Answer Summary
Choose Signal Tamer if you want to reduce WiFi EMF without replacing your router. Choose JRS Eco Router if you want a complete low-EMF system with zero emissions when idle.
Signal Tamer is a $63 shielding pouch that blocks 90-95% of emissions from any router. JRS Eco Router ($485) replaces your router with hardware that cuts beacon pulses by 90% and goes silent when nothing is connected. Your choice depends on budget and coverage needs.

How Signal Tamer Works
The Signal Tamer is a Faraday-cage-style shielding pouch made from woven nickel, copper, and polyester mesh. You slide it over your existing WiFi router, and the conductive fabric blocks 90-95% of the radio frequency emissions from reaching you.
The mesh design allows airflow so your router doesn’t overheat. It also doesn’t require you to change any settings or replace any hardware. The tradeoff: as it blocks EMF, it also reduces your WiFi signal range.
Signal Tamer comes in two shielding strengths:
| Strength | EMF Reduction | Best For |
|---|---|---|
| Regular | ~90% | Normal WiFi use with reduced EMF |
| Extra | 97-99% | Hardwired setups or router near workspace |
You can adjust coverage by sliding the pouch up to expose more of the router. This gives you control over the balance between EMF reduction and WiFi range.
The Signal Tamer is available in Standard (10″ x 16″) and XL (22″ x 26″) sizes.
How JRS Eco Router Works
The JRS Eco Router takes a different approach: it reduces EMF at the source rather than blocking it after emission. Created by Dutch electronics engineer Dr. Jan-Rutger Schrader, it uses a standard Asus router with custom JRS Eco firmware that fundamentally changes how the router broadcasts.
Standard routers send out beacon pulses ten times per second, around the clock, announcing their network name. The JRS Eco Router reduces this to once per second when idle. That’s a 90% reduction in background radiation even before you consider its other features.
The most impressive capability: when no devices are actively connected, the router enters a zero-EMF standby mode. It stops all wireless transmission completely. When your phone or laptop reconnects, the router wakes up instantly.
| Feature | Standard Router | JRS Eco Router |
|---|---|---|
| Beacon pulses | 10 per second | 1 per second |
| Emissions when idle | Continuous | Zero |
| Power adjustment | Limited/complex | Simple slider |
| Scheduled on/off | Usually unavailable | Built-in |
The router also includes a physical on/off button and a scheduler for automatic shutdown at night. You can fine-tune transmit power with an on-screen slider instead of digging through router admin settings.
The JRS Eco Router provides AX4200 WiFi speeds and covers up to 2,500 square feet.
Head-to-Head Comparison
EMF Reduction Approach
Signal Tamer works like a shield between your router and your living space. The metal mesh blocks emissions from traveling toward you. This is effective but directional. EMF still exists inside the pouch.
JRS Eco Router reduces emissions at the source. Fewer beacon pulses means less total radiation generated. Zero-EMF standby means no emissions at all during idle periods. The reduction is systemic rather than directional.
WiFi Coverage
Signal Tamer reduces your WiFi range proportionally to how much EMF it blocks. If you need strong coverage throughout a large home, this creates a tension between protection and connectivity.
JRS Eco Router maintains normal WiFi coverage while reducing emissions. You can still adjust power levels down, but the default configuration provides full coverage with reduced radiation.
Setup Complexity
Signal Tamer requires no technical knowledge. Remove from packaging, slide over router, done. Adjustment means simply moving the pouch up or down.
JRS Eco Router requires disconnecting your old router, connecting the JRS to your modem with an ethernet cable, and potentially adjusting settings. The process is straightforward but involves more steps.
Ongoing Use
Signal Tamer is set-and-forget. No settings to manage, no firmware to update.
JRS Eco Router offers more control but requires occasional interaction. You might adjust power levels, set schedules, or check the Eco status indicator.
Best For: Budget-Conscious Buyers
If you want to reduce WiFi EMF without a significant investment, Signal Tamer is the clear choice. At $63 versus $485, it’s roughly 85% less expensive.
Signal Tamer works particularly well if:
- Your router is near your workspace or bedroom
- You primarily use ethernet for your main devices
- You want a quick solution you can implement today
- You rent and can’t make infrastructure changes
The tradeoff is reduced WiFi range. If you need whole-home coverage, you may need to accept less EMF reduction or consider the JRS alternative.
Best For: Whole-Home Protection
If you need WiFi coverage throughout your home while minimizing EMF, JRS Eco Router delivers both. The firmware-level approach means you don’t sacrifice range for protection.
JRS Eco Router works particularly well if:
- You have a multi-story home or large floor plan
- Multiple family members use WiFi simultaneously
- You want automated features like night scheduling
- You prefer reducing EMF at the source rather than blocking it
The investment is significant, but you’re getting a premium router with built-in EMF management that would be difficult to replicate with standard hardware.
Best For: Maximum EMF Reduction
For the lowest possible WiFi EMF exposure, combine both approaches: use an ethernet connection for your primary devices and cover your JRS Eco Router with a Signal Tamer Extra Strength during periods of wireless use.
This layered approach gives you:
- 90% reduction from reduced beacon pulses
- Additional 97-99% shielding from the Signal Tamer
- Zero emissions during idle periods
- Maximum protection during active use
SYB offers a Safer WiFi Bundle that includes Signal Tamer alongside other protection products.
What They Don’t Do
Neither product eliminates WiFi EMF entirely. Both reduce exposure significantly, but if you’re using WiFi, some radiation is present.
Signal Tamer does not:
– Maintain full WiFi range while blocking EMF
– Reduce EMF from your modem (if separate)
– Work with mesh WiFi systems (multiple units)
– Change anything about how your router operates
JRS Eco Router does not:
– Work as a standalone modem (requires existing internet connection)
– Block EMF from other sources like smart meters or cell towers
– Provide shielding. It reduces emissions but doesn’t block them from traveling
– Eliminate EMF during active use (only during idle)
If you need zero WiFi and health concerns, the only solution is to disable WiFi entirely and use hardwired ethernet connections. Both products represent different approaches to WiFi router radiation safe distance considerations, and using a best EMF detector can help you measure the effectiveness of either solution.
Frequently Asked Questions
Yes. The JRS Eco Router reduces emissions at the source, and Signal Tamer provides additional shielding. This layered approach offers maximum EMF reduction for those who want WiFi available but minimally impactful.
It depends on your usage pattern. During active WiFi use, Signal Tamer Extra Strength (97-99% blocking) provides greater reduction than JRS Eco's 90% beacon reduction. However, JRS Eco Router offers zero emissions when idle, which Signal Tamer cannot match. Over a full day with intermittent use, total exposure may be similar.
No. Signal Tamer blocks the wireless signal, not your internet connection. If you connect devices via ethernet, speed is unaffected. WiFi speed to devices within the reduced range remains normal. Only WiFi range decreases, not speed.
Basic comfort with connecting cables is sufficient. You plug the JRS into your modem with an ethernet cable, power it on, and connect your devices to the new network name. The Eco features work automatically. Advanced settings are available but not required.
Signal Tamer comes in two sizes: Standard (10" x 16") and XL (22" x 26"). The XL fits most routers including those with external antennas. If your router is larger, the Signal Tamer can still partially cover it for reduced (but not optimal) shielding.
Yes. The JRS Eco Router is compatible with all major providers including Xfinity, Verizon, AT&T, and Spectrum. You connect it to your existing modem or gateway. It doesn't replace your modem, just your router.
