This is the only approved replacement filter for AlkaMedi-3000S water ionizer. It's a high-quality compound carbon block filter.
These filters are carbon block filters, supplemented by a calcium layer for extra power in chlorine removal. Carbon block is better than loose carbon media, because it forces the water through. It filters out common municipal contaminants, such as chlorine and its byproducts. Also heavy metals and other common contaminants.
