CTO Carbon Water Filter Cartridge

High quality activated carbon used in this carbon water filter cartridge has an excellent adsorption effect to free Chlorine, odor as well as filter out organic compounds. Moreover, coconut shell carbon water filter cartridges remove THM’s and some other Chemical substances better. CTO carbon water filters have small water flow rate and long filtration life compared with GAC cartridges.


GAC Carbon Water Filter Cartridge

Using NSF certified granular activated carbon as raw materials, GAC carbon water filter cartridges is good at removing objectionable tastes, Chlorine, unpleasant odor, lead and microorganisms. The carbon the filter cartridge used has been processed by acid-washing and wind-selection and end caps of this carbon water filter cartridges are fixed with special PP layer instead of general non-woven cloth. No carbon fines releasing from the filter cartridge while keeps a high water flow rate as the same time.
