Stage 1: Polypropylene filter that reduces dirt, sediment, and rust. Protects the subsequent 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, sediment, rust, soil, and various other harmful substances for the body. It also reduces lead, cysts, and heavy metals.

Stage 4: The fourth stage consists of the reverse osmosis membrane. The membrane has a permeability of 0.0001 microns and produces 50GPD (Gallons Per Day), which is equivalent to 189 liters per day. It filters salts, nitrates, chromium, arsenic, toxins, bacteria, and microorganisms. The membrane is NSF 58 certified.

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. Adding the following:

Cations

• Calcium-34mg/L. Calcium is an essential 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, muscular tissue, and other important organ systems of the body. It works with sodium to perform certain critical functions of the body.

Anions

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

Stage 6: The water passes through the Primato Inline coconut shell activated carbon filter. This filter provides a final "refinement" to the stagnant water in the tank.
