alloy) and GAC (granular activated carbon), providing superior filtration qualities.
Through the electrolytic and oxidation reactions of the KDF and the adsorption and
entrapment capabilities of the GAC, the KDF/GAC can remove or greatly reduce a
wide range of contaminants through to 30,000 litres.
The KDF media also provides a bacteriostatic effect which is hostile to algae, fungi
and bacteria.
The OKDF30/1 is also Cyst safe.
