20" x 4-½" KDF-GAC Cartridge
* KDF water filtration media is a high-purity alloy of both copper and zinc and when used along with Granulated Activated Carbon which is good at reducing organic pollutants, algae, odours and bad taste a very effective filter is created.
* Small particles of carbon called carbon "fines" are present in a new KDF-GAC filter and should be generously flushed when first installed to wash away the carbon fines.
* Manufactured from FDA grade materials.
Suitable for all 20 inch Big Blue, Big White and Jumbo housings.
Always install the correct way up with the water flowing in through the KDF at the bottom.
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
