FAQ

Does a filter help against hard water and limescale?

Yes, if you choose the right system. When water is particularly hard, simply improving its taste isn't enough: you need a solution designed to reduce hardness and limit limescale buildup. In these cases, under-sink systems and reverse osmosis are often the most effective and convenient options. If the problem is limescale, chlorine odor, rust, or other impurities, you can learn more in the "Solutions" section.

Which system should you choose: carafe, faucet filter, under-sink system, or reverse osmosis?

The choice depends on water quality, daily habits, and desired level of comfort. For basic needs, a filter jug ​​may suffice. For more practical and continuous use, an under-sink system is often the ideal solution. When deeper filtration is desired, especially in hard water, reverse osmosis is often the most comprehensive option. To help you find your way around, you can start with our "Solutions" section.

Why use a filter if the tap water is already drinkable?

Because potable water doesn't necessarily mean pleasant water to drink every day. In many homes, water can have a chlorine smell, an unbalanced taste, or be unsuitable for tea, coffee, and cooking. A quality filtration system helps enhance it, making it more pleasant, more balanced, and better suited to daily well-being.

Why do some systems reduce hardness and others add magnesium?

Because the key isn't to eliminate minerals altogether, but to achieve the right balance. Hard water contains excess salts that promote limescale buildup and can alter taste. Some systems eliminate the excess, while others, after filtration, enrich the water with selected minerals in balanced quantities, achieving a more pleasant and harmonious profile.

How is AQUAPHOR different from conventional filters?

AQUAPHOR goes beyond the concept of a standard filter. Our systems combine advanced filtration technologies, proprietary materials, and solutions designed to deliver high performance, long-term stability, and a superior user experience. The result is water with a finer taste, greater reliability, and quality you can experience every day.

Is it true that magnesium improves the taste of water and coffee?

Yes, water well-balanced with magnesium can be smoother and better enhance the aromatic notes of tea and coffee. For this reason, some AQUAPHOR solutions are designed not only to filter water, but also to improve its organoleptic profile. To learn more about the role of magnesium and its importance for coffee, visit our dedicated coffee section.

Does a filter help against hard water and limescale?

No, many AQUAPHOR systems are designed for simple and straightforward installation. Some models are ready to use, while others only require a basic connection under the sink. In many cases, you can even do the installation yourself. To make everything easier, we provide clear instructions and video guides, even for the most comprehensive systems.
