The SPIRO® SQUARE uses the natural nanomagnetic properties of the SPIRO® material (contained within the card) to function as a passive filter for high-frequency telecommunications waves. With an action range of 8 feet (2.4 meters) radius, it is 2.3 times more powerful than the SPIRO® CARD, and it can handle the emissions from up to 7 different devices at the same time. To use, simply place the square near the devices. This is ideal for IT personnel or people who use multiple electronics. This filter has been found to not affect the performance of the devices it is used with; on the contrary, laboratory tests have shown that it is fully compatible with them, optimizes their operation, and lengthens their useful life.


Protection from WiFi & Computer Radiation

Multifrequency Filter Protection for RFR / ESD / LF Magnetic Flux

SPIRO® SQUARE is a thin, square-shaped card that is capable of protecting you and filtering both types of radiation from wireless routers, laptops, desktops, multiple electronic devices, and household appliances.

It has a specialized formulation for telecommunications signals of multiple frequency bands, it works as personal protection for technical workers who use multiple electronic equipment and frequent places of greater exposure.


SPIRO® formulation specialized in multiple WiFi / Bluetooth Radiations and clean telecommunications interconnectivity. 

The product will protect users from the harmful effects of EMF, filtering direct radiation emissions from multiple devices, especially for domestic WiFi Routers and Extender WiFi, WiFi 2.4, WiFi5, WiFi6 / Bluetooth 5 Transmitters / Microwave Ovens / Vehicle running on Gas / Smart TVs / Video Game Consoles / Radiation from Laptops and Desktop Computers. 

How does it work?

The SPIRO® SQUARE is based on NOXTAK’s patented and scientifically proven technology: a nano-composed (nanotechnology) material that filters out the interferences and disturbances in artificially-generated EMF radiation by organizing radiation spins (Spin Radiation Organizer – SPIRO®), which makes it behave the same way as beneficial natural EMFs. 

This product contains 7 broad-spectrum SPIRO® films, giving it a protection area of 194 square feet or 18 square meters from microwave background radiation.

Unlike anti-radiation products, SPIRO® SQUARE is the only solution that protects you from all types of radiation emitted by devices, such as Wi-Fi and wireless signals, as well as from the generation of ELF fields, while reducing interference, improving connectivity, performance, and energy efficiency of your devices.

How to use it?

WiFi Routers:

  • Place it just beside the router or above it.
  • Place it in the same shelf, less than 20 cm (8”) from the device.

In laptops: 

  • It can be placed just beside the laptop, less than 20 cm (8”) from the device.
  • If you use a case for your laptop, place it between the case and the back of the laptop’s screen. This is the ideal placement for the card.

Desktop Computers: 

  • It should be placed at a central point between the screen and the keyboard. 

Conventional gas vehicles: 

  • It must be placed in the central area of the vehicle. Between the driver’s and co-pilot’s seats. This way, you can fully take advantage of the 8 ft action range, covering the passengers too. 

Benefits of the SPIRO® SQUARE

  • Filters and protects from multiple harmful emissions from WiFi routers and Bluetooth transmitters
  • Reduces multiple interferences and optimizes connectivity between devices
  • Reduces static and extends the useful life of electronic devices
  • Larger protection area up to 194 square feet or 18 square meters
  • Works in proximity to devices and does not require to be stuck to devices

Studies have shown an improvement in Heart Rate Variability and a better response in situations of work stress and anxiety has also been reported, increasing the benefits with the time of permanent use.
