Hoshizaki 4HC-H Replacement Water Filter Cartridge — 21,000 gal, 2 GPM

Boost ice quality and equipment efficiency with the Hoshizaki 4HC-H replacement filter

The Hoshizaki 4HC-H replacement water filter cartridge is designed for single-configuration filtration systems and helps keep ice makers operating at full capacity by reducing scale and contaminants that can hinder performance. Crisp, clear ice can be a hallmark of consistent beverages and satisfied guests, and cleaner water supports that experience.

Key filtration benefits

• Reduces up to 99.99% of disinfectant chlorine from incoming water, helping to cut tastes and odors in ice.
• Filters dirt, rust particles, and other particulates as small as 1/2 micron, supporting clearer ice.
• Sub-micron filtration helps remove cysts and delivers crisper, fresher tasting ice.
• Includes H-GUARD Plus Antimicrobial Agent to provide ongoing protection in the filter medium.

Performance and compatibility

• Max flow rate: 2 GPM; working pressure: 10–125 psi; temperature: 35–100°F.
• Capacity: up to 21,000 gallons; inlet head: 3/8 inch; dimensions: 6" W x 10" D x 21" H.
• NSF/ANSI STD 42 Class 1 for particulates, taste/odor, chlorine, and a bacteriostatic effect; suitable for Hoshizaki icemakers.
• Designed for single configuration water filter systems; compatible with single, double, and triple filtration setups.

Usage notes and maintenance

To maintain performance, replace the cartridge roughly every 21,000 gallons or 6–12 months, depending on usage and water quality. Note that the 4HC-H is not recommended for flakers and is shorter than some earlier models.

Why choose the 4HC-H

• Delivers consistent ice quality by reducing lime scale and mineral buildup.
• Potentially lower maintenance needs due to cleaner water and smoother operation.
• NSF-certified filtration attributes support confidence in filtration performance.
