Cost Per Liter
MediumConsider long-term value, not just upfront price
💡 Pro Tip: Calculate True Cost
Don't just look at upfront price. Calculate the 5-year cost per liter:
- • PureONE: $2,495 ÷ 18,250 liters = $0.13/liter
- • Portable bottles: $249 ÷ 3,650 liters = $0.68/liter
- • H2 tablets: $40/month × 60 months = $2,400 total
* Based on 10 liters/day for countertop, 2 liters/day for portable
Frequently Asked Questions
What PPM level do I need for therapeutic benefits?
Research shows therapeutic benefits begin at 0.5 PPM, with optimal results typically seen between 1.6-3.0 PPM. Higher isn't always better - consistency and proper dosing matter more than maximum PPM.
Should I get a portable or countertop hydrogen water machine?
Choose countertop for home use if you drink 2+ liters daily and want lowest cost per liter. Choose portable if you travel frequently or only drink 1-2 glasses daily. Many users have both.
How long do hydrogen water machines last?
Quality SPE/PEM machines typically last 5-10 years with proper maintenance. Key factors are electrode quality, cleaning routine, and water quality. Avoid cheap units that fail within months.
Is a $2000+ hydrogen generator worth it?
For daily therapeutic use, premium machines offer better value long-term. They produce more hydrogen, last longer, and cost less per liter than bottles or tablets. Calculate your 5-year total cost.
What's the difference between SPE/PEM and regular electrolysis?
SPE/PEM (Solid Polymer Electrolyte/Proton Exchange Membrane) produces pure H2 gas without harmful byproducts. Regular electrolysis can create chlorine, ozone, and other contaminants. Always choose SPE/PEM.
