The filter Ecosoft FU 1665 CE Twin is designed to reduce the hardness of household water. The system consists of two main components - a module (a cylinder with a control valve) and a salt solvent tank.

What is hard water?

Sediments on the heating elements of household appliances, white bloom on tiles and plumbing, stains on glass surfaces are the results of hard water using.
In addition to the destructive impact on the state of household appliances, a high content of hardness ions has an impact on human health. This problem is inherent both for water from natural sources, and for the city water supply. The reasons for this can be hard source water, the imperfection of centralized water purifuing, as well as the use of outdated technologies.

Effective solution for the problem of hard water

To reduce the hardness of household water, softening filters are used. Ion-exchange resin HCR-S/S (cation exchange resin manufactured by Dow, Dowex™) is used as filter media. During the filtration process, an ion-exchange reaction takes place -  the ions of hardness salts are replaced by safe sodium ions, that provides normal level of water hardness.
Filter softener reduces energy consumption, increases the efficiency of household appliances and reduces the frequency of breakdowns, significantly reducing the cost of repairs.

Filter features

  • Economical consumption of salt tablets.

  • The filter is fully automated, silent.

  • Attractive and compact design.

  • Reliable and efficient operation for at least 5 years.

*Subject to proper operation and timely replacement of filter media.

Filter device

  • Cylinder (column) with filter media.

  • Salt-solvent tank with a capacity for tableted salt storage and salt solution for the regeneration of filter media prepare.

  • Control valve (installed at the top of the column).

  • The filter vessel is made of a anticorrosive composite polymer material.

Who are the users?

The Ecosoft FU 1665 CE Twin filter is designed for houses and apartments with 5-6 bathrooms. It is intended for softening of water of a household purposes.
The system is designed for daily water preparation for 9-10 people. After softening, water can undergo an after-treatment to a drinking quality using a reverse osmosis system.

The filter is connected to the cold water supply system, effectively purifies the water and independently controls all the processes of its work.
Pre-purified from mechanical impurities water enters the filter vessel filled with Ecomix® filter media. The media consists of five components that successively trap iron, manganese, organic impurities and hardness salts. Purified water through the central pipe of the case is supplied to the consumer.


When the resource of the filter media ends, the filter independently goes on regeneration, but only at a time when water consumption is minimal, so it won't deprive you of access to purified water. In addition, the control valve remembers the intensity of your water consumption at different times and is adapted so that clean water is available even at peak consumption, for example, on weekends.

Regeneration takes place in 5 stages

  • Flushing back flow of water. At the same time, iron and manganese compounds are washed out of the filter media.

  • A solution of salt is fed from the tank into the filter vessel, passes through the Ecomix® and washes away hardness salts and organic matter from it. Impurities with the remnants of the solution are discharged into the sewage.

  • Short backflush. Once again, loosens the load and washes away the remnants of the salt solution.

  • Flush the Ecomix® with a direct stream of water to lay layers of media in the desired order.

  • Fill the salt tank with water to dissolve the tableted salt and prepare the solution for the next regeneration.

After that, the system can purify water again.

Thanks to the use of a multifunctional valve, the filter does not require constant attention.

The only important task connected to maintenance for customer is timely stocking of the salt. It will ensure efficient regeneration of the filter media and thus durable filter service life and water quality. 

If any problem arises, the valve will inform about the problem at the display with a text message.
