iSpring F2WGB22BPB Universal Whole House Water Filter Set Whole House Replacement Filter

The first stage is a 5-micron CTO coconut shell carbon block filter. 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 chlorine from the water, and is highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals. The second stage of the WGB22B-PB houses an iron and lead reducing filter. The FCRC25B iron and lead reducing filter is only included with the WGB22B-PB (and the WGB32B-PB), as it is not needed for most municipal water supplies that the WGB22B targets.
