The set includes four modules: K5, K2, K7M, membrane module K-50S.
K5 - Pre-cleaning. Filters out rust, sand and other undissolved particles larger than 5 microns. Protects the membrane further downstream of the water
K2 - Deep filtration. Carbon module (carbfiber block) - absorbs chlorine and other dissolved impurities from water, removes heavy metals from water. Filters particles as small as 3 microns. Protects the membrane further downstream of the water.
K-50S - reverse osmosis membrane, top drainage.
K7M (post-filtration and mineralization). Enriches the water with minerals and restores the pH of the water to a neutral value.
