Live Safely in a Connected World
Qi devices by Waveguard use proprietary depolarization technology to reduce harmful EMF exposure — without blocking your WiFi or cell signal.
Feel the Difference Every Day
Protect your health, restore balance, and stay connected — all at the same time.
Sleep More Deeply
Wake up rested instead of drained by unseen environmental stressors.
Relieve EMF-Related Discomfort
Headaches, fatigue, and brain fog often lessen when exposure is reduced.
Stay Focused & Clear
A healthier environment supports better concentration and productivity.
Live With Peace of Mind
Whether you're EMF-sensitive or simply proactive, Qi devices help safeguard your space.
Modern Life Surrounds You With Constant EMF Exposure
From WiFi routers and laptops to smart appliances and 5G towers, EMF radiation is now woven into daily life. Research continues to show that persistent, high-level exposure may affect sleep, cognitive function, energy levels, and long-term well-being.
Avoiding it entirely would require disconnecting from modern life — an unrealistic option for most people.

How Qi Technology Protects Your Space
When concentrated, man-made EMFs act like a powerful, direct beam targeting your body.
1
EMF Enters the Field
When concentrated, man-made EMFs act like a powerful, direct beam targeting your body.
2
Depolarization Occurs
The Qi device spreads out the beam, similar to how a prism diffuses light into gentler waves.
3
Natural Form Restored
This replicates the form of natural EMF radiation, which the human body can safely process.
Qi devices don't block EMFs, absorb them, or add competing frequencies. Instead, they transform how EMF waves behave — reducing electromagnetic intensity while allowing you free access to your electronic devices.
Backed by Independent Research
All Waveguard products are supported by 25+ studies, one of the most comprehensive bodies of research in the EMF-protection industry.

Frequently Asked Questions
Everything you need to know about Qi devices and EMF protection.
How does depolarization work?
Depolarization is a proprietary process that transforms concentrated, man-made EMF waves into a more dispersed form that mimics natural electromagnetic radiation. Think of it like a prism diffusing a direct beam of light into gentler, scattered rays. This reduces the intensity of EMF exposure without blocking your device signals.
Will this affect my WiFi or cell service?
No. Qi devices do not block, absorb, or interfere with electromagnetic signals. They only reshape how EMF waves interact with your environment, allowing you to maintain full connectivity while reducing biological impact.
Which device size do I need?
The right device depends on your protection needs: Qi Me provides personal, on-body protection for one individual. Qi-Shield is portable and covers small rooms. Qi-Home Cell protects an entire home. Qi-Max covers large areas like offices or commercial spaces. Many customers start with a Qi-Shield and add home coverage later.
How long do Qi devices last?
Qi devices are built for years of reliable protection. The Qi-Me and Qi-Shield provide up to 5 years of continuous use, while the Qi-Home and Qi-Max offer up to 8 years. When your device reaches the end of its lifespan, you can have it recharged to restore full effectiveness or order a replacement unit. All devices come with a 1-year limited manufacturer warranty.
What symptoms can EMF exposure cause?
Research has associated prolonged EMF exposure with various symptoms including sleep disturbances, headaches, fatigue, difficulty concentrating, and brain fog. Some individuals are more sensitive than others. Many customers report improvement in these areas after using Qi devices.
Does the device need maintenance?
No maintenance is required. Qi devices have no moving parts, require no power source, and work passively. Simply place the device in your desired location and it begins working immediately.
