About This
- Protect Your Family and Household Appliance from Chlorine and More: Say goodbye to smelly, bad tasting water!

- Individually wrapped, standard sized 10” x 2.5”, high capacity activated carbon block (CTO, Chlorine, Taste, and Odor) replacement filter cartridge for iSpring water systems and most industry standard 10” reverse osmosis RO and under sink systems
- 5 micron coconut shell carbon and compact fabrication tech to achieve 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
- 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!
