Lourdes Hydrogen Water Machine: HS-71 Specs vs. Hydrion Flux

If you’re considering the Lourdes HS-71 hydrogen water machine and want to know how it compares with other machines, the safest starting point is the two manufacturers’ own publicly available specifications. The Lourdes HS-71 page describes its electrolysis method, warranty and maintenance schedule, but does not give a hydrogen concentration in PPB. By contrast, the Hydrion Flux specifications table provides purity, a PPB value and a flow rate. Below, we go through exactly what the two pages state, point by point, and take a separate look at which health claims are made without citing research.

• After 20 minutes of enrichment, the Lourdes HS-71 gives an rH2 reading, not a PPB value, so the hydrogen output of the two machines cannot be compared using a single number.
• The Hydrion Flux’s own page gives purity, PPB concentration and flow rate, all supported by measurements.
• The reseller’s page links hydrogen water to diseases without citing studies; this is better treated as marketing copy than as fact.
• Maintenance, filter replacement and cleaning are recurring tasks for both machines, not a one-time decision you make when buying.

What to compare in a hydrogen water machine

Before putting the two specific machines side by side, it’s worth clarifying which criteria can actually be used to compare them. A publicly stated concentration value (PPB) tells you more than any marketing label, because it can be checked and linked to measurement conditions; a phrase such as "highly enriched" tells you nothing on its own about how much hydrogen you get in a glass of water. The electrolysis method—whether the machine uses an SPE/PEM membrane or another technology—also directly affects maintenance: in some machines, the membrane needs replacing, while in others, the filter is the main item to replace. The warranty and consumables, such as filters or nasal cannulas, are not one-time expenses but recurring costs spread over several years, so it’s worth factoring them in before choosing between machines and water types. If you’d like to think through this decision in a broader context too, our comparison of machines, bottles and pitchers will help you place the Lourdes HS-71 and Hydrion Flux within a wider category.

The Lourdes HS-71: what the manufacturer’s and reseller’s pages actually state

The Lourdes HS-71 uses square-wave pulsed direct-current electrolysis, and according to the reseller’s page, after 20 minutes of enrichment the water gives an rH2 reading in the range "rH2=0-8" (source: Lourdes HS-71 product page). This is a redox-type scale, not a hydrogen concentration expressed in ppb or ppm, which is an important distinction when you want to compare it with another machine. The machine weighs 2.7 kg, comes with a three-year warranty and requires distilled or reverse-osmosis-treated water. The page recommends cleaning two to three times a week and replacing the filter every six months. Neither the lourdes.hu website nor the reseller’s page gives the machine’s hydrogen concentration in PPB or ppm—this information is simply absent from the publicly available materials; instead, the manufacturer gives the redox-type measurement described above.

The Hydrion Flux’s technical specifications for the same points

Looking at the same four criteria, the Hydrion Flux’s own product page gives a hydrogen purity of 99.99%, a water concentration of at least 4,000 PPB and a hydrogen flow rate of 500 ml/min, using SPE/PEM ion membrane electrolysis. The machine offers three water temperatures—room temperature, lukewarm and hot—and combines drinking water dispensing and inhalation mode in a single device, with no installation required: just plug it into an outlet. For a more detailed explanation of the electrolysis method and why membrane type matters for purity and maintenance, our article on SPE/PEM electrolysis is for those who want to compare it with the Lourdes HS-71’s square-wave pulsed method. It’s important to be clear: a higher PPB value by itself does not mean a machine produces "healthier" water, only that the water contained more dissolved hydrogen at the time of measurement—this is a comparable technical specification, not a health verdict.

PPB and rH2: why the two numbers are not the same

PPB (parts per billion) indicates how many milligrams of hydrogen gas dissolve in one liter of water, and is typically measured immediately after enrichment at a specified temperature—that’s why the PPB values of two machines can be compared if you also know the measurement conditions. By contrast, rH2 is a redox potential-based reading that indicates the water’s oxidation-reduction state and cannot be directly converted into a hydrogen concentration. The two scales describe different physical quantities, so based on the information currently available, the Lourdes HS-71’s "rH2=0-8" reading and the Hydrion Flux’s 4,000+ PPB value cannot be compared using a single common number. If you choose a hydrogen water machine and being able to measure its concentration is important to you, look specifically for a PPB or ppm value and the measurement conditions on the product page, rather than redox-type or other indirect indicators. Our article explaining PPB in detail also helps you understand how to read a manufacturer’s specifications table correctly.

Health claims to treat with caution

Among the health-related claims, the Lourdes HS-71 reseller’s page deserves particular attention: it links hydrogen water to conditions such as cancer, diabetes and high blood pressure without citing a single study (source: Lourdes HS-71 product page). This kind of wording is typical of marketing copy in the industry and should not be considered medical evidence, regardless of which brand’s page it appears on. Neither the Lourdes HS-71 nor the Hydrion Flux is a medical treatment, and hydration devices and preliminary research into molecular hydrogen are two different things: one is a household device, while the other is an ongoing field of scientific research whose findings do not yet establish an effect against specific diseases. If you’re interested in the actual state of research rather than relying on the wording of a sales page, our article on the safety of hydrogen water and common misconceptions gives an overview of what studies actually support.

Which one is a better fit for your situation

If inhalation is just as important to you as enriching drinking water, that alone narrows down the relevant machines, since not every hydrogen water machine offers an inhalation mode: the Lourdes HS-71 enriches drinking water only, while the Hydrion Flux combines both functions in one device. If being able to verify the concentration is a key consideration for you, a published PPB value, such as the one provided for the Flux, can serve as a concrete filter, while a redox-type reading alone does not allow for comparison. Your tolerance for maintenance is also a real factor in the decision: if you don’t want to replace a filter every six months or clean the machine several times a week, it’s worth checking which machine requires less regular attention with your own water hardness and usage frequency. If you’re looking for a different design from the Flux but want a similarly combined drinking water and inhalation function, it’s also worth checking the specifications of the Hydrion Onyx. And if you’d like to look more broadly at hydrogen water machines available on the market, independently of the Lourdes and the Flux, our comparison of home hydrogen water machines puts additional machines side by side using the same criteria.
