Precision Hydrogen Inhalation Therapy

Most hydrogen inhalers focus on flow rate or hydrogen production. InhaleH₂ is engineered around how much hydrogen actually reaches the lungs. It is the only system designed to deliver a defined and consistent concentration of hydrogen at the cellular level, (aka Fraction of Inspired Hydrogen - FiH₂) with every breath. 

A patented closed system with a one-way mask valve, stable flow rate, and inflatable reservoir that eliminates hydrogen concentration dilution and accounts for breathing variability. This helps deliver a predictable hydrogen FiH2 concentration within the clinically studied, non-flammable range. Built-in safety controls keep hydrogen levels within safe limits, removing the guesswork and added risk seen with open or high-output systems.

InhaleH₂ replicates how hydrogen has been delivered in clinical research, simplified for personal or clinical use.

Molecular hydrogen inhalation refers to breathing in hydrogen gas (H₂) mixed with air. Inhalation allows hydrogen to enter the bloodstream from the lungs and reach tissues throughout the body without relying on digestion.

Hydrogen is the smallest molecule in the universe, which allows it to move freely throughout the body. It’s neutral, dissipates quickly, and is naturally produced inside you. Because of its unique size and properties, hydrogen can reach inside cells and mitochondria, cross the blood–brain barrier, and act where stress often begins at the cellular level.

InhaleH₂ is engineered with built-in safeguards that regulate H₂ concentration within the clinically studied 1–4% FiH₂ range and automatically shut down if conditions approach unsafe levels. 

Molecular Hydrogen does not accumulate in the body, produces no known toxic byproducts under studied conditions, and is cleared through exhalation. 

With InhaleH₂ it typically takes 20–30 minutes for hydrogen levels in the body to reach equilibrium with the inhaled concentration, making it easy to fit into daily wellness, recovery, or performance routines.

Some users choose longer sessions, and research studies have explored a wide range of durations, including extended use in controlled settings. Researchers are still investigating optimal session length, which can vary depending on study design and application. 

FiH₂, or Fraction of Inspired Hydrogen, is the actual percentage of hydrogen that reaches the lungs with each breath.  FiH₂ is determined by a combination of hydrogen output, total flow rate, and delivery method, not by any single specification alone.

Generator output or flow rate alone does not indicate inspired dose. This is because breathing patterns and air dilution vary widely. InhaleH₂ is engineered to deliver a defined and consistent FiH₂, ensuring predictable exposure within the clinically studied range.

Nasal cannulas are open systems. They allow ambient air to dilute hydrogen with every breath, making FiH₂ unpredictable and/or lower than intended. 

InhaleH₂ uses a closed mask system with a one-way valve and a stabilized reservoir for a consistent, steady, inspired hydrogen. Because of this system, FiH₂ is independent of how shallow or deep each breath happens to be.

Adding oxygen or increasing hydrogen concentration has not been shown to reliably improve hydrogen’s biological effects, but it does significantly increase flammability and safety risk. 

While some claims suggest oxyhydrogen or Brown’s Gas may offer added benefits, there are no conclusive, high-quality clinical studies demonstrating advantages beyond molecular hydrogen alone. Even if additional effects were present, they are most likely attributable to hydrogen itself rather than added oxygen or plasma. 

InhaleH₂ prioritizes precise FiH₂ control within the clinically studied range, where benefits are documented and safety margins are maintained.

The primary difference is how hydrogen enters, moves through, and exits the body. Hydrogen water and hydrogen tablets deliver dissolved hydrogen through the digestive system, and then out to the rest of the body. Hydrogen inhalation delivers hydrogen gas directly through the lungs, allowing rapid diffusion into the bloodstream directly to organs and tissues. This results in faster, higher, and more predictable systemic hydrogen levels.

For optimal performance, we recommend replacing the HEPA filter every 6 months or sooner if dirty. 

Other components such as the mask, tubing, and reservoir do not require routine replacement and should only be replaced if they show signs of wear or damage. Replacement accessories are available directly through our website. 

The system uses distilled water, which helps maintain clean operation and supports long-term use.

InhaleH₂ is manufactured to meet applicable electrical and safety standards for professional equipment. The InhaleH2 system is constructed using medical-grade components and utilizes SPE/PEM technology. The electrolysis electrodes are made of titanium with a platinum coating for durability, corrosion resistance, and hydrogen purity. The manufacturer holds the following certifications: ISO 9001, CE (UDEM), and RoHS. It is not an FDA-cleared medical device and is intended for wellness and research-aligned use, not medical treatment
