NeuroCheck HRV NeuroScan by BrainTap

Here's a simple breakdown:

Hydrogen Output

• HW300 — Delivers 300 mL/min of hydrogen gas. Compact and portable, it's designed for convenient personal or home use.
• HW600 — Produces 600 mL/min of hydrogen gas, offering double the output. This allows for shorter sessions or more frequent use, and is often preferred by those who want higher-capacity performance.

Included Accessories and Features

Both models include accessories that allow multiple types of hydrogen use, such as inhalation, ear application (with headphones), eye application (with goggles), and water infusion.

The HW600 also includes a digital ORP meter, which provides an approximate indication of hydrogen concentration levels in real time. While not intended as a precise scientific measurement, it can give users added reassurance that hydrogen is being produced during use.

Both models deliver the same type and purity of hydrogen gas. The difference is simply the output volume:

• HW300: 300 mL/min
• HW600: 600 mL/min

This means the HW600 produces hydrogen twice as fast. To receive a similar total volume of hydrogen, a session on the HW300 would need to be about twice as long as one on the HW600.

So yes — you can achieve a comparable experience with either device; the HW600 is just more time-efficient.

For new users:

• Start gradually with 15–30 minutes per session to get comfortable.
• Focus on relaxed, steady breathing.
• Over 1–2 weeks, you can increase to 1–2 hours daily, based on preference.
• Some users prefer using the device several times a week instead of daily.

Your routine can be flexible — there's no single "right" way. The best approach is to experiment and see what fits your lifestyle.

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.

There is no guarantee of specific health results with any H₂ system. Every body is different, and responses to hydrogen therapy can vary based on many factors like lifestyle, existing conditions, and overall health.

That said, we've seen incredible feedback from customers around the world — but we always recommend trying the product consistently and seeing how your body responds.

Both options deliver molecular hydrogen, but in different ways:

• Machines — Provide a steady stream of hydrogen gas for inhalation or water infusion, making them practical for longer or repeated use.
• Supersaturated Hydrogen (SSH) Tablets — Taken orally, where they release hydrogen in the stomach. Some people find this convenient when traveling or looking for a quick option.

Machines are often preferred by those who want unlimited access without restocking, while tablets are portable and simple. Many of our customers like using both, depending on the situation.
