Features
High capacity
Our FC25 CTO Carbon Block filters have a capacity of 30,000 gallons of water, enough to supply a family of four with clean water for half a year.
Why iSpring
At iSpring, we look beyond technology to make high-quality drinking water accessible for all households. We provide our customers with professional water solutions to any water concerns you may have.
High rejection rate
The FC25 carbon block filters are made of high-quality coconut shell carbon and are specially designed to remove up to 99% of chlorine from water as well as various other contaminants that cause unpleasant odors and tastes.
Clean Water For the Ones You Love
Save on your water bill - the filters won’t produce any wastewater.
The filters are specially designed for a high water flow: up to 12 gallons per minute.
Fits standard 20” x 2.5” filter housings, including iSpring WCB32C & WCB32O 3-Stage Whole House Water Filtration Systems, RCB3P Reverse Osmosis System, and products of other brands.
Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keep healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
If you have any problems with our products, please feel free to reach out. We are always happy to help!
