AQUAPHOR® Corporation manufactures AQUALEN® chelating cation-exchange fiber. AQUALEN® is specially developed to effectively remove heavy metal ions from water.
AQUALEN® contains carboxylic cation exchange and nitrogen-containing anion exchange groups. These groups form chelating centres, which selectively adsorb heavy metal ions .
AQUALEN® fibers are an order of magnitude thinner than the human hair. AQUALEN® shows superior speed of cation exchange toward heavy metal ions as compared to the state of the art granular resins. AQUALEN® can be easily regenerated.
AQUALEN® сan be effectively used for heavy metals (copper, lead, cadmium, et cetera) removal and polishing of rinse, waste and tap water and other fluids.
AQUAPHOR® filters comprise compressed matrices of the powdered coconut shell activated carbon, ion-exchange resins and AQUALEN® microfibers. Highly hydrophilic and bactericidal AQUALEN® fibers bind the matrix together and, at the same time, provide capillary flow permeability with the high flow and low pressure resistance. The resulting matrix has exceptional dirt holding capacity.

Size of the activated carbons particles which are used in the Aquaphor filters is several times smaller than the activated carbon particles in the traditional water filters.
It allows to increase the effective outer surface and speed of adsorption.
The gaps between the particles are filled with the ion-exchange fibers.

The main reason for superior performance of all AQUAPHOR® filters is AQUALEN® microfibers compressed with the powdered activated carbon and ion-exchange resins.
Bacteriostatic effect
Bacteriostatic testing of pitcher filters according to the NSF 42 method.
Patented bacteriostatic Aqualen® fibers comprise imbedded silver micro crystals and silver ions.
Silver migrates between Aqualen® fibers and the outer surface of the activated carbon particles.
Very small and constant concentra-tion of silver is present in the filtered water as a result.
