Pros
- Provides over 60dB shielding for RF radiation, with 99.6% effectiveness at 5.6GHz.
- Constructed from copper material with breathable radiation protection fabric.
- Measures 13.7 x 15.7 inches, fitting many standard routers.
- Allows for adjustable signal leakage by partially placing it over antennas.
- Offers a 30-day money-back refund policy if not satisfied.
- Claims to block yellow dust and fine dust from the router.
Cons
- Effectively blocking RF radiation will inherently degrade or eliminate Wi-Fi signal, rendering the router non-functional for wireless connectivity.
- The material is not advised for washing.
- The product's core premise of 'blocking harmful EMF' while maintaining Wi-Fi functionality is scientifically contradictory.
- No specific user feedback confirms improved sleep or head protection from electromagnetic waves, as claimed.
- The product's value proposition is questioned by many in tech communities, often labeled as 'snake oil'.
Dimension Scores
The cover's stated purpose of blocking RF radiation by over 60dB will directly and severely impede a router's wireless throughput and range.
By blocking the Wi-Fi signal, the cover makes the router unreliable for its core function of providing wireless connectivity.
Setup involves simply tucking the 13.7 x 15.7-inch fabric around the router, and management allows for partial placement to adjust signal leakage.
While it claims to block '5G' and 'electromagnetic waves,' this is a physical barrier against radiation, not a network security feature like encryption or firewall capabilities.
Best For
- Individuals prioritizing EMF/RF radiation reduction above wireless network functionality.
- Users who primarily use wired connections for their router and want to reduce ambient RF.
- Those seeking a physical barrier for dust protection for their router.
- People who believe in the health benefits of EMF shielding and are willing to compromise Wi-Fi signal.
Not Recommended For
- Anyone needing a functional Wi-Fi signal from their router.
- Users expecting to maintain full wireless throughput and range while using the cover.
- Individuals looking for scientifically proven health benefits from EMF shielding without signal degradation.
Watch Out For
- Applying the cover for maximum radiation reduction will likely result in a complete loss of Wi-Fi signal, making the router unusable for wireless devices.
- Users report that products designed to block EMF from routers act as Faraday cages, which by definition block wireless signals.
- The claim of blocking 99% of radiation while still allowing Wi-Fi to function is contradictory to how radio frequencies work.
- Some similar products have been criticized for cheap construction, like being repurposed paper holders.

What Buyers Say
Many users in tech discussions express skepticism about the product's claims, noting that any effective RF blocking will inevitably disable Wi-Fi functionality. The concept of a 'Faraday cage' for a router is frequently mentioned, with the understanding that such a device would prevent wireless signals from working. While the product claims to offer over 60dB shielding and 99.6% effectiveness at 5.6GHz, the practical implication for a Wi-Fi router is a significant loss of signal. Some see these types of products as 'snake oil' or a placebo, suggesting that if it makes people feel better, that's the only benefit.
“I bought this thing because I heard about 5G radiation, but now my Wi-Fi barely works, like, what's the point if I can't even stream Netflix? I guess it's good if you just want to look at your router, not use it.”
Common Praise
- The 13.7 x 15.7-inch size fits many standard routers.
- The copper material with breathable fabric feels like a quality construction.
- The ability to adjust placement for more or less signal leakage is a thoughtful design.
- The 30-day money-back guarantee provides a safety net for trying it out.
- It physically covers the router, potentially blocking dust.
Common Complaints
- When fully applied, the cover severely degrades or completely blocks the Wi-Fi signal, making the router useless for wireless devices.
- The fundamental premise of blocking EMF without affecting Wi-Fi is seen as scientifically unsound by many users.
- Some users perceive these types of products as a marketing gimmick rather than a functional solution.
- The material is not suitable for washing, limiting maintenance options.
- No concrete evidence from user reviews confirms claims of improved sleep or head protection from electromagnetic waves.
Ownership Tips
- After a few days, I realized my phone kept dropping Wi-Fi, and I had to keep adjusting the cover to get any signal.
- The 'breathable' fabric didn't seem to make a difference in router temperature, but my Wi-Fi signal definitely dropped by a lot.
- I ended up just partially covering it, which probably defeats the whole 'radiation blocking' purpose, but at least my devices connect.
- It's just a piece of fabric, and if you really want to block signals, you'd need a full metal box, not something you can just tuck around.
- The refund policy is probably there because so many people realize it kills their Wi-Fi.
Frequently Asked Questions
Will this cover block my 5G Wi-Fi signal?
Yes, if the cover effectively blocks RF radiation as claimed (over 60dB shielding, 99.6% effectiveness at 5.6GHz), it will significantly degrade or block your Wi-Fi signal, including 5G, because Wi-Fi operates on radio frequencies.
Can I still use my Wi-Fi devices with this cover on?
For the cover to effectively block radiation, it will interfere with your router's ability to transmit Wi-Fi signals, meaning your wireless devices will likely lose connection or experience extremely poor performance.
Is this cover washable?
No, the manufacturer explicitly states that the copper material with breathable radiation protection fabric is not advised to be washed.
How do I know if it's working to block radiation?
The most direct indication of its effectiveness in blocking radiation would be a significant reduction or complete loss of your Wi-Fi signal, as the cover acts as a Faraday cage. You could also use an EMF meter, but the primary functional consequence is signal loss.
What is the size of the cover?
The cover measures 13.7 x 15.7 inches. Custom sizes are also accepted by contacting the seller.
Buying Guide
When you're looking at products that claim to block Wi-Fi or 5G radiation, you need to understand how wireless signals work. Wi-Fi and 5G are forms of electromagnetic radiation, and for your devices to connect wirelessly, that radiation needs to be emitted by your router and received by your devices. If a product effectively blocks this radiation, it will also block your Wi-Fi signal, making your router unable to provide wireless internet. There's no magic way to block the 'bad' radiation while keeping the 'good' Wi-Fi signal.
RF Shielding (e.g., 60dB)
This number tells you how much the product claims to reduce radio frequency energy. A higher number means more blocking. For a Wi-Fi router cover, a high shielding number means your Wi-Fi signal will be significantly weakened or completely blocked, because Wi-Fi *is* radio frequency energy.
Shielding Frequency Range (e.g., 10MHz to 3GHz, 5.6GHz)
This indicates the specific range of electromagnetic frequencies the product is designed to block. Wi-Fi operates at 2.4GHz and 5GHz (which includes 5.6GHz), so if a cover blocks these frequencies, it will directly impact your Wi-Fi performance.
Material (e.g., copper material with breathable radiation protection fabric)
The material determines how effectively the product can block electromagnetic waves. Materials like copper are conductive and can create a Faraday cage effect, which is what blocks signals. 'Breathable' is important for cooling, but the primary function is signal blocking.
Alternatives
If you're concerned about EMF but need functional Wi-Fi, look for routers with options to adjust transmit power, or consider placing your router in a location further from living spaces, rather than using a signal-blocking cover.
