The Granular activated big post carbon filter is made of high-quality coconut shell activated carbon or nutshell activated carbon, therefore, it does not need any binding agent, and it directly fills the plastic housing. This kind of filter has a good seal performance and a large flow rate. Sintering activated carbon T33 filter uses nontoxic and tasteless efficient coconut shell activated carbon and coal activated carbon as the main body, supplemented by food grade adhesive material, after special craft processing molding, makes the filter both have adsorption effect and filtration effect.

Big Post Carbon Filter – Final Polishing Stage for RO Water

The big post-carbon filter enhances the quality of water produced by domestic reverse osmosis (RO) systems rated 300, 400, or 800 GPD. It removes lingering tastes, odors, and residual chlorine after the RO membrane, producing fresh and smooth drinking water. Because it acts as the final stage, it ensures every glass tastes clean and pure.

How It Works

Water flows through the big post-carbon filter after passing the RO membrane. The granular activated carbon (GAC) inside adsorbs organic compounds and residual chlorine. As a result, the water becomes odor-free and tastes naturally clean. The filter’s high-quality carbon maintains a consistent flow, while its large size accommodates higher-capacity RO systems efficiently.

Installation & Maintenance

Install the cartridge in the post-carbon housing as the final stage of your RO system. Flush with water before first use to remove loose carbon particles.
