Protect your home from limescale with a water softener. Discover how these systems improve energy efficiency, extend the life of your appliances, and care for your skin and hair. Explore ATH water softener options and choose the perfect model for your needs.

Hard water is a common problem in many households, especially in areas with high levels of lime in the water. Limescale buildup can damage appliances, reduce the efficiency of heating systems, and lead to unnecessary expenses in maintenance and energy consumption. The most effective solution to combat this problem is to install a domestic water softener, a system designed to remove the minerals responsible for water hardness, such as calcium and magnesium.

In this guide, we explain why it is important to install a water softener, the differences between the main types of systems, and how to choose the most suitable model according to your household needs. In addition, we recommend three options of high-performance ATH water softeners:

ATH Robosoft 120e (20 liters)
ATH Robosoft 180e (26 liters)
ATH Compact 700/030V (30 liters)

Why install a water softener at home?

A water softener provides multiple benefits in the home, improving both water quality and the lifespan of appliances and pipes. Its main advantages include:

Limescale protection: prevents the accumulation of limescale deposits in pipes, faucets, showers, and appliances such as washing machines, boilers, and water heaters.
Energy savings: less limescale allows heating and hot water systems to operate more efficiently, reducing energy consumption.
Longer lifespan for appliances: washing machines, dishwashers, and water heaters last longer without breakdowns caused by limescale buildup.
Softer, spotless laundry and dishes: softened water improves detergent effectiveness, reduces detergent usage, and eliminates residues on clothing and glassware.
Healthier skin and hair: soft water is less harsh on skin and hair, reducing dryness and irritation.

Types of water softeners: with or without salt?

When choosing a water softener, it is important to know the main technologies available on the market:

Salt-based water softeners (ion exchange) – These are the most effective at removing limescale from water. They work by exchanging calcium and magnesium ions for sodium ions, preventing scale buildup. They are ideal for households with medium or high water consumption.
Salt-free water softeners – These use physical or chemical systems to modify the structure of minerals without removing them. They do not reduce water hardness, but they prevent limescale from adhering to surfaces. They are a suitable option for those who wish to avoid using salt, but their effectiveness may be lower.

Which water softener to choose according to household consumption?

The size of the water softener is a key factor in choosing the right model. To size it correctly, it is necessary to know the water hardness and the household's daily consumption. Below, we present three ATH water softener options ideal for different needs:
