1. What Is RO Water Filtration?
Reverse osmosis (RO) pushes water through a fine membrane under pressure. This process removes:
-
Dirt and sediment
-
Chemicals like chlorine and pesticides
-
Heavy metals (lead, arsenic)
-
Most dissolved minerals (calcium, magnesium)
You get almost pure, safe drinking water.
2. Does RO Water Really Lose Minerals?
Yes. RO removes up to 99% of minerals. But:
-
Tap water has low minerals. Typical tap water has about 50–200 mg/L of total dissolved solids (TDS).
-
Minerals from water are small. Even if you drank 2 L of tap water, you’d get only 100 – 400 mg of minerals.
3. Why Your Diet Is Your Main Mineral Source
Your meals give you far more minerals than water:
| Food Type | Key Minerals | Amount per Serving |
| Milk (250 mL) | Calcium (300 mg) | 300 mg |
| Spinach (1 cup) | Iron (6 mg) | 6 mg |
| Almonds (30 g) | Magnesium (80 mg) | 80 mg |
| Banana (1 medium) | Potassium (422 mg) | 422 mg |
Tap water (250 mL) only gives 20–50 mg calcium.
4. Will “Demineralized” Water Harm You?
No—if you eat well:
-
Health groups don’t require minerals in water. Clean water safety is the top goal.
-
Balanced meals give enough minerals. Fruits, veggies, grains, dairy, nuts, and lean meat cover your needs.
-
Optional boost: Add a mineral cartridge after RO, or drink mineral water now and then.
