Stage 1: Polypropylene filter that reduces dirt, sediment, and rust. Protects the next stages of water filtration.

Stage 2: Primato ULTRA CTO compact activated carbon filter with 5 micron permeability. Reduces chlorine, chloroform, unpleasant taste, odor, suspended particles, sand, rust, sediment, total organic carbon, industrial organic compounds (tetrachloroethylene, trichloroethylene), dissolved organic compounds, organic color, dissolved iron, manganese.

Stage 3: Primato ULTRA PB compact activated carbon filter with 0.5 micron permeability. Effectively reduces chlorine, unpleasant taste and odor, heavy metals, chloroform, pesticides, organic chemicals, volatile organic compounds (VOCs), industrial residues, toxins, turbidity, cysts, Cryptosporidium, Giardia, Toxoplasma, bacteria, microorganisms, asbestos fibers, suspended particles, mud, rust, sediment, and various other harmful substances for the body.

Also reduces lead, cysts, and heavy metals.

Stage 4: The fourth stage includes the installation of the reverse osmosis membrane, which is not included in this set. The membrane needs to be replaced every 2 years.

Stage 5: In the fifth stage, the water is enriched with minerals. The water, after enrichment, has ideal proportions of minerals necessary for the healthy development of the human body.

It adds the following:

Cations

• Calcium-34mg/L. Calcium is a vital element for bones and teeth. It regulates the heart and arteries and aids in proper digestion of food.
• Magnesium-12mg/L. Magnesium participates in 300 different biochemical processes in the human body. It helps the immune system and proper blood circulation.
• Sodium-22mg/L. Sodium regulates the proper absorption of water by our body.
• Potassium-8.5mg/L. It acts as an electrolyte and is required for maintaining the good condition of the heart, brain, kidneys, muscle tissue, and other important organ systems of our body. It works with sodium to perform certain critical body functions.

Anions

• Carbonate salt CO32-: 10mg/l. Its presence in our body is particularly important as it regulates the acidic environment.
• Sulfate salt SO42-: 0.3mg/l. Sulfate salt contributes to the absorption of nutrients, helps in dealing with migraines, and aids in the elimination of toxins.
• Chloride Cl-: 0.8mg/l. It is an essential electrolyte found in all body fluids responsible for maintaining the acid/base balance, transmission of nerve impulses, and regulation of fluid inside and outside cells.
• Fluoride F-: 0.06mg/l. Fluoride helps prevent tooth decay.

Stage 6: The water passes through the coconut shell activated carbon filter Primato Inline. This filter provides a final "refinement" to the stagnant water in the tank. Since the water produced by reverse osmosis is relatively tasteless, this filter corrects these imperfections so that you can enjoy your water better.
