Frequently Asked Questions

Is a FEWATEC Cristal filter easy to connect?

The FEWATEC Cristal filter is delivered pre-assembled and ready for use. It can be mounted to an existing faucet within a few minutes using the two-way tap supplied with the supplied accessory. If you need additional adapters, contact us.

The installation of a table or wall model is a bit more involved. Here we recommend to have the installation carried out by a fitter.

How many liters of water can be purified by a FEWATEC Cristal filter?

With a FEWATEC Cristal filter cartridge 6-8000 liters of water can be cleaned. The filter capacity, however, depends on the load on the water, e.g. from the degree of hardness. If you give us information about the approximate degree of stress (hardness, etc.) of your water, we can tell you how many liters you can clean with a filter cartridge.

How do I know that the cartridge needs to be changed?

With a FEWATEC Cristal filter cartridge, 6-8,000 liters of water can be cleaned. The filter capacity, however, depends on the load on the water, e.g. from the degree of hardness.

This degree of hardness can be easily measured with our AQUASOFT TESTBAGS. A set of 5 test strips costs CHF 5.-

But even without tests it can be determined purely in taste that the quality of the water decreases, for example by an increased taste of chlorine.

We recommend replacing the cartridge with a 4-person household after 6 months. The more people, the higher the water consumption and the sooner the cartridge should be changed.

How can used filter cartridges be disposed of?

Please note the applicable waste regulations. If no waste regulations exist, you can dispose of the used cartridges with the normal household sweeper. Do not dispose of in the environment (littering).

How does the taste change with a FEWATEC Cristal filter?

The taste of the water can change positively. Thus, the filter removes e.g. the common taste of chlorine in many countries.

Can I also use the water from a FEWATEC Cristal filter for the preparation of coffee and tea?

The water ingredients affect the taste of your coffee or tea.
Odors in the water are removed by the filter (e.g., chlorine).
High water hardness, i. a high proportion of magnesium and calcium ions, react at higher temperatures, there is a turbidity and changes in the taste of the hot beverage. The filter removes these ions for the most part. But leaves so much in the water, which are necessary for the optimal tea or coffee enjoyment.
In addition, your machine calcifies less quickly due to the treated water.

Is the water from a FEWATEC Cristal filter hygienically flawless?

The triple system (activated carbon, silver and membrane filter) keeps pathogens back or has a disinfectant effect so that you can enjoy a hygienic, impeccable water.

Can I also use the water from a FEWATEC Cristal filter for watering flowers?

The ion exchanger used in the FEWATEC Cristal removes the magnesium and calcium ions responsible for the water hardness. The treated water becomes soft and therefore suitable for watering plants. If you only need the treated water as pouring water, we recommend Fewatec Rain.
