Here’s a breakdown of the main distinctions:

Hydrogen Output:
The HW300 produces 300 mL/min of pure hydrogen gas, which is ideal for personal use and provides effective hydrogen therapy in a manageable, compact form.

The HW600, however, produces 600 mL/min, doubling the hydrogen output and allowing for faster and potentially more efficient therapy sessions. This higher output can be particularly beneficial for customers looking for more intensive use or faster sessions, or smaller clinic.

Included Accessories and Features:
Both models come with all necessary accessories to perform multiple types of therapy, including inhalation, ear therapy (with specialized headphones), eye therapy (using eye goggles), and water infusion capabilities.

Additionally, the HW600 includes a digital hydrogen meter, allowing users to monitor and confirm hydrogen levels in the water. This added tool provides reassurance of the hydrogen concentration, which can be especially valuable for those using hydrogen therapy regularly. With the HW600, customers also gain access to a course at the Molecular Hydrogen Institute. This course is an excellent resource for learning about hydrogen therapy and understanding its effects on health at a deeper level.

Yes, customers can achieve similar results with the HW300 model ($3,500); however, it will require more time. Since the HW600 produces double the amount of pure hydrogen (600 mL/min) compared to the HW300 (300 mL/min), we recommend that customers using the HW300 increase their session duration to compensate. Specifically, they should aim for a minimum of 2 hours of inhalation daily with the HW300 to match the effectiveness of a 1-hour session with the HW600.

FOR NEW USERS:

• Start with 15-30 minutes per session to assess tolerance.
• Practice slow, deep breaths every few respirations to maximise gas absorption.
• Gradually increase to 1-2 hours daily over the first 1-2 weeks.
• Watch for detox symptoms (e.g., headache, nausea) and reduce duration if needed.
• Slowly build back up.
• If you do not have chronic conditions, use the machine 3 – 4 times a week. Time: minimum 1 hour per session with HW600 or 2 hours per session for HW300.

  If you have chronic conditions, please contact us at info@axiomh2.com and we will give you more guidelines that match your specific condition. 

Yes, this is completely normal. The HW300 and HW600 are designed to deliver pure hydrogen gas gently and subtly, which means you may not feel a strong airflow. Unlike oxygen, hydrogen is a much lighter gas, so it diffuses differently and is not always perceptible during inhalation.

For those who prefer a stronger flow sensation, our commercial units provide a more noticeable hydrogen output.

Our machines are designed for minimal maintenance, but regular care ensures optimal performance and longevity.

Water Quality: Always use pure distilled water to prevent mineral buildup and extend the lifespan of the machine.

Cannulas & Accessories: Should be disinfected regularly and given a deep clean every few months to maintain hygiene.

Infusion Rod (for Water Infusion): If using mineralized water, occasional cleaning may be needed to prevent clogging.

HW300 & HW600: These models require very little upkeep beyond keeping the water level between minimum and maximum marks.

Commercial Units: Built for heavy daily use, these may require periodic checks, especially in professional settings.

While both hydrogen machines and SSH tablets provide molecular hydrogen, they differ in delivery method, concentration, and absorption:

Machines produce continuous hydrogen gas for inhalation and water infusion, delivering a steady supply of hydrogen over time. 

SSH Tablets are taken orally, releasing molecular hydrogen directly in the stomach, where it is absorbed through the digestive tract. This makes them particularly beneficial for gut health and systemic antioxidant effects.

If you have a chronic condition, we highly recommend investing in one of our machines, as inhalation provides a more consistent and efficient hydrogen intake over extended periods.

Additionally, if you plan to use hydrogen therapy long-term, relying solely on tablets can become costly over time, whereas a machine provides unlimited hydrogen production with minimal upkeep.

Yes, we ship worldwide and work with a DHL agent for orders outside the U.S.

For Costa Rica, machines are exempt from import duties, but for other countries, import taxes and regulations vary based on local laws. We recommend checking with your country’s customs office for specific details.

If you’re unable to purchase machines or tablets on our website, it likely means we haven’t shipped to your country before and need to verify import regulations before processing orders.
