The newly designed filters incorporate an innovative powder activated carbon infused filter media, which is pleated around a carbon block center core. This foul-resistant filter allows the carbon block to more fully utilize its total chlorine adsorption capacity as the media helps to prevent foulants from reaching the carbon block surface. Applications for these carbon-based filter cartridges include drinking water for residential and commercial use, and in process and wastewater applications for industry. These filters are capable of removing a wide range of soluble and insoluble contaminants as compared to most water filter systems where the sediment and activated carbon stages are separate and often require separate housings. The filters are highly efficient for removing chlorine, bromine, and iodine; and should also prove to be efficient with other contaminants known to be removed by carbon such as TOC’s, halogenated organics, endocrine disruptors and other soluble toxic substances, according to the manufacturer. This is in addition to proven effectiveness at removing pathogenic microbes, turbidity, color and odor.
