Omnipure (CK5620-P) 12"x2.5" Cuno CS-511,CS-531 Compatible 1 Micron Carbon Block & Phosphate Filter
Omnipure CK5620-P Carbon Block & Phosphate Filter
Direct replacement for Cuno CS-511 and CS-531 systems. 1 micron carbon block with integrated phosphate scale inhibitor in a cost-effective bayonet-compatible body.
Carbon block filtration plus phosphate conditioning in one cartridge
1 Micron Carbon Block
Compressed carbon structure removes chlorine taste and odor while filtering sediment, particulates, and chemical contaminants down to 1 micron.
Phosphate Scale Control
Integrated phosphate media inhibits scale formation and corrosion in plumbing and equipment, extending system life and maintaining flow rates.
Bayonet Body Design
The CK-Series replaces expensive OEM cartridges with a durable polypropylene body that fits existing Cuno permanent bayonet heads without modification.
NSF Approved Materials
Constructed entirely from NSF-certified materials for safe contact with drinking water. Injection-molded construction ensures consistent quality and reliable sealing.
Direct replacement for Cuno Water Factory systems
The Omnipure CK5620-P is designed as a compatible alternative to Cuno 3M CS-511 and CS-531 filters. Fits 12-inch bayonet-style permanent heads with 2.5-inch diameter housings. This filter is part of the Omnipure CK-Series line (catalog number 2708), engineered specifically to work with SQC (Sanitary Quick Change) systems that use twist-and-lock bayonet mounting.
Replacement schedule by application
Commercial/High Use
Beverage equipment, coffee machines, ice makers, and high-traffic applications
Residential/Standard Use
Under-sink drinking water systems, refrigerator connections, light commercial use
Performance-Based
Replace when flow rate drops significantly, taste changes, or scale buildup returns
Lower Cost Alternative
Omnipure CK-Series filters deliver OEM performance at a fraction of the price of original Cuno replacement cartridges
Drop-In Replacement
No tools, no modifications. Twist out the old cartridge and twist in the CK5620-P using the existing bayonet head
Dual-Action Filtration
Carbon block handles chlorine and contaminants while phosphate media prevents scale formation and metal corrosion downstream
Standard Dimensions
12 inches by 2.5 inches, the industry standard size for bayonet-style quick-change systems
