Hydrogen water Diffusion Stone in stainless steel

20 micron pore size. Finer pores create smaller bubbles, which increases the water’s surface-area contact with hydrogen gas and supports better dissolution into the water rather than just bubbling through and escaping.

It’s designed as a universal attachment for hydrogen gas output lines via its hose connection, intended to work with your existing hydrogen inhaler rather than being locked to one specific model.

The stone is rated to achieve up to 1.5 ppm in water within minutes of attachment, depending on your machine’s gas output rate.

316 stainless is a food/medical-grade alloy commonly used in water-contact applications specifically because it resists corrosion and doesn’t leach into water the way lower grades can.

Since output is tied to pore size, periodic cleaning (a citric acid soak, similar to bottle maintenance) prevents mineral scale from reducing bubble fineness and hydrogen transfer efficiency over time.
