Omnipure (CK5720) 14"x2.5" Cuno SQC CS-572 Compatible 1 Micron Carbon Block Filter
Omnipure CK5720 14"x2.5" Cuno SQC Compatible Filter
Cost-effective replacement for Cuno 3M CS-572 bayonet-style systems. NSF-approved 1 micron carbon block in a durable injection-molded body that fits your existing head without the premium price.
Engineered for bayonet systems without the OEM markup
Direct CS-572 Replacement
Designed specifically to fit Cuno 3M SQC bayonet heads. The CK5720 drops into place of the CS-572 without adapters or modifications to your existing system.
1 Micron Carbon Block
Compressed carbon block provides dual-action filtration. Removes chlorine taste and odor while the 1 micron rating captures sediment, cysts, and particulate down to microscopic levels.
NSF-Approved Materials
Constructed entirely from NSF-certified injection-molded polypropylene. Every component meets National Sanitation Foundation standards for potable water contact.
Value Alternative
Omnipure CK-Series filters deliver OEM-equivalent performance at a fraction of the cost. Same bayonet fitment, same filtration capacity, better price per gallon filtered.
Fits Cuno 3M SQC bayonet-style systems
The Omnipure CK5720 is engineered as a direct replacement for Cuno 3M CS-572 filter cartridges. Compatible with any water filtration system using the Cuno SQC (Sanitary Quick Change) bayonet mounting head. Dimensions are 14 inches length by 2.5 inches diameter. Verify your existing head accepts bayonet-style cartridges before ordering.
Replacement schedule for the CK5720
Standard Residential
Replace every six months for typical household use with municipal water. Carbon block capacity degrades with chlorine exposure and particulate loading over time.
High-Volume or Poor Source Water
Reduce replacement interval if you notice flow rate decline, taste changes, or if your water has high sediment or chlorine levels. Commercial applications may require more frequent changes.
Flow-Based Replacement
If your system has a pressure gauge, replace the CK5720 when you see a 10-15 PSI drop from baseline. This indicates the carbon block is loaded and filtration efficiency is compromised.
Tool-Free Changes
Bayonet mount twists on and off by hand. No wrenches, no hassle, no water spills during cartridge replacement.
Made by Omnipure
Omnipure has manufactured water filtration cartridges for over 40 years. The CK-Series represents decades of carbon block engineering.
Stock Up and Save
CK5720 filters have a long shelf life when kept sealed. Buy multiple cartridges to lock in pricing and ensure you have replacements on hand.
