyone who does not want to make holes in their ceiling. If that rules it out, our Four Poster canopy comes with a freestanding frame and needs no hooks, screws or fixings into your floor or ceiling. Both use the same BlocSilver® fabric.
Choosing Your Size
The canopy is available in Crib, Twin, Twin XL, Full, Full XL, Queen, California King and King sizes. Choose the size that matches your mattress.
Grounding
Like our framed canopies, this canopy needs to be grounded. An EMF Canopy Grounding Kit is included free of charge.
Do You Need a Bed Mat?
It depends on which floor you sleep on. BlocSilver® is conductive, so on the ground floor the canopy on its own creates a Faraday cage around your bed. If you sleep above ground level, signals can also reach you from below, so add an EMF/RF bed mat under your mattress to complete the enclosure.
Care and Washing
BlocSilver® can last up to 40 washes while still maintaining its shielding properties, if it is washed according to these instructions. Washing will eventually degrade any fabric containing silver fibers and reduce its shielding performance, so wash only when you need to. The fabric is encased in an antioxidant coating and can be spot cleaned or wiped down with a damp rag.
- Use Texcare or a pH neutral detergent to help protect the silver.
- Gently hand wash with cooled boiled water or mineral water, especially in high chlorine areas. You can also machine wash on a gentle cycle with cool water.
- Hang dry indoors only, and keep the fabric away from direct sunlight to prevent silver oxidation.
- Avoid use in high-salt or sulfide air conditions.
- Do not use oils, bleach or any chlorine-based detergent, and do not iron or dry-clean.
Test your tap water first. Poor water quality damages the silver in the fabric. Sulfur, high fluoride and low pH react strongly with silver and can destroy conductivity and shielding performance. Before washing, test your water on a small fabric swatch:
- Soak a small swatch in tap water for 1 hour.
- Look for a color change in the water or swatch, especially blackening.
- Air-dry the swatch and check its conductivity by touching an ohm meter to two points on the fabric.
- If the color changes or conductivity is lost, do not use tap water to wash or rinse the fabric. Use distilled, deionized or reverse osmosis water instead.

About Silver Fabric and Discoloration
Silver products discolor over time, which is normal, and can be stained from the factory. If you cannot accept discoloration, please consider a Swiss Shield® canopy instead.
Designed and Made in the UK
This canopy is designed and made in the UK, from high-quality BlocSilver® shielding fabric.
Warranty
The BlocSilver® fabric in this canopy carries a two-year warranty against manufacturing defects.

It uses the same BlocSilver® fabric, but the design is different. This is a box-shaped canopy that hangs from the ceiling using eight hooks, while the Four Poster canopies come with a freestanding frame and need no fixings into your ceiling.
It hangs from eight hooks fixed into the ceiling above your bed.
It is a bit of a DIY job. You need to fix eight hooks into the ceiling and hang the canopy from them, so it suits someone comfortable with basic DIY. If you would rather avoid this, our Four Poster canopy comes with a freestanding frame that most people assemble in about 15 minutes, with no hooks or screws.
It is not ideal. The hooks are fixed into the ceiling, which means making holes. If you rent, our Four Poster canopy is a better fit, because its freestanding frame needs no fixings into your floor or ceiling.
Yes. Like our framed canopies, this canopy needs to be grounded. An EMF Canopy Grounding Kit is included free of charge.
Yes, with care. BlocSilver® can last up to 40 washes while maintaining its shielding if you follow the care instructions, but washing will gradually reduce shielding performance. Hand wash gently with a pH neutral detergent and cooled boiled or mineral water, or machine wash on a gentle cycle in cool water, and hang dry indoors away from direct sunlight. Test your tap water on a fabric swatch first, because some tap water can damage the silver. Never use bleach, chlorine-based detergent or oils, and do not iron or dry-clean. See the full instructions in the description, or watch our washability test video.
The canopy is 6.5 feet tall across its whole width and length, leaving plenty of room around the mattress.
36 dB at 40 GHz, and around 45 to 50 dB at common WiFi and cell frequencies. Every 10 dB is a tenfold reduction in signal power, so these figures represent a very large reduction in the RF reaching your bed. See the attenuation table in the description for the full range.
Yes. Attenuation is around 46 dB at 2.45 GHz and 45 dB at 5 GHz (the WiFi bands), around 50 dB at 915 MHz (a common cell and smart meter band), and 35 to 36 dB across the 20 to 40 GHz millimeter wave range used by high-band 5G.
Only if you sleep above ground level. On the ground floor, the canopy on its own creates a Faraday cage around your bed. If you sleep upstairs or anywhere above ground level, add an EMF/RF bed mat under your mattress to protect from below.
Crib, Twin, Twin XL, Full, Full XL, Queen, California King and King. Choose the size that matches your mattress.
Yes. BlocSilver® is lightweight and breathable, designed to create comfortable sleeping conditions.
Use an RF meter. Take a reading at bed height outside the canopy, then take a reading at the same spot inside with the canopy fully closed. The difference shows how much signal the canopy is blocking.
Yes, silver products discolor over time, which is normal, and can be stained from the factory. If you cannot accept discoloration, we recommend a Swiss Shield® canopy.
If you are not completely satisfied, just let us know. As long as the canopy is undamaged, we will happily accept a return. See our returns policy for details.
Yes. The BlocSilver® fabric has a two-year warranty against manufacturing defects.
