• Top-Notch Quality: Our FC25B CTO Carbon Block filters are made of high-quality coconut shell activated carbon for maximum filtration efficiency and filter life. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. This whole house water filter is tested by an independent third-party to meet NSF/ANSI standards.

• Please Note: The water filter cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
