Reverse Osmosis Systems are among the most accurate devices for water filtration. Water filtration through an RO systemconsists in the separation of water molecules from other compounds dissolved therein, through a semi-permeable membrane – this is the reverse process of the natural process of osmosis occurring in all living cells. Osmotic membrane retains 96% - 99% of organic and inorganic pollutants soluble in water, bacteria, and various viruses.

The semi-permeable RO membrane consists of multiple layers wound on a perforated pin arranged inside the membrane. Contaminated water is forced under pressure over the membrane surface, where the water molecules pass through the microscopic pores of the membrane. Impurities are separated and discarded to drain. Within the range of SUPREME products you will find six-, seven-, even eight- step systems.

Small Filter sets for all RO models (RO-6, RO-7, RO-8 Premium) need to be changed every 6 months.

Larger filter sets are meant to be changed every 12 months.

The Pentair Osmotic Membranes need to be changed every 3 to 5 years, depending on the quality of the raw water.

You can find the changeable filter sets here.

Absolutely! The components are American NSF certified, and meant for everyone, including infants, children and pregnant women.

Absolutely!

This is exactly what the RO filters are meant for. The filtering system will remove mud, sand, suspensions, chlorines, organic coumpounds, heavy metals, pesticides and water hardness

Furthermore, RO systems are designed to enrich water with minerals that are essential for health, as well as it corrects the mineral composition of water, ph and its organoleptic properties.

Osmotic filtration allows to remove compounds that are responsible for the unpleasant taste and aroma of water. The final filtration step is performed on a linear cartridge filled the highest quality activated carbon. After passing through the carbon bed, the water achieves excellent taste and aroma.

A linear S-L-CARB carbon cartridge, improving the taste and aroma of water, is installed in all the models of the RO systems by SUPREME.

Mineralised water can be used for plant watering, as the correction of PH and minerals are great for everyone and everything - people, animals, plants.

Osmotic filtration removes most of the impurities from the water. The filtration process removes such minerals as: calcium and magnesium.

In some RO system models, a mineralising cartridge is installed at the end of the filtration process. After passing through the mineraliser, water is enriched with mineral elements such as calcium and magnesium. The concentration of minerals in water is comparable to the concentration of bottled mineral water

* a linear S-L-MIN mineralising cartridge is installed in the all systems:
SUPREME RO-6, SUPREME RO-7, SUPREME RO-8

Ionisation of water through the S-L-FIR cartridge, consists in reducing its clusters, so that the body is rapidly hydrated and toxins are rapidly removed.

Ionised water is also a natural antioxidant that effectively sweeps away free radicals responsible for the rapid ageing of our body and responsible for the formation of cancerous diseases. Ionised alkaline water neutralises the acidity of the body (adjusts the pH).

* a linear AIFIR2000 ionising cartridge is installed in the SUPREME RO-7 system & SUPREME RO-8 Premium system

Yes! You can drink water subjected
to osmotic filtration without prior boiling.

No! All the systems of the SUPREME brand have a valid attestation of the Polish National Institute of Hygiene (PZH), which allows the systems to have contact with water.

Yes! Apart from contaminants, the RO system also removes mineral salts from the water.

The SUPREME-RO7 and SUPREME-RO8 PREMIUM systems are equipped with a mineralising cartridge which secondarily enriches water with minerals essential for the human body
