The Omnipure ELF-5M-KDF-P is an Extra-Large Format commercial-grade filter combining 5-micron carbon block filtration with KDF-55 and phosphate scale inhibition for demanding food service applications. Its bayonet-style replaceable body and permanent head design streamline maintenance in high-volume environments where chlorine, heavy metals, and scale formation are persistent concerns.

INSTALLATION & USE
Installing the ELF-Series Filter
- Shut off water supply and relieve system pressure before removing the old filter cartridge.
- Align the bayonet-style filter body with the permanent head and twist clockwise until it locks securely into place.
- Turn water supply back on and check all connections for leaks, then flush the system for 3-5 minutes to remove carbon fines.
- Monitor filter performance and replace every 10,000 gallons or annually, whichever comes first.
COMPATIBILITY
Application Fit
The Omnipure ELF-5M-KDF-P is designed for commercial food service installations requiring high flow rates and robust scale inhibition. The 4-inch diameter Extra-Large Format fits Omnipure ELF-Series housings with bayonet-style mounting systems. The combination of carbon block, KDF-55, and phosphate makes it well-suited for ice machines, beverage equipment, and commercial espresso systems where both water quality and equipment protection are priorities.
🔧 The phosphate component works best when water temperature stays below 90°F—installing this filter on cold water lines only will extend both its scale-inhibiting performance and the overall service life of downstream equipment.
