Three stages of water filtration

Stage 1: FCPS5 - 5-micron mechanical filtration
In the first stage, the FCPS5 sediment cartridge made of polypropylene foam works. Its task is to retain mechanical impurities up to 5 microns in size.
captures sand, silt, rust, and other solid particles present in the water,
helps protect the home installation and appliances from damage caused by mechanical impurities,
forms the basis of effective multistage filtration and prepares the water for further treatment.
This is the stage responsible for the basic cleanliness of the water and for protecting the next filter cartridges in the system.
Stage 2: FCCST2 - water softening and reduction of iron and hydrogen sulfide
The second filtration stage is the FCCST2 cartridge, whose task is to treat the water by reducing hardness and lowering the concentration of iron and hydrogen sulfide.
helps limit the effects of hard water,
supports the protection of appliances and fixtures against limescale buildup,
improves the comfort of everyday use of water in the kitchen.
This is a practical solution for households that want better utility parameters of water and protection of equipment against deposits.

Stage 3: FCCBKDF - carbon filtration with KDF
The final stage is responsible for the final cleaning of the water and improving its utility properties. The FCCBKDF cartridge removes chlorine, pesticides, heavy metals, and organic contaminants, while also improving the taste and smell of water.
reduces undesirable compounds affecting taste and aroma,
helps limit the presence of selected chemical contaminants,
combines the action of activated carbon and a KDF bed.
Activated carbon and the KDF bed work together to effectively neutralize potential threats and provide bacteriostatic properties. As a result, the water becomes more pleasant in everyday use, especially for drinking and preparing beverages.
