Reverse osmosis vs. Valinor
RO strips the minerals along with the contaminants.
It pushes water through a plastic membrane that rejects 95–99% of total dissolved solids — contaminants and healthy minerals alike.
Side by Side
Valinor vs. Reverse Osmosis
RO rejects nearly everything dissolved in water. Valinor targets contaminants and retains minerals.
Compared to under-sink reverse osmosis systems — the standard residential configuration.
| Valinor | Reverse Osmosis | |
|---|---|---|
| Method | Selective filtration. Targets contaminants, retains minerals | Total rejection. Strips nearly everything |
| Healthy minerals | Retained — calcium, magnesium, potassium | Stripped — requires remineralization post-filter |
| Taste | Natural. Minerals preserved | Flat / demineralized |
| Water temperature | Fridge-cold or room temp | Tap temperature at the faucet |
| Materials | Glass and stainless steel vessel | Plastic membrane, plastic tubing; water stored in a plastic bladder |
| Installation | None. Unbox and pour | Plumbing modification; often professionally installed |
| Works for renters | Yes | Not typically — requires plumbing access |
| Water waste | None | Traditional units waste 3–4 gallons per gallon; high-efficiency units run roughly 1:1–2:1 |
| Hardware cost | $299 | $300–$2,000+ installed |
| Annual filter cost | $260/yr (subscription) | $100–$500+/yr depending on system |
| Contaminants reduced | 75+ | Nearly all |

What RO does to your water
Closer to distilled water than drinking water.
Calcium, magnesium, and potassium aren’t impurities. They’re electrolytes — they regulate fluid balance and cellular function. RO strips all of them.
A WHO-commissioned review found adverse effects from long-term consumption of demineralized water, and epidemiological studies associate low calcium and magnesium in drinking water with increased cardiovascular risk. (Kozisek, F. “Health Risks from Drinking Demineralised Water.” Nutrients in Drinking Water, WHO, 2005.)
Most people already under-consume magnesium and potassium. RO doesn’t cause deficiency — it strips the buffer that protects against it. Some systems add a remineralization stage to restore what’s lost. In one independently tested system, it didn’t close the gap:
“It seems that even though the filter reintroduces trace minerals back into the water, the concentrations of minerals added aren’t equal to those reduced, which means there’s still a mineral reduction overall.”

↓ 93%
Calcium
Nerve signaling and muscle contraction.

Magnesium
Cellular energy production and muscle relaxation. One of the most under-consumed minerals in modern diets.
↓ 100%
Potassium
Cellular hydration — works alongside sodium to move water into cells and support muscle and heart function.
↓ 91%
Sodium
Water absorption in the gut and maintaining blood volume. Relevant for active, high-sweat individuals.
