The truth about pure water

Reverse osmosis and microfiltration are two popular methods for purifying water, but there's often misinformation about their effects on water quality. Here's a clear distinction between the two.


It's claimed that reverse osmosis, a water treatment system, also removes essential minerals, making the water similar to "distilled" water. This claim, often propagated by competitors or mineral water producers, is actually a false myth. AQUALUX systems, for example, offer precise regulation of the salinity of treated water, ensuring an ideal balance.


It's essential to understand that water is not a primary source of minerals for our body. The minerals in water are inorganic and, therefore, not easily assimilated by our system. In contrast, organic minerals, found in foods like milk and its derivatives, are those that our body can utilize.

The importance of oligomineral water

Oligomineral waters (like those from mountain springs), with low fixed residue and few inorganic minerals, are considered the best for the body. These waters are light, pollutant-free, and have high hydrating and purifying power.

The right choice

Water produced by a high-quality reverse osmosis system, like those offered by AQUALUX, mirrors the ideal characteristics of healthy and pure water, suitable for daily consumption.


Microfiltration: A Basic Filtration

Microfiltration is a mechanical process that physically separates impurities from water, such as sand, rust and limescale particles. Its filtering capacity is measured in microns. Many filters contain activated carbon, which is useful for absorbing chemicals such as chlorine. However, it is essential to note that many products marketed as "purifiers" are actually microfiltration systems. These do not eliminate dissolved substances such as limestone, nitrates and heavy metals, which are among the pollutants most harmful to health.


Reverse Osmosis: The True Purification

In AQUALUX purifiers, microfiltration acts as a pre-treatment, while osmotic membranes are responsible for the actual purification. These membranes have a filtering capacity up to 10,000 times greater than microfilters.

To understand the difference between microfiltration and reverse osmosis, a conductivity meter can be used. This instrument measures the electrical conductivity of water, indicating the presence of foreign substances. Values between 50 and 120 microsiemens indicate pure water, while higher values (from 300-400) suggest heavy and calcareous water.


Boiling is a simple but revealing method for evaluating the purity of water. By comparing three saucepans on the stove - one with tap water, one with microfiltered water and one with water purified through reverse osmosis - the results will be surprising after just a few minutes.


Do you notice the difference?

Reverse Osmosis

Pure water, obtained through reverse osmosis, not only protects our health but also improves the taste and aroma of dishes. Whether it's cooking or preparing a simple herbal tea, pure water enhances the flavor and aroma, offering a superior and healthier culinary experience.
