FITaqua AC-IL-MIN is a linear mineralizer for reverse osmosis systems, designed for drinking water. It contains natural dolomite deposits with low sodium content, which enhance the taste of water and supplement it with calcium and magnesium, among other minerals. A Polish product, certified by NIZP PZH. Installed as the final stage of treatment in the RO system.
AC-IL-MIN FITaqua is an inline mineralizer designed for installations such as a reverse osmosis system, RO filter, and reverse osmosis filter. Installed as the final treatment stage, it enriches water after the RO process with natural minerals, including calcium and magnesium, improves the taste of the water, and supports daily water mineralization for drinking and meal preparation. It is a Polish product for drinking water, based on natural dolomite deposits with low sodium content, certified by NIZP PZH.

FITaqua AC-IL-MIN was developed as a professional inline cartridge for drinking water, typically used in reverse osmosis installations. In practice, this means that the cartridge operates where water has already been thoroughly purified by an RO membrane and then requires re-enrichment with selected micro- and macroelements.
The cartridge uses natural dolomite deposits with low sodium content. Thanks to the linear water flow, the mineralizer saturates the water with mineral components that not only improve its taste perception, but also provide a more natural profile for water used every day for drinking and cooking.
In systems such as reverse osmosis, the water filter removes a very broad spectrum of contaminants from the water. The final mineralizer is therefore an important stage of the entire process, because it enriches the treated water with natural minerals and improves its everyday usability.
The inline mineralizing filter performs an important function not only because of the expected taste of the water. Mineralization is also desirable for people who want to use water with a composition closer to high-quality mineral waters. Water previously purified by a reverse osmosis filter, after passing through the mineralizer, can also transfer the beneficial mineral compounds it contains to dishes prepared with it.
One of the most important features of the AC-IL-MIN FITaqua model is the use of natural dolomite-based mineralizing deposits. A properly selected deposit composition is important for the final composition of the water and for maintaining the recommended proportions of mineral saturation.
The cartridge adds the following components on average to each liter of water flowing through it:
This mineralization profile makes the water after filtration more pleasant in taste and better suited to everyday use at home.
Mineralizers in reverse osmosis systems are installed at the final treatment stages. AC-IL-MIN FITaqua works as the last stage of water production or, in systems equipped with a bioresonator, before bioceramic filters.
Thanks to this, the cartridge can be easily integrated into a typical RO water filtration system as the component responsible for final mineralization and taste improvement.
Important: the cartridge is intended for installation as the final treatment stage in a reverse osmosis system. Service life depends on the quality of the filtered water and its degree of contamination. The cartridge should be replaced at least once a year.
FITaqua solutions are optimized for Polish water conditions and comply with applicable standards in Poland for drinking water treatment. The cartridge is especially recommended for households using RO filters, including those where the installation is used by families with small children, elderly people, and people engaged in intensive physical or mental work.
To maintain stable mineralization quality, the cartridge should be replaced regularly. Typical service life is about 6–12 months, although the actual operating period depends on the quality of the water supplied to the system and its degree of contamination.
Even with less intensive use, the period of one year of operation should not be exceeded. Regular cartridge replacement helps maintain the expected water taste, the proper level of mineralization, and the correct operation of the entire treatment system.

It is an inline mineralizer used in reverse osmosis systems. Its function is to enrich previously purified water with natural minerals, mainly calcium and magnesium, and to improve the taste of water intended for drinking.
Yes, the cartridge is typically intended for RO installations, meaning where an RO filter or a complete reverse osmosis system is used.
AC-IL-MIN is installed at the final treatment stages. It can operate as the last stage of water production or, in selected systems with a bioresonator, before bioceramic filters.
To each liter of flowing water, the cartridge adds on average: calcium approx. 26 mg, magnesium approx. 20 mg, sodium approx. 1 mg, potassium approx. 0.5–1 mg, as well as anions: carbonates approx. 25 mg, bicarbonates approx. 30 mg, sulfates approx. 10 mg, and chlorides approx. 5 mg.
The recommended service life is about 6–12 months. The cartridge should be replaced at least once a year, and in practice the replacement frequency depends on the quality of the filtered water and its degree of contamination.
Yes, this is one of its most important functions. Mineralization of water after osmosis improves its taste and makes the water more pleasant for many users in everyday drinking and cooking.
Yes, the mineralizer uses natural dolomite deposits with low sodium content. The average amount of sodium added to one liter of water is about 1 mg.
The cartridge has a diameter of 52 mm and a length of 245 mm. It operates at water pressure up to 6 bar, at temperatures from 2 to 45°C, and its internal thread size is 0.25 inch.
Yes, it is a Polish product intended for drinking water, with NIZP PZH certification.
