This replacement filter pack comes standard with two 5-micron high-capacity polypropylene sediment filters. This filter removes dirt and other various larger-sized particles from the water that can clog the following filters. It also comes with two 5-micron CTO coconut shell carbon block filters. Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of sediment and chlorine from the water, and is highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals.
