1. How to properly choose a water filter?
Anyone who decides to purchase a water filter inevitably faces the problem of choice – what filter should be bought? Should it be one with an attractive design, or one commonly advertised by foreign or domestic manufacturers, with its own tap, a filtration jug, or a filter recommended by a neighbor? Of course, we value your neighbor’s opinion, but you are choosing a filter for yourself, so try to focus on your own needs and the seller’s recommendations, or simply contact us and we will help you with a tailored solution.

2. Why does tap water have a bad taste and odor?
The taste and odor of tap water are caused, among other factors, by the presence of chlorine. In addition, chlorinated organic substances (formed when chlorine reacts with organic matter in the water) can intensify the unpleasant smell. Unfortunately, there is no alternative standard method of disinfection.

3. Is chlorine dangerous?
In accordance with hygienic standards, the concentration of chlorine present in tap water is not dangerous to healthy individuals. The role of chlorine is to kill all living organisms in the water (viruses and bacteria). Among other things, it was used as a chemical warfare agent during wars. Unfortunately, when drinking chlorinated water, this also affects our beneficial bacteria in the stomach and intestines. In individuals with asthma or allergies, even a small concentration of active chlorine may worsen their condition. Moreover, chlorine reacts with organic substances in tap water and causes the formation of chlorinated organic compounds (e.g. chloroform, chlorophenol, and dioxin).

4. Is rainwater healthy?
The atmospheric air is largely heavily polluted with various man-made substances (nitrogen and sulfur oxides, organic compounds, radioactive dust). All these substances fall to the ground in the form of "acid rain". Anything acidic only further increases the body's acidity, resulting in a weakened immune system.

5. Can poor quality water be improved by boiling?
Boiling water can destroy bacteria and reduce the concentration of volatile organic compounds (VOCs), but the concentration of non-volatile and inorganic substances will increase because pure water evaporates and thus the concentration of undesirable substances rises.

6. Can a filter release some undesirable substances back into the water?
AQUA water filters are made of high-quality materials (virgin pure plastic) used where the highest purity is required for contact with water. These materials are, for example, used in the manufacture of children's toys, baby bottles, in medicine, and wherever maximum material purity is demanded.

7. Can I store filtered water?
For storage until the following day, it is recommended to keep filtered water in the refrigerator. Since filtered water is very pure and free of viruses and bacteria, it can be stored for a very long time without any signs of off-taste.

8. And what about bottled water?
Both imported and domestic bottled water is usually produced by purifying ordinary tap water (except for mineral water from natural sources). The purification process is predominantly based on carbon filters that remove undesirable tastes and odors. Everything else, however, remains.

9. Why does clear, transparent water from artesian wells quickly become cloudy and yellow?
Artesian water, when coming into contact with a clayey substratum, is typically enriched with mineral salts containing aluminum, iron, and ions that cause water hardness. The concentration of iron can reach up to 30 mg/l. Once the water is exposed to oxygen, the dissolved iron ions oxidize and convert into insoluble ferric oxide, which precipitates and gives the water a rusty color.

10. What is a pre-filter?
A pre-filter is the first barrier against impurities in the water. It removes solid sediments such as rust, mud, sludge, sand grains, etc., thereby extending the lifespan of the much more expensive main filtration system, which is usually a carbon filter and an RO membrane. Impurities can consist of particles of various sizes: from large sand grains to submicron colloids. The fineness of the pre-filter "mesh" depends on the material from which it is made and its design.

11. What does a carbon filter do?
A carbon filter binds chlorine and its compounds, as well as certain chemicals. It removes undesirable taste and odor from the water, making it clearer. However, its function ends there. Carbon cannot remove nitrates and nitrites, heavy metals, or a range of chemical substances. While it is often used as a simple filtration method for tap water, it is frequently insufficient for lower-quality water.

12. Which adsorption materials are used in AQUA filters?
AQUA systems use only high-quality materials intended for food contact: ion-exchange resins for water softening, high-quality granular activated carbon from coconut shells or pressed into "Carbonblock". As the main sorbent, AQUA uses COMPOSITES FROM ACTIVATED CARBON (ACC) – a matrix consisting of activated fiber and granular activated carbon (GAC), which provides excellent sorption performance and capacity against harmful organic and inorganic compounds (chlorine, chloroform, phenols, pesticides, copper, mercury, etc.) along with an excellent ability to retain impurities.

13. Is water treated by reverse osmosis suitable for drinking?
Membrane filtration is one of the most effective filtration methods in the world. Its efficiency is around 90% for domestic filters and up to 99.7% for industrial filtration. Thus, water after this filtration is very pure but has a low pH. Such water is not suitable for drinking because it is "hungry" – it quickly binds other substances and minerals. After RO membrane filtration, reverse remineralization is always necessary to restore the essential minerals in the water. Unfortunately, most companies have very inefficient remineralization – there is not enough remineralizing mix of the required quality, or there is insufficient time for the water, flowing at about 4l/h through the remineralization system, to reabsorb mineral ions (predominantly calcium and magnesium). The AQUA filtration system uses its own specially developed remineralization mix, which has a high capacity to release minerals back into the water. The water passes directly after the RO membrane through this remineralization mix, ensuring the ideal ratio and quantity of minerals for the human body and significantly increasing the pH of the filtered water. This results in AQUA water effectively regulating the body's acidity and returning it to neutral levels, while retaining its detoxifying properties. Consequently, it markedly improves the immune system, reduces illness and inflammation (as viruses and bacteria multiply much faster in an acidic environment), and enhances overall health, energy, and mood.
