Electronic – SAVR. Is it even possible to reduce environmental EM radiation without using Faraday cage

electromagnetismemi-filteringradiationRFshielding

Recently I saw a product called SAVR Radiation Reducer in the market by PowerLink claiming the followings:

SAVR Radiation Reducer basically scans and detects EMR waves and it
generates reverse signals to neutralize and reduce low, intermediate &
high-frequency electro-magnetic radiation emitted by computer and
other surrounding devices. Apart from this action, it also filters EMR
waves and flushes it through the A/C power

Significantly reduces EM radiation around your computer and other
devices on WiFi with a coverage area of 4 square meters*

Eliminates over 95% low, intermediate and high-frequency EM radiation

Radiation clearance range up to 1GHz

Basically you just power up the device and place somewhere near you, it will 'reduce' EM radiation around you automatically.

My question is,

  1. Reducing EM radiation? is it even possible this can be done without shielding myself inside a Faraday cage?

  2. Is it possible to scan & generates a 'reversed EM wave' to cancel off or reduce the current environmental EM waves?

  3. If EMR really was reduced to 0 (shown in photo), why the mobile phone still have GSM signal?

  4. If working range claimed up to 1GHz, most GSM band and WIFI band is above 1GHz range (e.g: GSM above 1.8GHz, Wifi 2.4GHz & 5GHz), how reduction was able to archive ZERO (shown in photo)?

This product might as well be filled with fu-fu dust for all the good it will do.

The website provides no details of operation or specific ranges covered. It looks like a cheap watch you could buy anywhere for $10 USD. There are devices called 'jammers' that make broad-band noise that can include audio 'pings' as well as RF sweeps, but these toys cost thousands of US dollars.

They in no way substitute or emulate a Faraday cage, they simple garble sound and/or RF so that packet scanners get mostly useless data. Audio 'pings' can make a hidden microphones AGC (Automatic Gain Control) reset to minimum gain over and over again, hopefully frustrating someone listening in, but a professional spy would use many microphones, some with no AGC to confuse.

This SAVR device is a gimmick. It in no way substitutes for or emulates a Faraday cage. A Faraday cage is a real physical structure with defined shielding properties that contains that which is to be protected from incoming radiation and prevent outgoing radiation. The manufacture makes no claims about frequencies that are covered, or not covered. The advertisements consist mostly of marquee 'splash' words and phrases that collectively add up to nothing.
