  Product Description

10"*2.5 KDF Refillable Filter Cartridge

Product Introduction

refillable carbon water filter

KDF media acts as a catalyst to change soluble iron (ferrous) cations into insoluble ferric hydroxide which becomes trapped in the filter. 

The hydrogen sulfide is converted into an insoluble sulfide precipitate which is then similarly trapped and filtered. Ferric iron is removed by mechnical filtration.

Pretreatment of water with KDF is a simple, low cost method. It protects expensive and fragile water treatment components from chlorine, microorganisms, and scaling. 

Compared to microfiltration, ultrafiltration, reverse osmosis membranes, ion exchange resins, and granular activated carbon, KDF offers more advantages in terms of improved water treatment efficiency and continued high efficiency with lower consumption. 

Today, KDF is used internationally in a wide range of applications from kitchen faucets to industrial cooling water treatment.
