iSpring FC25B High Capacity 20” x 4.5” Water Filter Replacement Cartridge - Carbon Block - Fits Standard 20” x 4.5” Whole House Water Filter Systems
About this item
- Protect Your Family and Household Appliance from Chlorine and More: Say goodbye to smelly, bad tasting water! The FC25B carbon block filter is specially designed to remove up to 99% of chlorine from water as well as taste and odor compounds.
- Standard Size: Our filter set fits standard 20” x 4.5” housings, including brand name models.
- Our FC25B CTO Carbon Block filters are made of coconut shell activated carbon to increase filtration efficiency and extend filter life. Activated carbon is an effective adsorbent because it is a porous material and provides a large surface area to which contaminants may adsorb. They are tested by an independent third-party to meet NSF/ANSI standards. Water flow: up to 15 GPM.
- Peace of Mind Customer Service: Register online to activate your manufacturer warranty and life-time free tech support from U.S. local support team. We stand behind our products and if you encounter any problems with any of our products please reach out to us immediately. We are happy to help!
- Please Note: The 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). If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

Great price. Water tastes great. These are huge and should last a long time before needing replacement.

I highly recommend this filter. Works great for water with heavy chlorine smell/taste.

I have to admit that we are spoiled by this whole house water filter. Have been drinking lots of water ever since. While on vacation recently, my wife tasted some arrowhead and thought it was gross tasting by comparison.
