Upgrade Your Water Quality: Pentair CTO-20 Replacement Cartridge for Cleaner, Better-Tasting Beverages
Introducing the Pentair CTO-20 Replacement Cartridge, a revolutionary 20-inch drop-in cartridge designed to elevate your beverage quality by significantly reducing sediment to 0.5-microns and diminishing chlorine, taste, and odor. This high-volume filter cartridge offers an impressive flow rate of 3.0 gallons per minute (gpm) and is capable of treating up to 30,000 gallons of water, ensuring your beverages are consistently pure and delicious.
System Advantages: Elevating Beverage Quality and Reducing Operational Costs
- Enhanced Beverage Quality: The Pentair CTO-20 cartridge guarantees that both cold and hot beverages taste better and are of consistent quality by improving water clarity and purity.

- State-of-the-art Filtration Technology: Featuring gradient-density depth filtration, it effectively removes dirt, rust, and debris as small as 0.5-microns, while activated carbon filtration eliminates chlorine taste and odor, protecting equipment from corrosion and wear.
- Cost-Effective: The high volume of the Pentair CTO-20 cartridge reduces the need for frequent replacements, making it a more economical choice over proprietary quick-change filters. Additionally, it generates less waste, as only the cartridge needs replacing.
