How the water filtration system works

Water in this system flows through 3 replaceable filter cartridges. Each cartridge performs a specific function, and together they create an effective multi-stage purification system for kitchen use.

Stage 1: K5 cartridge

A replaceable filter cartridge made of 100% polypropylene. It is used as a pre-filter to retain mechanical impurities such as sand and rust. It protects the further filtration stages. Removes impurities down to 5 microns.

Stage 2: K2 cartridge

A replaceable filter cartridge made using carbon block technology with Aqualen fiber and activated coconut shell carbon. It effectively removes organic compounds and active chlorine from the water. Removes impurities down to 3 microns. The ion-exchange Aqualen fiber together with modified selective chelating compounds deeply and effectively removes heavy metals from water. Contains safe silver in an active ionic form.

Stage 3: K7 cartridge

Made using carbon block technology with fiber and activated coconut shell carbon. Used as the final stage of purification for drinking water. Effectively removes all organic compounds and heavy metals from water. Removes impurities down to 0.8 microns. The modified ion-exchange Aqualen fiber distributes the water stream across the entire filtration surface, enabling the highest filtration quality. Contains safe silver in an active ionic form.

This configured filtration system helps improve the organoleptic parameters of water, reduce the presence of mechanical impurities, and support everyday comfort when using drinking and utility water in the kitchen.

Click & Turn technology

Thanks to Click & Turn technology, replacing the cartridges in the filter is very easy. To replace a cartridge, simply press the safety button (1) and then unscrew the cartridge (2). No tools are required.
