The Pro HF cartridge consists of two parts: dense hollow fiber membrane and fine sorption section.

The hollow fiber technology ensures filtration of microparticles larger than 0.1 microns, providing reliable protection against chlorine-resistant bacteria that may appear in tap water. It represents a mechanical barrier with micropores, so the water filtration system cuts off bacteria and cysts without the use of chemical bactericides.

The sorption part of the cartridge provides fine filtration that removes dissolved contaminants: active chlorine, heavy metals, organic substances and other trace of toxins and allergens.
