Published studies, measurable results
SPIRO technology has been tested through double-blind clinical trials, independent HRV assessments, certified SAR measurements, and longitudinal field studies. Every claim traces back to data. The reports are linked below in full.
Clinical Trials
Double-blind, controlled studies on biological outcomes
Sleep Quality Test
Participants using SPIRO reported significant improvement in overall sleep quality. The control group reported a decrease over the same period. The study measured subjective sleep metrics across both groups under blinded conditions.
Read full reportStress Response Test
The stress index decreased or stayed in the optimal zone for all participants using SPIRO. They also reported increased energy levels, and body balance improved in most cases. The control group showed no equivalent changes.

Independent biophysical testing by IGEF across four exposure scenarios
Cellphone Radiation Exposure
The SPIRO Card showed beneficial effects on heart and circulatory processes during cellphone use, reducing the autonomic nervous system's effort to maintain internal balance under near-field RF exposure.

The SPIRO Square showed beneficial effects on cardiovascular and autonomic function during continuous Wi-Fi router exposure, reducing the vegetative nervous system's regulatory burden.
Read full reportELF Near-Field Exposure
The SPIRO Disc demonstrated measurable improvements in heart and circulatory function under extremely low frequency (ELF) exposure from nearby appliances and wiring, reducing autonomic stress markers.
Read full reportOutdoor EHF (Extremely High Frequency) Exposure
Multiple SPIRO Discs used together showed beneficial effects on heart and autonomic function under outdoor high-frequency exposure from cell towers and antennas, reducing the nervous system's compensatory effort.

Certified lab measurements of radiation absorption and antenna compliance
SAR Test — Peak Radiation Emissions Reduction
SPIRO reduces the amount of radiation absorbed by the human body by reducing emission peaks. Testing conducted by Morlab using standard SAR measurement protocols with tissue-simulating phantoms.
Read full reportSAR Measurement Evaluation (EN62209-2)
SAR test following the EN62209-2 standard with a robotic arm and tissue-simulating phantom. The SPIRO Card reduced SAR values when used with a router, validated within acceptable measurement uncertainty limits.
Read full reportCE RF Test Report — Antenna Performance
Radiated power and sensitivity testing across GSM900, GSM1800, and WCDMA2100 bands. The SPIRO Card performed within acceptable power and sensitivity limits, confirming RF compliance with no degradation to device performance.

Over-the-air antenna pattern tests confirming SPIRO does not degrade wireless signals
WiFi Signal Improvement
SPIRO produced a measurable improvement in the antenna propagation pattern of wireless hotspots. The test confirmed that SPIRO filtering does not reduce signal strength and can improve propagation characteristics.
Read full report4G Cellphone Signal
SPIRO produced an improvement in the antenna propagation pattern of a 4G mobile device. Signal quality was maintained or improved, confirming that SPIRO's filtering mechanism does not interfere with telecommunications.

Longitudinal patient studies and GDV bioenergy assessments
EHS Management — 357 Patients (2014–2018)
A four-year longitudinal study tracking 357 patients with symptoms related to electromagnetic hypersensitivity. 71% of patients using SPIRO filters experienced significant reduction in symptoms including fatigue, anxiety, and sleep problems, within an average of 27 days.

Using Gas Discharge Visualization, this study compared energy levels in eight subjects during phone use with and without the SPIRO Card. 75% of participants showed significant changes in organ-level energy readings when the SPIRO Card was applied.
Read full reportEnvironmental Energy — 4G/5G/WiFi/Bluetooth Radiation
Using GDV technology and the Sputnik sensor, this study measured how SPIRO filters affected environmental energy balance in areas exposed to high electrosmog from 4G LTE, 5G, Wi-Fi, and Bluetooth. SPIRO application significantly reduced electromagnetic interference and improved environmental energy readings.
