Hydronix - CB - 20" x 2.5" Coconut Carbon Block Filter
20" x 2.5" Coconut Carbon Block Filter
High-purity coconut shell carbon block engineered for superior chlorine reduction and whole-house or point-of-use applications
The Hydronix CB Series carbon block delivers exceptional chlorine reduction and filtration performance at a price point that makes sense for both residential and commercial installations. Available in 1, 5, and 10 micron ratings, this 20" x 2.5" cartridge fits standard whole-house and point-of-use housings. Manufactured from high-purity coconut shell activated carbon with minimal fines release, it outperforms traditional GAC and PAC filters in applications where consistent chlorine removal matters.
Why the Hydronix CB Series Stands Out
Coconut Shell Carbon
High-purity coconut shell activated carbon provides superior adsorption properties and longer service life compared to coal-based alternatives
Exceptional Chlorine Reduction
Engineered for aggressive chlorine removal in municipal water applications, protecting downstream equipment and improving taste
Multiple Micron Ratings
Choose from 1, 5, or 10 micron ratings to balance flow rate and sediment filtration for your specific application needs
Reduced Carbon Fines
Advanced manufacturing process minimizes carbon dust and fines, eliminating black water during startup and filter changes
High Dirt-Holding Capacity
Dense carbon block structure captures sediment while maintaining flow, extending filter life in challenging water conditions
Cost-to-Performance Value
Premium filtration performance at a competitive price point makes the CB Series ideal for high-volume replacement applications
Where the Hydronix CB Carbon Block Fits
The Hydronix CB Series 20" x 2.5" carbon block is designed for standard whole-house filter housings, point-of-use systems, reverse osmosis pre-filtration stages, and commercial filtration equipment. Compatible with any system accepting 20-inch by 2.5-inch cartridges. Ideal for well water treatment, municipal water improvement, food service applications, beverage equipment protection, and industrial process water. This cartridge replaces traditional GAC and PAC filters in applications requiring consistent chlorine reduction and sediment filtration. Use in residential whole-house systems, under-sink filters, RO systems, coffee and ice machine pre-filters, and commercial water treatment installations.
Hydronix carbon blocks are manufactured to strict quality standards and trusted by water treatment professionals across residential, commercial, and industrial applications.
