Does filtered purified water contain minerals? The answer depends entirely on the filtration technology you choose. While some systems are designed to strip everything but the water molecule, others are built to target contaminants while leaving healthy trace elements untouched. Understanding the difference is key to choosing the right system for your home.
Comparing Filtration Technologies
Currently, two of the most popular home water treatment methods—Ultrafiltration and Reverse Osmosis—handle minerals in very different ways:
1. Ultrafiltration (UF)
With a pore size of 0.01 microns, Ultrafiltration acts like a fine sieve. It captures rust, bacteria, and viruses but allows dissolved minerals like calcium and magnesium to pass through, maintaining the water's original mineral profile.
2. Reverse Osmosis (RO)
As an ultra-high precision technology (0.0001 microns), RO removes almost 99% of all total dissolved solids (TDS). This includes harmful heavy metals but also the majority of the water's natural mineral content.
Why Mineral Loss Isn't a Health Concern
Many people worry that drinking "pure" RO water will lead to mineral deficiencies. However, nutritional science suggests that water is not our primary source of minerals:
The "Food vs. Water" Perspective
- Bioavailability: Humans primarily absorb organic minerals through the food we eat. The inorganic minerals found in tap water are much harder for our bodies to process.
- Concentration: One cup of milk contains as much calcium as roughly 1,200 cups of mineral tap water. Similarly, a single orange provides significantly more nutrients than gallons of untreated water.
- The Verdict: True nutrition comes from a balanced diet, not the trace elements found in your plumbing.
The Best of Both: Remineralized RO Water
If you prefer the absolute purity of Reverse Osmosis but want the crisp taste and pH balance of mineral water, SimPure offers specialized Alkaline Remineralization systems. These filters strip away 99% of contaminants and then reintroduce essential minerals like calcium and magnesium back into the water at the final stage.
