iFilters KDF and GAC City or Well Water Whole House Filtration 4.5" x 20"

KDF2-4520 4.5" x 20" Coconut GAC + 2LBS KDF Big Blue size cartridge. For City or Well Water Whole House or Commercial use.

This filter is made from coconut shell GAC in combination with KDF? media to significantly extend the life of the filter cartridges and provide exceptional filtration. KDF? 55 media is a redox media that removes chlorine, and reduces heavy metals. KDF? redox media is bacteriostatic and inhibits the growth of microorganisms in the filter.

The GAC Activated carbon has remarkable cleaning and absorptive properties, which makes it an effective way to purify water. Chemicals and contaminants in the water are absorbed by the carbon, effectively removing and reducing them from the water.

The addition of KDF? media is used to complement activated carbon filters. It aids in the removal of chlorine when treating municipal waters, and extends the life of carbon, while limiting bacterial growth in the filter. Additionally, the KDF? has the ability to remove water-soluble cations via the oxidation-reduction process, resulting in a cost effective alternative to chemical treatment.
