1) With the first filter: PRE-CARBON which, with pores as small as 5 microns, removes all 32 identified organic contaminants such as THM, pesticides, nitrates, glyphosfates and the most common herbicides. The 5 micron pores can block micro and nano plastic particles. Many competing filtration systems have only this first stage of activated carbon as primary filtration, while here with us this is only the first barrier that stops the mass of contaminants. Therefore, this filter cartridge must be changed every six months. (You will therefore find 2 cartridges in the box!)

2) The second stage is an ULTRAFILTRATION MEMBRANE with minute pores of only 2 microns. This filter stops not only most harmful bacteria in the water, but virtually all fungus and algae spores that may be in it, as well as organic contaminants that are trapped here. This filter must be changed every 12 months.

3) The third stage is a filter system which is patented by a Korean company and lets us use the patent under license: The interaction of certain internal ceramic parts creates an electropositive field that traps and blocks microorganisms and viruses! Here, too, we have extremely small pores of only 2 microns in size which continue to trap the smallest elements and impurities and thus practically also act as a second ultrafiltration. The replacement interval for this cartridge is also 12 months.

4) The fourth stage is an activated carbon filter, but this time with a more compact structure and with pores as small as 2 microns! Thus, yet another insurmountable barrier is placed in the way of the smallest impurities. Here, all chlorine residues and other chemical components that may have passed through the first activated carbon filter are finally removed. In this stage, the taste of your water is also improved as all foreign and external chemical components are eliminated. So now you have the NATURAL taste of your water without vital minerals removed from it by too aggressive filtration! (As for example with excessive OSMOSE or REVERSE OSMOSE filtration where only H2O is produced without any minerals and moreover at least 3liter of water are wasted to create 1 liter of filtered water!!!). This filter cartridge only needs to be changed every 12 months.
