Frequently Asked
Questions

How much does the NanoVi™ device cost?

Due to an agreement with international resellers, we do not list prices on our website. To discuss purchasing options, please call +1 206 525 0227 or click here to request pricing.

Who uses bio-identical signaling?

Our customers include doctors and health-conscious people who are interested in anti-aging, preventing disorders, enhancing energy, recovering from illness or better management of chronic diseases. Athletes seeking peak performance, faster recovery times and improved immune function are also dedicated users this technology.

Are there any dangers of using the device?

Absolutely none. Breathing with the device is just like the breathing you do every day, only better because it boosts oxidative response at the cellular level. Bio-identical signaling helps trigger natural repair mechanisms, supporting rather than overriding the body’s natural ability to function.

Does the NanoVi device produce EMF?

Some EMF is unavoidable for any electrically powered device. Eng3 has used all possible means and employed state-of-the-art engineering to reduce EMF as much as possible. This includes selecting components to minimize EMF, avoiding the generation of unnecessary EMF, and incorporating appropriate shielding in all NanoVi devices. As a Medical Device registered with the US FDA and their regulatory counterpart in Europe, the law requires that all medical devices pass EMF risk analysis during a risk management evaluation. EMF emission testing was done by an independent and certified testing facility in Germany where medical devices must comply with rigorous EMF standards. We appreciate your concerns about EMF and have paid a great deal of attention to this issue.

Does the NanoVi have a grounded plug?

Laws in the US and Europe require that medical devices used in professional settings have three-pronged or grounded power cords for the power supply. Additional requirements for medical devices mandate that devices used in homes have two-pronged or ungrounded power cords for their power supply. Without the correct cords, devices are not allowed to be brought in or to the market. In situations, where a non-professional user is interested in using the three-pronged, grounded power cords for their power supply, we are able to supply a “NanoVi–Wellness” device. The “NanoVi–Wellness” device is not a medical device but falls in the category of household appliance. In this case, Eng3 is allowed equip NanoVi devices with a three-pronged/grounded power cords for the power supply.

Does the NanoVi™ device deliver concentrated oxygen?

No, the oxygen level is the same as regular air, about 21%. In some acute situations, concentrated oxygen such as in hyperbaric chambers can be helpful and even life-saving. However, concentrated oxygen creates free radicals that will ultimately damage cells and health.

Is NanoVi™ the same thing as bio-identical signaling?

NanoVi™ is the product name, bio-identical signaling is the term used for the type of therapy. NanoVi Eco™, NanoVi Pro™, and NanoVi Exo™ devices are the only products that have been proven through university research to be “bio-identical.”

How do scientists know that bio-identical signaling actually works?

Researchers have measured impact from use of the technology across a variety of indicators. These include heart rate variability, basal metabolic rate, blood oxygen levels, resting heart rate, levels of unused exhaled oxygen, markers for immune response, measures of oxidative stress, and lactate production in athletes.

Is this device similar to ozone therapy?

Not at all. It is designed to enhance cellular activities, including the metabolism of oxygen. Ozone (O3) has a different purpose, it is used to kill bacteria, viruses and fungus. Ozone, when introduced through the blood can increase oxygenation. Ozone is toxic in high doses.

How does it relate to hyperbaric chambers?

NanoVi™ technology complements hyperbaric treatments. Hyperbarics are especially valuable for critical healing like for burn victims or people with strokes. Because more oxygen is pressed into the system, there is also more oxidative damage. The NanoVi™ device is very complementary and can be used long term. Since it initiates the repair of free radical damage, people doing hyperbarics benefit from using NanoVi™ technology as well.

What is the difference between NanoVi Eco™, NanoVi Pro™, and NanoVi Exo™?

The main difference is the amount of time spent using the device. For the same benefit, you spend twice as much time using the NanoVi Eco™ device as the NanoVi Pro™. The Pro device takes twice as long as the NanoVi™ Exo device. The Pro and Exo devices also include Smart Card technology that works like a pre-paid phone card, where minutes are deducted from the card with use. This is great for self service. The NanoVi Pro™ and Exo devices also come with a support pack including brochures and other materials for professionals to use with their clients. All three devices come with everything you need to use the device, but the two more powerful devices also come with more nasal cannulas.

Are there maintenance costs for NanoVi™ devices?

No. The only added cost is the small amount of electricity it draws while in operation, the small cost of replacing the cannula or paper tube, and replacing the distilled water every few days.

Is there a payment plan?

Leasing is available for personal and commercial accounts. We can work with any leasing company or obtain leasing through ours. Call us to explore leasing options.

How big is it?

The footprint of all three devices is less than one square foot (11 inches x 12 inches). They are 9 inches tall, including the height of the glass bottle. These devices weigh about 9 pounds.

Is there a return policy?

Yes, they can be returned within 30 days and there is a small restocking fee.
