Nu-Calgon 4339-10 Claris Small Replacement Water Filter Cartridge

The Nu-Calgon 4339-10 Claris Small Cartridge (also known as Everpure EV4339-10) is a commercial-grade replacement water filter cartridge engineered for hot beverage, espresso, coffee, steam, and iced tea brewing equipment. It combines advanced filtration and water softening in a single, compact cartridge, eliminating the need for separate treatment systems.

At the heart of this cartridge is DUOBLEND™ bypass technology, which allows precise, adjustable control of carbonate hardness levels to match the specific water recipe required by your equipment or preferred brewing profile. The adjustable, ion-selective filter lets technicians dial in the ideal mineral balance for optimal beverage flavor and equipment longevity.

5-Stage Filtration Process:

• Stage 1 – Prefiltration: Removes coarse particles and sediment before they enter the system
• Stage 2 – Carbonate Hardness Adjustment: Ion exchange process reduces scale-causing minerals to protect equipment
• Stage 3 – Fine Filtration: Captures smaller particulates for cleaner water output
• Stage 4 – Carbon Block: Highly efficient activated carbon removes chlorine, harmful contaminants, and unpleasant tastes and odors
• Stage 5 – Solid Membrane Filter: Removes particles down to 5 microns for the highest level of equipment protection

Key Specifications:

• Micron Rating: 5 µm
• Maximum Flow Rate: 0.5 GPM
• Maximum Pressure: 116 PSI
• Capacity: Approximately 396–450 gallons of coffee/hot beverage
• Can be installed in vertical or horizontal position

Filtration Features:

• Chlorine reduction
• Ion exchange (water softening/conditioning)
• Particulate reduction
• Scale control
• Taste and odor improvement

The Claris Small Cartridge is an ideal solution for lower-volume commercial coffee brewers, espresso machines, boilerless steam ovens, and iced tea equipment. Its compact size, tool-free cartridge replacement design, and flexible installation orientation make it a practical choice for space-constrained installations. Cross-reference: Everpure EV4339-10.
