This cartridge (Patent No. 2287356 dd. 30.06.2015) combines several water treatment methods: mechanical; ion exchange, adsorption; electric adsorption.

Polymers with a space globular structure (SGS-polymers) were first synthesized in the USSR as the type of ion-exchange resins in the middle of 20th century.

Today only Geyser has a serial production technology of this material. SGS-polymers are radically new material combining three types of filtration: mechanical, absorption, and ion-change filtration. No known absorption materials can remove such a wide range of chemical compounds like SGS-polymers do.
